When is a hoard not a hoard?

In the Barber Institute of Fine Arts in the University of Birmingham there is a black box, about as big as the ones A4 printer paper come in, which contains 275 coins. Almost all of them are copper-alloy of some description and they are collectively known as either the Balkans Hoard or the Heathrow Hoard. I was faced with this even before I began work there as Interim Curator of Coins, because they used it as an interview test, and they will never know how I only had the faintest idea what any of it was because of frantic reading of Philip Grierson the week before.1 (Never.) One of my assigned responsibilities while in that job was to produce a report on this box, which I duly did in February 2016, by which stage I also had a master’s student working on it for her dissertation and plans actually to publish it with her. Somehow, by the end of my tenure in post those plans had not much advanced, and so in October 2015 as I gathered my various responsibilities up in the new job I decided that this project was still among them, and stubbed this post to tell you about it. As it happens, a few days ago I signed off the first part of the project, a skeleton formal catalogue, and so it’s all very timely how these things (slowly) come around.

A copper-alloy follis of Emperor Anastasius I, struck at Antioch in 498-518, Barber Institute of Fine Arts B0151. This isn’t one of the coins in the box; I don’t seem to have a picture of any of the folles therein, but it’s not unlike them except by being from Antioch; there’re only a couple of Antioch coins in there, and they’re both of Justinian I.

I noticed even at the interview that this supposed hoard was not one, at least as the word is usually understood. The most obviously identifiable components were big early folles of Emperors Anastasius I (491-518), Justin I (518-527), Justinian I (527-565) and Justin II (565-574), but on the other hand a goodly part of what was in the box was concave billon, and so late-eleventh-century or later. The implied 500-year span pretty much precludes this being a single assemblage; while certainly folles circulated for a very long time, it’s not half a millennium by anyone’s reckoning and the concave coins and the old flat ones probably couldn’t have been part of the same system. (Probably. Assuming there was actually a system. Anyway…)

Billon aspron trachy of Emperor John III Ducas, otherwise known as John Vatatzes, struck at Thessalonica in 1249-1254, Barber Institute of Fine Arts BH0173

This is a lot more like what the state of the ‘hoard’ is generally like, and is, we think, a billon aspron trachy of Emperor John III Ducas, otherwise known as John Vatatzes, struck at Thessalonica in 1249-1254. You can imagine how much fun the identification was… The Barber has not formally accessioned the ‘hoard’, but this coin’s provisional access number is Barber Institute of Fine Arts BH0173. Not to scale with previous coin.

Further investigation only deepened this paradox. Firstly this was because we were able to identify more of the components. The later end included not just this twelfth-century concave stuff, mainly of Manuel I Komnenos (1143-1180) but some later still, but bits and pieces of the Latin Empire of Constantinople and its Thessalonican rival and really quite a lot of medieval Bulgarian material, most of all of Tsar Ivan Alexander (1331-1371) though again, a bit later. The absolute outlier was a grano of the Holy Roman Emperor Charles V (1519-1558)! Meanwhile, we had checked into the provenance, because the ‘hoard’ had originally come to us from the British Museum, and we had only received the Byzantine portion. It turned out that what they had kept was another 400-odd coins, mostly from the period of the Roman Empire but going back as far as Alexander the Great (336 BC-323 BC). So that date range was now up to nearly 1900 years and the issues of some very different states. It’s not a hoard!

Except, it kind of is. A hoard is by definition an assemblage of valuable items (whether personally or monetarily valuable) deposited with the intent of recovery, right?2 Well, the other documentation we got from the British Museum clarified a lot of things. This particular assemblage was deposited in a set of carrier bags, behind a loose panel in a bathroom on board an aeroplane staging through London Heathrow airport on its way between Sofia and Washington DC. If that’s a ritual deposit, I’m pretty sure it’s only because shipping stuff out of Bulgaria to sell on the US market has now become almost a regular practice.3 Someone was meant to pick this up. As it happened instead, it was discovered by a cleaner and taken over by Her Majesty’s Customs and Excise, who decided in due course that there was no prospect of returning it to its owner and that therefore it fell under a legal doctrine called ‘last resort’, which meant that rather than lose it to world heritage by dumping it on the open market it could be deposited with a UK museum. So the British Museum got it and gave some of it to the Barber. (This was in 2004; I believe the law about this changed in 2008.) It’s a fascinating group, has some actual numismatic novelties in it we think, and the combination of what’s in there allows one to make some educated guesses about where it was coming from (which my student bravely did, on the back of considerable research4), but it’s most fascinating as a collection, I think, because of the story by which it has become a hoard. It’s one of the things I’m working on, anyway, and, while it is temporarily out of my court, you can expect some day to hear more about it here.

1. Reading, of course, P. Grierson, Byzantine Coins (London 1982) which, if it doesn’t have all the answers, at least has most of the questions and some good guesses with illustrations to help. If you ever have to gen up on Byzantine coinage in a week, I recommend it!

2. For example, P. Grierson, Numismatics (Oxford 1975), p. 125: “A hoard is by definition a group of coins or other valuables which was concealed as a unit….”

3. This is the bit that needs the most substantiation, really, isn’t it? But you could start with Tihomir Bezlov & Emil Tzenkov, Organized Crime in Bulgaria: markets and trends (Sofia 2007), pp. 177-198, or Nathan T. Elkins, “A Survey of the Material and Intellectual Consequences of Trading in Undocumented Ancient Coins: A Case Study on the North American Trade” in Frankfurter elektronische Rundschau zur Altertumskunde Vol. 7 (2008), pp. 1–13, online at http://s145739614.online.de/fera/ausgabe7/Elkins.pdf, last modified October 2, 2008, as of October 12, 2009. I found these cites while researching what became Jonathan Jarrett, Reinhold Hüber-Mork, Sebastian Zambanini & Achille Felicetti, “Coinage, Digitization and the World-Wide Web: Numismatics and the COINS Project” in Brent H. Nelson & Melissa Terras (edd.), Digitizing Medieval and Early Modern Material Culture, New Technologies in Medieval and Renaissance Studies 3 (Tempe: University of Arizona Press 2012), pp. 459-489, but look, they have become useful again because the problem did not end with what these people knew about…

4. I can’t replicate her bibliography here, not least as I don’t have a copy, but the place to start for the Anglophone is D. Michael Metcalf, Coinage in South-Eastern Europe 820-1396, Royal Numismatic Society Special Publication 11 (London 1979), even now.

Another Gathering of Byzantinists in Birmingham

My reporting backlog now reaches 30th May 2015, which was a very full day in Birmingham occasioned by the 16th Annual Postgraduate Symposium of the Centre of Byzantine, Ottoman and Modern Greek Studies, with the title Fragmentation: the Eastern Mediterranean in Conflict and Cohesion. I have dithered before about whether I report on what is essentially a postgraduate event, but it’s a postgraduate event with a keynote by an established scholar and people come to it from all over the world, so it’s really as high-level as such things get and the people participating in it are all working at their highest level. So, I shall blog it, but as the backlog is so long and time is so short I shall try to be brief and hope it still does the participants due credit. I should stress, though, that looking through my notes for this, the number of times I have said to myself, “Oh! I met so-and-so then?” or even, “Oh? I ran that? I have no memory of this at all” has been much higher than it really should be for anyone of even my advanced age. I was clearly just getting by at this point in my life on not enough sleep, and while things have come back to me as I write this, we are basically reliant on my notes for what I’m reporting, which may be wrong or inadequate. So if you were there, I invite corrections!

The caravanserai of Kesik Köprü

The caravanserai of Kesik Köprü, in the erstwhile Seljuk Sultanate of Konya

We began with the keynote address, which was by Professor Scott Redford and entitled “84 Mongols Walk into a Caravanserai…”. This promising start was occasioned by a document, signed indeed by eighty-four Mongols, mostly local officials of various grades, at the caravanserai of Yüksekligi, to witness the act of one Nur ad-Din ibn Tayā as he established a church. The document is dated to the Year of the Monkey and has a gloss in Mongol. With this example of how cultures were mixing in the thirteenth century in what is now Western Turkey, Professor Redford then picked out a number of other ways in which we can, if we choose, find links between Greek, Turkish and yes, even Mongol cultures of patronage and power in this area. For example, Nur ad-Din had also built a caravanserai at Kesik Köprü, which is still up as you can see above, on the route between Constantinople and the local Sultanate of Konya, and stands near a bridge which went up at about the same time and only fell down in 1990, but contained an inscription set up by the Sultan of Konya when he was actually in rebellion against his masters in Baghdad, and so closer to the Greeks than the Turks in some ways.

I was personally less convinced by some of the art-historical links which Professor Redford drew, but the widespread use of a symbol called the ‘elibelinde’, seen below, in Constantinople (and indeed more once it became Istanbul), various locations in the Seljuk sultanates and indeed yet another local caravanserai, did speak loudly of a cultural identity that crossed and blurred political boundaries that were in any case more fluid below the top, state, level than we sometimes remember when doing history in outline. So this was good, and full of much better illustrations than I have been able to use here.

After this we were down into the postgraduate sessions. I had volunteered to chair one of these, so my choice about what to go to was made for me, but in fact this put me into my first ever contact with two future colleagues so unbeknownst to me it worked well. Also, the papers were interesting. They were these:

  • James Hill, “Missing the Opportune Moment: John V Palaiologos and the spectre of union”
  • Nafsika Vassilopolou, “Royal Marriages of the Palaeologi (1258-1453): appraising a political practice”
  • Maroula Perisanidi, “Should We Abstain? Marital Equality in Byzantine Canon Law”
  • All these papers were about one or other sort of union, really. James was looking at the agreement of Emperor John V to re-reunify the Eastern and Western Christian churches, an agreement that in the end collapsed not just because of its deep unpopularity in the eastern Empire (where it doesn’t even seem to have been made public as a plan) but also and perhaps mainly because the popes simply couldn’t deliver the troops that were John’s asking price, despite their best diplomatic efforts with Genoa and Venice. Ms Vassilopolou’s paper made it seem odder that the eastern emperors had such trouble enjoining union of the Churches on their people, because when it came to marrying off princesses there was pretty much no theological objection which they could not overrule: consanguinity, juvenility, differing religions or sects of Christianity… What is less clear is what most of the eighty-eight political marriages the Palaeologan emperors arranged actually got them: alliance, sometimes, especially with the Mongols who seem to have received the most consistently high-status brides, territory sometimes, but it usually cost a lot in terms of land, money and human capital as well, and Ms Vassilopolou thought that the main motivation was to remain on the international stage as a player, not an extra, which as we know in the UK is a strategy that can make you do some very stupid things. Lastly Maroula went looking for gender equality in Byzantine canon law, hoping to find it at the most fundamental point: who got to choose when to abstain from sex? The trouble here is that most of the law deals with churchmen, who by reason of needing to perform holy office weekly and being supposed to abstain before and after were much more often confronted by this question, so that kind of comes pre-gendered. It was quite surprising to me how much thought the Byzantine canonists had put into this question, but I suppose it did keep coming up (if you’ll forgive the phrase). The paper is now out in print, anyway, so you can read it yourself if you like!1

That took us to lunch, and then after that, the programme tells me, I was dashing back to the Barber Institute to give a coin handling session, “Coins of Byzantium and its Neighbours in the Barber Institute of Fine Arts”. I have literally no memory of this, although I remember correspondence about it, but it’s in the programme and I have a handout from it in my notes, so I guess it happened! I was apparently basically showcasing the Byzantine collection, from beginning to end, or at least, as close to the end as I thought we could get, a solidus of Constantine I to a half-stavraton of John VIII. (I later discovered two coins of Constantine XI in the collection which the Curator for whom I was standing in had acquired but never accessioned; they are there, if you want to see them.)

The route between the two took us via Justinian I’s reforms, Heraclius’s mighty beard, the strange mixture that is Arab-Byzantine money, Komnenian concavity and the various daughter coinages of Byzantium; I picked Trebizond, Venice and Hisn Kayfa, all of which tells you that I was finally beginning to get my head round what this collection had to offer and what, had circumstances been otherwise, I might have done with it. But with the alternative path laid out before me already, it was still really nice to be able to show off some of its shiny and curious components. Then, it was back up the road to where the papers were.

  • Yannis Stamos, “Kazantzakis’s Representations of the Greek Civil War: the divided vision of socio-political fragmentation”
  • Mike Saxby, “Arms in Exile: an analysis of military iconography on coins of the Byzantine successor states”
  • Carl Dixon, “From Armenia to Bulgaria? The Transmission of Heterodoxy in Peter of Sicily’s History of the Paulicians
  • The first of these was the only paper on the programme representing the Centre’s Modern Greek component, a study of two novels by the 1940s Cretan writer Niko Kazantzakis, Christ Recrucified and The Fratricides, arguing, I think, that Kazantzakis was trying to find an ethic that might heal his riven country in the form of a grass-roots socialism well infused with Christian charity, a community religious mutual help ethic; the paper overran and had to be cut short, so what the conclusion was to have been I have no idea. Mike, who was one of the vital sources of institutional memory when I took over at the Barber, went into the messy period after 1204 when Byzantine rulers-in-exile set up in Nicæa, Thessaloniki and Epiros, all of whom struck coin which generally diversified from the fairly standardised Constantinopolitan money of the previous period. Mike noted that although all tried out images of armed rulers and saints to different degrees, Thessaloniki had Saint Demetrius with a sword on more than half of its coin types, which as he said could be down to the six-hundred-year tradition there of the saint as the city’s military protector but could also just be down to the fact that Thessaloniki was most exposed to war, mostly with the Bulgarians who also by now claimed Saint Demetrius as a protecting saint. Several kinds of politics vie for expression in the coins, therefore. Lastly Mr Dixon took us into the history of a disputed text about the dualist Byzantine heretics known as Paulicians.2 The History in question purports to be from the 870s and to be a warning to the Byzantine administration that the group plans to mount a mission to convert, or subvert, the Bulgarians, but this cannot easily be; the situation it foresees had in part come about by the eleventh century, but the themes of the early tenth century, when the movement seems newly to have been observed, place it in Armenia, and it was only moved to the Balkans by Emperor John I in the late 970s. The text is thus very hard to date, and while Mr Dixon didn’t want to rule out that it was just a forgery given how little knowledge it seems to have about the settlement at Tephrike where it is set, he certainly felt that any evidence that it existed and was being used in the early tenth century, as has tended to be assumed from the text’s own claims, needed reexamination. Discussion suggested a few ways this might be done, but none of them were easy, so it’s quite the mission Mr Dixon had ahead of him.

Then tea and then back into the sessions for the last round of papers, which took me back to the early Middle Ages where, really, my interests are.

  • Anna Kelley, “Rethinking Cotton Use and Cultivation in Late Antique Egypt”
  • Catherine Keane, “More than a Church: the archaeology of the economic reality of Christian structures in the late antique Mediterranean”
  • Maria Vrij, “The Anomaly’s Anomaly: the curious case of gold coin production at Syracuse under Justinian II”
  • Anna laid out for us a peculiar picture of cotton use and cultivation before the seventh century, in which it was far from unknown but for most people hard to get, and found only in certain areas; there was cotton growing on the Red Sea coast in the fourth century, for example, and in the Western Desert over the Nile, but not at points between. The current suggestion of a source seems to be Nubia but even there it’s hard to show cotton being grown for export, rather than just for local use. There’s a network here yet to be pieced together, which is roughly where Anna’s research comes in of course! Ms Keane was at a similarly early stage, and her basic question was about the relocation of economic production in Northern Africa, of oil, wine and so on, out of Roman rural industrialised complexes into cities and then, increasingly, localising out to the then-fairly-new churches. The focus of production seems therefore to be following the focus of public space, which is something that, like cotton, looks like there is more to be found out. although Ms Keane’s paper was full of citations indicating that the process has started.3 Lastly, Maria, my right hand at the Barber at this point and now my replacement there, was asking why, when Emperor Justinian II famously (to readers here at least) put a portrait of Christ on his gold coinage, the mint at Syracuse didn’t follow suit. Syracuse was rarely exactly on the Constantinopolitan model when it came to minting but this seems sufficiently outright a refusal of imperial authority as to need explanation, which might be offered in terms of a Western resistance to images of the divine, and one which was followed after Justinian’s death in all quarters, indeed. The discussion here circled somewhat around who this message might be for, the world of Islam or the coin-using public, and who they might be, all of which, sadly, the coins don’t really tell us.

The final part of the symposium was a closing address by Professor Redford, who somewhat unconventionally started by asking the organisers why they’d picked this theme. With that answered he pointed out gaps and strengths in the programme and its adherence to the theme but reassured everyone that the Centre of Byzantine, Ottoman and Modern Greek Studies was still showing a flag for the value of study clusters like it, and the day closed with pretty much everyone much satisfied by how things had gone.

Announcing Buried Treasures

I no longer work at the Barber Institute of Fine Arts, as keen readers will know, but you could be forgiven for making the mistake given that while I deal with the backlog about half the things on the front page of this here blog are posts about objects at the Barber and that until a few weeks ago they were displaying my work in the form of the exhibition Inheriting Rome, which for reasons I explained a while back has had the benefit of a considerably extended run while the new Interim Curator of Coins, Maria Vrij, got appointed and to work. This, however, she has now done and the results in the form of a new exhibition, Buried Treasures: Uncovering Hoards, is now open and I got to go to a private view.

I could, if so minded, at least claim an assist on this as, when it still seemed that I would be setting up the next exhibition after Inheriting Rome, I had the idea of displaying some of the hoards that reside in the Barber in their entirety, of which there are several, one of which I am even working towards publishing. They are all kind of bronze and damaged, however, and it remained an undeveloped idea. Maria, however, who has always known the Barber Collections far better than I got to, was also aware that lots of items in the collection had come from hoards, and that has proved the seed for a rather brilliant exhibition.

Introductory case, naming and placing the 1945 Carthage Hoard, the 1954 Tunis Hoard, the 1957 Syria Hoard, ‘Hoard A’ from Syria, the Messina Hoard, the Dorchester Hoard, the Appleford Hoard and the Mardin Hoard, parts of all of which are on display

Using the hoards and their discovery as a platform, Maria has been able to open up in accessible terms many of the questions that lie beneath the practice of burying coins, such as: why do people do it? Are the purposes always the same? (To which, this exhibition makes abundantly clear, the answer is ‘no’.) What sort of coins get buried when? Where do the coins come from? Why were they not recovered? And what can they tell us, about the history of the coinage or about the history of their times?

There are also more specific research outcomes on display here. Maria is of course one of the investigators on the project All That Glitters about which I have written here, and as a result one small part of one case uses our findings from that to talk about metal purity in the Byzantine gold coinage. If you want to know more about that, firstly rest assured that further posts will appear here as I slowly tackle the backlog, but more immediately, this coming Wednesday the 18th May there will be a lunchtime lecture at the Barber with the title, “The Marriage of History and Science: Testing the Purity of Byzantine Gold Coinage” and the speaker will be none other than myself! It’s not really my work I’ll be presenting so much as the group’s, set into a context in which the general public can understand it (or so I hope), but it should be fun, it is free and if you happen to be in Birmingham that lunchtime perhaps you’d like to come along?

I am, though, almost more pleased with this inset, in as much as without committing itself to any of my theories on the question, this is actually based on my research, which of course I talked out with Maria while I was actually working on it.1 I never thought of displaying the coins in a way that made their fabric this visible, however. As with so many elements of this exhibition, it is not unlike what we did in the coin gallery before (and the designers deserve a huge credit for making it recognisable as well as different) but it is probably better, managing to do more with less and make it more accessible. It runs until 26th February 2017, but go and see it soon! Then you can go again before it closes!

Learning from an ailing emperor

The last two posts have involved rather a lot of me getting things wrong in a more or less embarrassing fashion, including about stuff I’ve either taught or written about. Obviously the thing to do next is to start giving opinions about a text written in a language I don’t even read, right? In fact, that might even be safer since at least here I know roughly how much I don’t know… But I have been meaning to write about this since the run-up to the Leeds International Medieval Congress last year, and my current somewhat shaky form isn’t going to stop me. So I want to introduce you to the work known as De Administrando Imperio by Emperor Constantine VII (913-959).1

You see, last academic year I was under a certain amount of social pressure to identify as a Byzantinist, what with the second-best Byzantine coin collection in the world (so it has been claimed) in my charge. I was also trying to get people to participate in a grand effort of comparison of medieval frontiers, and needed to come up with something for a Leeds session on that subject. And so I thought that it would be potentially interesting to compare what my speciality medieval magnate, Count Borrell II of Barcelona (945-993), did with his frontiers to what a completely different but roughly contemporary polity, which given my immediate circumstances should most obviously be the Byzantine Empire, did with some of its. And having declared such an intent, the obvious next step was the De Administrando Imperio.

Now, there are lots of things about this text that struck me and I want to write about at least a couple, without anticipating the actual paper too much since I have every hope that a version of it will some day go into print.2 But to say anything useful about what the De Administrando says it seemed more and more to me that the first step was to understand what it is, which should be simple but isn’t. What it immediately appears to be is a manual of statecraft by a Byzantine Emperor, written for his son and future successor Romanus II (959-963). In fact, firstly not very much of it is explicitly about the administration of the Empire and secondly quite a lot of it is not by Constantine VII.3 I’ll try and explain…

In the first place one has to understand Constantine’s own life situation.4 He was son of the successful Emperor Leo VI the Wise (886-912) but was only two when Leo died, so although he succeeded he did so alongside his uncle Alexander (912-913), who kept his nephew mostly excluded from power during his short reign. Once Alexander was dead Constantine’s mother Zoe became leader of a regent council, but was for one reason or another unable to hold onto that status and the admiral of the fleet, Romanus Lecapenus, more or less took power in 919, marrying his daughter Helena to Constantine in that year and then assuming co-emperorship in 920.

Over Romanus I’s long and more or less successful reign (920-944) power was shuffled and reconfigured again and again, it seems, with his own sons Christopher, Stephen and Constantine becoming co-emperors alongside and indeed in front of Constantine VII, in terms of how they were presented in public display and on the coinage.5 Another of his sons, Theophylact, became Patriarch of Constantinople in 933, although far too young. Christopher, who seems to have been the intended heir, however died in 931, and after that Romanus seems to have accepted that his other sons would not be able to keep Constantine VII from power, and returned him to a more obvious rôle. Constantine was spared the bother of a contest, however, because in 944 Stephen and his imperial brother decided they’d waited long enough, kidnapped their father and deposed him and when they returned to Constantinople the people rose against them and demanded that Constantine VII take sole power. Usurper father and rebels sons all died as monks, although Stephen outlived both Constantine VII and Romanus II. It’s a messy story.

What it all means for us, however, is that until 944 Constantine VII had a lot of time on his hands, and he seems to have spent a lot of this buried in books and the archives of the imperial palace. By the time he came to the throne he had a better idea than most about what the empire had been and some strong ideas about what it should now be, based not least on a series of treatises he had written, of which the De Administrando was only one.6 But he proceeded by compilation, pulling in materials of all vintages, so that the empire he reconstructed, and in the case of his book on imperial ceremony even enacted, was an empire that had never quite been, not all at once.

This applies no less to the De Administrando, but this raises particular excitement for scholars of the areas that he covers. These are, more or less, the frontiers with non-Islamic powers: it starts with the Pechenegs and the various other peoples who can affect them, including Rus’, Bulgarians and Turks, then talks at length about the way the Rus’ get to Constantinople, briefly about how to constrain the the Khazars, then goes off for many chapters into a reprise of the early history of Islam, largely retold from the Chronographia of Theophanes, all of which seems to be leading up to the point at which the ‘Abbasids lost control of al-Andalus to the one Umayyad they’d failed to kill, ‘Abd al-Rahman I. But that, 756, is as far as that thread goes and then he moves onto recent diplomatic relations within Italy, a matter of much more current concern as Romanus was married to a daughter of King Hugh of Italy (924-947). After that he proceeds more or less geographically, giving a historical ethnography of the various Roman and Slavic peoples of the Balkans, moving into the Caucasus and then appending a series of anecdotes about treaties and the manning of the imperial fleet. He finishes with two legends from Cherson.

From this you can see that if there was really an overall plan for this work, it was not adhered to very well. This has been explained by suggesting that Constantine had actually already nearly finished a different, more ethnographical work hypothetically known as the De Nationibus, and then before the final edit recycled its material willy-nilly into his new project for his son.7 But lots of that material is not only not his, but not reconciled at all with the other components of the work, which has suggested to many people that what we are getting here is nothing less than palace archival material copied without alteration, and often (it can be argued from the language used) based on or even actually being reports by local officials or informants from the areas concerned. This opens up for scholars of the early Slavs or the Rus’ the irresistible possibility that Constantine has preserved for them the earliest written records from their chosen peoples of study, and so there is great resistance to any suggestion that this is in fact a compilation of Constantinopolitan pseudo-history, selected by Constantine to justify baseless claims to imperial suzerainty of areas he couldn’t actually affect.8

And yet it sometimes seems as if it must be, because Constantine turns up so strongly as an authorial voice, which was the the thing that I liked best about reading the text. He starts the first chapter with a clear agenda:

“Hear now, my son, those things of which I think you should not be ignorant, and be wise that you may attain to government. For I maintain that while learning is a good thing for all the rest as well, who are subjects, yet it is especially so for you, who are bound to take thought for the safety of all, and to steer and to guide the laden ship of the world… I conceive, then, that it is always greatly to the advantage of the emperor of the Romans to be minded to keep the peace with the nation of the Pechenegs and to conclude conventions and treaties of friendship with them and to send every year to them from our side a diplomatic agent with presents befitting and suitable to that nation, and to take from their side sureties, that is, hostages and a diplomatic agent, who shall be collected together under charge of the competent minister in this city protected of God, and shall enjoy all imperial benefits and gifts suitable for the emperor to bestow.”

And he goes on with what is essentially a catalogue of people whom the Pechenegs can be induced to attack instead of the empire or who as allies of the empire may make the Pechenegs think twice before leaving their homeland open to attack by setting out against the empire. But it’s not long before that takes him onto ambassadorial routes to these people and then, apparently, he remembers this excellent account he has of bringing boats down the Dniepr from Kiev, and we’re off.9

Although a lot of the material can thus be explained as things it is useful for an emperor to know, some of it seems to have a bigger purpose, of presenting imperial claims in areas that lay well beyond the empire’s current control. On the former side there’s the intricate account of the recent politics of the Caucasus, important because almost all the rival potentates there had appealed for imperial support at some point and might do so again, always opening up opportunities for imperial expansion by force majeure. On the latter there are the quite dubious and much-debated claims about imperial Christianisation of the Balkans, which can be made into currently-relevant political statements but are at the least very odd ways to do that.10 Both of these cases are going to get their own posts, so I’ll not say more just now; instead, I’ll just add that not only do some sections, especially that on the Islamic conquest of Spain, not obviously serve any agenda beyond antiquarianism, but some are much more obviously personal. The little section on the imperial fleet—not the navy proper but a squadron maintained to carry the emperor and his officials in suitable style—is perhaps the most touching of these, where Constantine describes some of the men he remembers commanding the imperial galleys:

“When Podaron became vice-admiral, the protospatharius Theophylact Bimblidis was appointed protospatharius of the basin, who was nephew of the protospatharius John, surnamed Thalasson, and he lasted for a few years of the first reign of Constantine the Porphyrogenitus, the Christ-loving sovereign. On his death, since Michael the elder aforesaid [in a part not quoted here] was grown very old indeed and had given many long years of service as steersman, he was honoured with the rank of protospatharius and was also appointed protospatharius of the basin. And when the emperor embarked on the galley in the basin and set out either upon a progress or somewhere else, that good old man, ever memorable for his seamanship, would take his stand amidships of the galley, inspiring and urging the oarsmen of the galley to pull and row more bravely and manfully, and at the same time instructing the steersmen of the day how to manage the rudders and steer the imperial vessel when the winds were blowing distemperately. Well, he died….”11

I like this bit not just for the sheer irrelevance of Constantine’s genealogical detail—Romanus could surely get no benefit from knowing whose nephew an official of forty years before was—but because despite the third-person narrative, it’s clearly Constantine’s own memory we’ve got here, and it tells us that somewhere within the forty-five-year-old emperor who had spent much of his life as a virtual prisoner, albeit in a huge palace, was still the boy who had got to ride around on that galley and watch the elder Michael boss the sailors around in grand style.

Some of Constantine’s memories are less generous, and in particular, and understandably, he has almost nothing good to say of Romanus I Lecapenus. His words vary from lengthy accounts of why Romanus’s policy had been misguided, especially in areas where Constantine was now doing better, to straightforward character assassination:

“The lord Romanus the Emperor was an idiot and an illiterate man, neither bred in the high imperial manner, nor following Roman custom from the beginning, nor of imperial or noble descent, and therefore the more rude and authoritarian in doing most things … for his beliefs were uncouth, obstinate, ignorant of what is good, and unwilling to adhere to what is right and proper.12

One could certainly argue that this had a political purpose, since two of Romanus’s sons were still alive and, indeed, one Patriarch of Constantinople at the time of writing and might still have been seen as threats, and it’s an odd thing so thoroughly to insult your son’s grandfather in a work you’re giving to that son. This is not the only place where Constantine seems to have thought this work might have a wider audience, but on the other hand the contents could have been considered sensitive and the repeated addresses to his son make a specific audience also seem to have been intended.13

One is left to wonder if Constantine really knew what he was doing with this work, or if it was even really finished; it seems not to have been edited, as said, its chapter headings don’t always match its contents and Constantine seems to refer here and there to things he’s failed to say in other sections.14 One explanation of the state of it might be that the single surviving manuscript, which was copied in the second half of the eleventh century, was made up from something that was still a working copy, with notes and materials laid in that were never supposed to be part of the final version. The scholarship is pretty clear that the text was finalised in 952, however, because that is a date actually given as current at one point in the text and was the year of Romanus II’s fourteenth birthday, when he might have been considered to have come of age, and the opening proem not only names the author, in the first person, and the recipient, but gives a summary of the contents that seems to match the order of what we have.15 In other words it looks as if this is something like what Constantine meant it to be, although if so one wonders if our copy was made from the final version, if Constantine had in fact read over that version or if he was really working at full power. Later sources suggest that Constantine drank too much wine, and there is something about the way this text proceeds that does remind me of one knowledgeable but ageing alcoholic I knew well in his declining years.16 But if the De Administrando is, in fact, just badly put together, what does that do to our attempts to divine its various deeper political and intellectual purposes? Maybe they have also to be assumed to be not very well put together. And can we trust such an author to have reported or copied his sources accurately? These are questions people probably don’t want to deal with, as they threaten to diminish how much we know, but what mainly strikes me all the same is how very human Constantine comes across in his attempt to compile his uniquely imperial wisdom.

3. Also, it’s not called the De Administrando Imperio, in as much as it’s in Greek and it doesn’t have a title in any of the manuscripts, but this is what its first editor called it in an era when it was still considered necessary to give Greek texts a title of reference in a ‘proper’ language…

5. On the coinage, which has probably been assigned too precise a chronology on the assumption that its iconography precisely reflects the shifting balance of power in the reign, see Philip Grierson, Byzantine Coins (London 1982), pp. 172-188. The finer chronology proposed by Franz Füeg, Corpus of the Nomismata from Anastasius II to John I in Constantinople, 713-976: structure of the issues, corpus of coin finds, contribution to the iconographic and monetary history (Lancaster PA 2007), goes well beyond the demonstrable. I’d give page references but, really, you could say that of the whole book. Even he, however, has to admit (at p. 39) that Constantine struck solidi with both sole and accompanied portraits at the same time, which if it could be done obviously undermines the whole chronology based on who’s on the coins. This really should have been obvious from the copper-alloy coinage already.

All That Glitters, Experiment 1

Almost the last academic thing I did last year before breaking for Christmas was the first two sessions of a project that is now nearly finished, All That Glitters, announced here so long ago. It was so long ago that it might be worth reintroducing. Basically, by great happenstance one of my predecessors in taking care of the coin collection at the Barber Institute had run into two people at a conference who were presenting about the ability of the X-ray fluorescence (XRF) equipment their company, Bruker Industries Ltd., produced to do metal analyses. That predecessor, Rebecca Darley, also knew Robert Bracey at the British Museum, who had done work with XRF on the coinage of the Kushan Empire, and now I was in charge of the Barber’s coins. None of us are archæometallurgists and our knowledge of archæology and numismatics didn’t necessarily combine with the metals analysis expertise upon which we could call so as to somehow make a composite archæometallurgist out of us all, but Robert could borrow the British Museum’s handheld XRF scanner, Bruker had a new machine they wanted to test against real problems, the Barber is on the same campus as several much larger and more expensive machines also supplied by Bruker some of whose host departments proved happy to let us use them and to tell us about them; a project seemed obviously to exist in potentio and our task was to work out how to make it tell us something useful.

Bruker Industries Tracer IV handheld XRF analysis system

I’m not sure if this is the exact machine we were using but its resemblance to a phaser seems impressively reminiscent

It’s too early to say whether we achieved that, pending actual publication of our results and conclusions which we are even now working on writing up, but right from the beginning it was clear to us that before we could have any historical conclusions we would have to have methodological ones. This is because there are so many potential problems with XRF analysis, problems which not all publications using it consider, and when they do, consider most often for silver alloys rather than the high-purity gold we would be testing, that the first priority had to be not to find things out, but rather to find out what we could find out.1 Accordingly, our pilot experiments were designed to evaluate the machinery more than the coinage, and we started on the 3rd December 2014 when Robert brought the British Museum’s handheld scanner up from the British Museum, along with its calibration standard, and Mike Dobby and Colin Slater from Bruker brought in their new M1ORA energy-dispersive scanner and we put some coins through their x-rays.

The first coin to go under, a gold solidus of Emperor Anastasius I struck at Constantinople (in the Eta officina) between 492 and 507, Barber Institute of Fine Arts B0005

We had chosen a test set of ten coins running from Anastasius I (491-518) to Constantine VI (785-797), with two coins for each ruler from the same mint and if possible, the same workshop of the mint (if that’s what officinae were), hoping that whatever results we might obtain would thus be internally secure against outlier coins from a bad day at the mint or similar.2 All of those got zapped on both sides with both handheld and the microwave-like M1ORA. Both of these use a spot beam, but with the M1ORA it’s possible to target it precisely, so we aimed for flat surfaces wherever possible.

The initial results of this made the handheld device look like much the poorer sibling, as its readings were extremely variable. Robert worked out, however, that this was related to how much of its expected sample it had been able to observe—this in turn probably down to surface relief but already we were into unknowns—and when the figures were all normalised to a notional 100% of sample they came out much more like what the M1ORA was seeing. The M1ORA was able to dump its readings straight into a laptop equipped with suitable software, and did this levelling-up in that software, so made things immediately clearer for us by automating that step, solely an issue of configuration but we still needed to be aware of it. I keep stressing variables and difficulties because I don’t want to imply that we were getting actual true results, but that said, once they were both talking to us in the same framework the message of the machines was pretty consistent: all these coins were being analysed as very high-purity gold, 97% or more, which is astonishingly high for any pre-modern metallurgy. However, other than silver and copper, which occurred in about the proportions one would expect (i. e. not very much and even less), the only other element that was consistently detectable was iron. That was in part a factor of what we had asked Mike and Colin to make the machinery look for but if you have to do that at all, there is obviously a restriction inherent in your question-setting…

So then for something rather different, a gold dinar of Sindh imitating a Persian dinar of Shah Shapur II (309-379), struck at an unknown mint and date, Barber Institute of Fine Arts S0073

The very high fineness was sort of what we might have expected, anyway, as it is roughly what earlier analyses of Byzantine gold coins by a number of methods have suggested.3 It still made me uncomfortable for its lack of variety, however, and so since we had run-time left in the day I started hauling other things out of the cabinets. These included two Persian gold dinars, of Shahs Shapur II (309-379) and Varhran IV (388-399), and the above piece which is pretending to be something like the former, as well as an Arab-Byzantine solidus from Carthage and some more Byzantine pieces. Mainly I just wanted to be sure that the machinery actually would report lower gold finenesses, and so it duly did, with the Persian pieces both lower (but not by the same amount) and the Sindh piece even less fine (which, to be honest, was already apparent in its colour, but that was why I’d chosen it). The Byzantine stuff, and the coins imitating that, remained high in the machinery’s estimation.

A gold solidus of the second reign of Emperor Justinian II, struck at Constantinople between 705 and 711, Barber Institute of Fine Arts B4464

Another part of the starting sample, a gold solidus of the second reign of Emperor Justinian II, struck at Constantinople between 705 and 711, Barber Institute of Fine Arts B4464

This bit was fairly unsystematic sampling, but it did give us some reason to believe that the machinery was observing something consistent with our expectations, and which therefore fitted into existing understandings of the early Byzantine gold coinage. That is circular, though, obviously! This and the likely effect on the readings of differences between the surface of the coins and their cores, because of both manufacturing factors and subsequent environmental exposure, meant that we weren’t willing (and still aren’t) to say that these figures are actually how fine those coins were. We also weren’t seeing a range of trace elements which we had expected on the basis of older work, and which might have suggested things about changes in metal supply and treatment that would potentially be historical evidence.4 So, while these machines might serve other people’s purposes, we ourselves were going to need some bigger kit. And that would be Experiment 2, about which I shall write in a couple of posts’ time. In the meantime, however, here is some shiny metallic blogging for the Christmas season and I wish you all a happy holiday!

1. Part of our problem was that so much of the literature about these problems was old enough to relate, potentially, only to a much more primitive incarnation of the technique. Nonetheless, Michael F. Hendy & J. A. Charles, “The Production Techniques, Silver Content and Circulation History of the Twelfth-Century Byzantine Silver Trachy” in Archaeometry Vol. 12 (Oxford 1970), pp. 13-21, William A. Oddy, “The Analysis of Gold Coins—A Comparison of Results Obtained by Non-Destructive Methods”, ibid. Vol. 14 (1972), pp. 109-117 and J. Tate, “Some Problems in Analysing Museum Material by Nondestructive Surface Sensitive Techniques” in Nuclear Instruments and Methods in Physics Research Part B Vol. 14 (Amsterdam 1986), pp. 20-23, all suggest that differences should be observable between surfaces and cores of coins and between methods that measure only the surface and those that measure total composition, and L. Beck, S. Bosonnet, S. Réveillon, D. Eliot & F. Pilon, “Silver surface enrichment of silver–copper alloys: a limitation for the analysis of ancient silver coins by surface techniques”, ibid. Part B Vol. 226 (2004), pp. 153-162, DOI: 10.1016/j.nimb.2004.06.044 and Vasiliki Kantarelou, Francisco José Ager, Despoina Eugenidou, Francisca Chaves, Alexandros Andreou, Elena Kontou, Niki Katsikosta, Miguel Angel Respaldiza, Patrizia Serafin, Dimosthenis Sokaras, Charalambos Zarkadas, Kyriaki Polikreti & Andreas Germanos Karydas, “X-ray Fluorescence analytical criteria to assess the fineness of ancient silver coins: application on Ptolemaic coinage” in Spectrochimica Acta Part B Vol. 66 (Amsterdam 2011), pp. 681-690, DOI: 10.1016/j.sab.2011.08.001, give some explanations of why that should be so. (I have to thank Dr Eleanor Blakelock for some of these and several other useful references.) All of these except Oddy and Tate were working with silver alloyed with base metal, however, and so another of the problems we have is in knowing how far the same applies to gold and if it does, whether if alloyed with base metals only or also with noble metals such as we expected to see. And the mess only gets worse from there…

Entrevista a mi en Català

The seminar reports are catching up but reports on my other activity seem still to be mired in busy busy November 2014. At the very end of that month, I had the unusual honour of being interviewed for a Catalan history news website, a sort of recognition I’m very flattered to receive although I wish I could have given them a better photograph. Should you be interested, it’s here:

I should probably post the English, shouldn’t I? But I am writing this on a train to Birmingham to x-ray more coins and time and wi-fi are both scant, so I’ll wait to see if anyone wants it. Meanwhile, speaking of Birmingham, even while posting was sparse here I was still cropping up in other places on the Internet, not least the blog of the Centre for the Study of the Middle Ages, as follows:

And then lastly, though I will write properly about All That Glitters soon I promise, even as Cross Country Trains carry me towards the next session, here is a snapshot about one of those we already did:

I have never been so twitterfied! Anyway, with that I must get back to what I am doing now, but here at least is some record of what I have been doing that you didn’t have before!
