Chronicle III: January to March 2016

I’m sorry there was no blog last weekend. Frustratingly, the thing I spent that time on now isn’t going to work out, so I’m determined to make sure there is a post this weekend, and the post that is due is the next round-up of my academic life, which has now reached 2016. It has been five months since I posted the last of these three-month slices, and the only real consolation there is that it took me less time to get through those three months of blog content than it did the previous one, but we will hopefully still see further gains made as marking ebbs and the summer shapes up. Can but hope, eh? But meanwhile, here’s how it looked at the beginning of 2016 for your humble blogger.

Teaching

It’s not just tradition but also a reflection of the real state of life that the first item on the bill is always teaching. Actually, in the first half of 2016 I had a lower teaching load than I have had since or likely ever will at Leeds, given what they need me to cover; I was running one module, albeit a big one, and contributing bits to a couple of others. That said, the beginning of the semester was still a fairly steep learning curve, as the module I was running was an inherited first-year course called Empire and Aftermath: The Mediterranean World from the Second to the Eighth Centuries, and even my undergraduate study experience only previously went back to AD 284; I’d never done the second or third centuries before in any context, let alone one where I needed to show expertise. Thankfully I had the help of two postgraduates who’d taught the module before and that made everything easier, although I did also have to second-mark and observe those postgraduates so they were not solely a labour relief. It was all a fair bit of work, and it coincided with the early part of the excellent but intensive Palaeography: Reading Medieval Manuscripts that we put our MA students through, which has continuous assessment. Furthermore, Leeds has examinations on the first semester’s modules as soon as the students get back in January, so I was reading up for the new stuff and choosing manuscript images for palæography at the same time as marking these exam scripts, and by the time I was done with those the first palæography assignments were in, and they were only just back to the students by the time the first-years’ formative essays came in, alongside the second palæography assignments… and in general it seemed a long time before the marking stopped.

Wolfenbüttel MS Codex Guelfybertiani 13, fo. 6v

One that was set; can you read this? Come to Leeds and we’ll teach you! But if you want to know more independently, it is Wolfenbüttel MS Codex Guelfybertiani 13, folio 6 verso, and you can find out more via the link through the image

In between these I fitted a couple of workshops for an Institute for Medieval Studies module, Medieval Narratives on the Modern World, on European national origin myths and on the so-called Reconquista, but those were fun and much less work. And there were also personal tutorials to be fitted in, to which only half the students turn up but of course you must book the time anyway, and feedback meetings, and also joint care of a visiting Chinese Ph. D. student. I felt fairly busy. Still, looking back, I was not carrying very much and the next year would have been much harder if I hadn’t had this run-up.

Extra Labours

That must also be how I had time for the other things I was doing. In particular, having found out that there was this coin collection in the bottom of the Library, I had resolved to make it part of my teaching, and so one of the few changes I did make to Empire and Aftermath was to turn one of the seminars into a coin-handling session to try and get people excited about the reality of the period in their hands. I’m not sure how well that worked, though commendably both my postgrad assistants leapt at the chance to be able to say they’d taught with coins and did some crash-course Roman numismatics with me, which made me feel useful. More prosaically, in the state of the collection there wasn’t really a way to find out what there was to teach with except to inventory it, so I put aside my Friday afternoons for most of this period to inventory the medieval, Byzantine and late Roman coins and got through a fair few. Some day soon I will get round to sorting out the photographs I took of the cool ones…

Copper-alloy 40-nummi of Emperor Constans II overstruck at Constantinople in 641-642 on a coin of Emperor Heraclius, DOC II Constans II 59c, Leeds, Brotherton Library, uncatalogued

Here is one that perhaps only I could think is cool, a horribly-made copper-alloy 40-nummi of Emperor Constans II overstruck at Constantinople in 641-642 on a coin of Emperor Heraclius, DOC II Constans II 59c, Leeds, Brotherton Library, uncatalogued

There was also other stuff involving coins. Back at the Barber Institute the process of replacing me had unfortunately crossed with their normal exhibition schedule, so my humble effort, Inheriting Rome, was extended for a few months to give the new curator a chance. I got to see my thus-prolonged exhibition again because there were still two more sessions of the now-legendary All That Glitters project to do, about which I will tell you shortly, and of course back at Leeds this was also the time in which I started the wheels turning on the project that would become Unlocking the Winchester Cabinet. My head of department was actually concerned that I was going to spend all my time doing late antique numismatics and not the research on whose basis I’d been hired, which I didn’t see as a serious worry because, at this point, there was still time and I used it on stuff that was interesting and useful for others as well as for me.

Other people’s work

I was also at this point still managing to travel for seminars a bit, and I have a lot of notes from this period that I’m not really going to say much more about. The itinerary looked like this, though:

  • Katherine Cross, Dominic Dalglish and Robert Bracey, “Images, Relics and Altars: comparing material religion on the first millennium”, Earlier Middle Ages Seminar, Institute of Historical Research, University of London, 20th January 2016, to which I went mainly because Robert is an All That Glitters collaborator, but at this stage he was also busy with a project called Empires of Faith, which was doing the kind of cross-cultural comparison implied by their title here, with Katy Cross bringing early English Christian monuments like the Gosforth Cross to the table, Dominic Dalglish coming from the ancient Mediterranean world and Robert from Kushan India, but here talking as much about what made for valid comparison in this set-up as the actual objects. This was interesting but the results of the project can now be investigated on the web, so I’ll leave this one aside and move on to…
  • Hugh Kennedy, “ISIS and the Early Caliphate”, Centre for the Study of the Middle Ages Annual Public Lecture, University of Birmingham, 27th January 2016, to which I travelled down and which I thoroughly enjoyed, but which needs treatment together with…
  • Julia McClure, “A New Politics of the Middle Ages: a global Middle Ages for a global modernity”, Medieval History Seminar, University of Leeds, 3rd February 2016, also substantially about the way people were reading the Middle Ages into the situation in the Middle East at that time, but approaching it from a very different direction. So I’ll do a post about those two together.
  • I also made it down to London for Alex Rodríguez Suárez, “The Komnenian Emperors: a Latinophone dynasty”, Earlier Middle Ages Seminar, Institute of Historical Research, University of London, 11th February 2016, about the extent of the changes brought about in Byzantine court ceremonial under, especially, Manuel I Komnenos that would be attributed to Latin influence, which Dr Rodríguez wanted, I think rightly, to read as appropriation of ways to assert dominance over the new Latin lords in the Middle East, not an aping of their flashy chivalric habits as they have often carelessly been read. That seemed convincing to me but I don’t have much more to say about it, so on to a clutch of things back at Leeds, as follows:
  • Pat Cullum, “‘Looking the Part’: presentation and representation of clerical masculinity in late medieval England”, Medieval History Seminar, University of Leeds, 24th February 2016;
  • Esther Eidinow, “Seeing into the Future? Oracles and the Ancient Greeks”, Classics Seminar, University of Leeds, 25th February 2016, about ancient Greek stories in which oracles were tested before being consulted for real, pushing at the edges of our categories of rational and irrational, interesting and my first step in a plan to make friends with my counterparts in Classics and Ancient History;
  • Natalie Anderson, “Tournament Trappings: Textiles and Armour Working Together in the Late Medieval Joust”, Medieval Group Seminar, University of Leeds, 7th March 2016, the culminating presentation by one of our Ph.D. students then about to finish and very much a mature piece of work about the ways in which combatants in late medieval tournaments displayed and distinguished themselves, which was as much or more a matter of fabric as the armour that more often now remains to us.
  • Then, back to London again to see a big name, Philippe Buc, “Eschatology, War and Peace: of Christ’s Armies, Antichrist and the End of Times between ca. 1095 and ca. 1170″, Earlier Middle Ages Seminar, Institute of Historical Research, University of London, 10th March 2016, arguing for a change in the way that medieval people thought about the oncoming end of the world that occurred with Crusading, in which it becoming OK to kill for God was itself a sign of the end times, but one that could last for quite a long while, setting up the fight that would now go on until everyone was Christian and the End finally came. I remember this being fun and extremely erudite, but looking back over my notes I’m not sure what I have to add to that summary, so it’s back to Leeds for two more to close the season, the relevant items being:
  • Travelling the World: from Apuleius to the Icelandic Sagas, from the picaresque novel to travel literature, a more substantial seminar in Classics whose separate components were:
    • Regine May, “Travelling to the Land of Witches: Apuleius’s Golden Ass“, about Thessaly’s Classical reputation as a hotbed of magic and sorcery and how travel might thus lead you out of the known world in several dimensions, and
    • Ros Brown-Grant, “Encounters between the East and West in Fifteenth-Century Manuscript Cultures”, on pictures of Westerners meeting Easterners either in West of East as imagined by Western manuscript artists, usually for tales of betrayal where Greeks were concerned or conversion where Muslims were, sort of inevitably.
  • and finally, Ross Balzaretti, “Early Medieval Charters as Evidence for Land Management Practices”, Medieval History Seminar, University of Leeds, 16th March 2016, to which I would have gone even had it been further afield since Ross has been a supporter of mine for a long time and I am very interested in his work, but precisely because it’s quite similar to my own, I’m not going to do a detailed write-up here because it would look a lot like, “Ross’s charters say things like mine do!” It was good, but you can already read the same sort of thing here.

My Own Research?

So that brings us to the end of the timespan, and I have only promised three extra posts out of it this time, though actually there are also one news and two tourism posts that should also be fitted in there. But what is as ever missing is my own research. What was I working on in this period, looking back? Well, for one thing I was finishing revisions on the conference paper that nearly wasn’t, “A Problem of Concavity”; the final version of that was fired off into what became a suspicious silence in the middle of February 2016. After that I seem to have turned to the reading to support the revision of my venerable paper on early medieval crop yields, of which I’d done the bulk while still at Birmingham, and I had a new draft of that done in March, although, it would seem, not one I thought submissible; that was still a way off, and I now don’t recall why. But beyond that it’s hard to see what I was doing, and the conclusion has to be, I think, that despite the apparently light load I was struggling. I would build up academic muscle from here, and reluctantly trim back a lot of the activity above to make other things possible, but at this stage I was still enjoying being an established academic as I’d imagined it and seen it done by others, as well as reading a lot for teaching, and perhaps not getting that balance entirely right, in retrospect. I think, also, I still hadn’t actually worked out how to schedule research in a job that finally actually included that as a duty, but had structured time only for other activities. Actually accepting that it was a legitimate use of my employers’ time to read a book, after years governed by the next deadline, was still proving weirdly hard for me… Of course, I still was governed by the next deadline, functionally, but I was only letting others set them, wherein a mistake with future complications. Anyway, this story will be continued! But for now there’s enough queued up to write about, and this has already been a long post, so I’ll wrap it here and thank you for reading.

All That Glitters, Experiment 5

Fittingly in some ways, given the distressing news of the last post, this post takes me back to Birmingham (which continues to happen, with a trip there on Wednesday coming that I will delight in telling you about before long if all goes to plan…). In fact, this is the last of the posts promised in my second Chronicle round-up, which means that we are now progressed in the story of my academic life to December 2015… It doesn’t look a lot like blogging progress, but let’s ignore that and instead tell the next part of the story of my project to zap Byzantine gold coins with X-rays, All That Glitters.

Bruker S8 TIGER XRF analyser open for business

The maw of the S8 TIGER XRF analysis machine in the Department of Chemistry, University of Birmingham, already much featured in these posts

It’s getting a little silly now to re-summarise the project every time I do one of these posts, however far apart they may be, so I’ll invite you to look here for the premise and just say where, by December 2015, the project had got up to. In brief, we had started from a belief that we might be able to find out about sources of metal for the Byzantine coinage and how those changed and maybe why by analysing them using a technique known as X-Ray Fluorescence (XRF). We got money to investigate this possibility in April 2015, and either before that or thereafter moved through the following developmental steps:

  1. finding out that the lightweight, energy-dispersive kit that we had hoped to use just wasn’t going to get the information we needed;
  2. finding out that the big, stationary, wavelength-dispersive kit we had to use instead (by kind courtesy of the Department of Chemistry, University of Birmingham) would get us the best results only on its longest cycle, cutting the number of things we could test in the time we could pay for down considerably;
  3. finding out that the results we were getting apparently included quite a lot of invisible surface deposits that seemed most likely to be leftover soil;
  4. discovering that, against all expectations, cleaning the coins in acetone actually made this problem worse, if anything;
  5. deciding, along the way, that we could not, as we had hoped, test different areas of coins for comparison of homogeneity either, because the results were just too darn variable to interpret;
  6. establishing that despite all these limitations, we could still distinguish between mint practices sometimes, but that only in the most difficult of cases was this telling us anything a competent numismatist couldn’t have seen by thmselves;
  7. and, although this was my colleague Dr Rebecca Darley, not myself, presenting these initial findings at the International Numismatic Congress in Taormina and at the Joint British Museum/Institute of Archaeology Seminar at University College London.1
  8. At the former of these presentations we got some pushback from the numismatists whose work we were implicitly questioning, which was understandable, but in the latter we got lots of pushback from one or two archaeometallurgists who felt that we were not people properly trained to do such work and that in fact it was pointless, which I saw as one of those ivory-tower problems; people are out there doing such work badly anyway, so would you rather just let them publish it and be accepted or shall we aim to do at least a bit better?2 Admittedly, we were having trouble doing much better, but that was what we now set about solving…

On 17th December 2015, therefore, three of us brought our test set of coins back to the Department of Chemistry, but this time with a difference. We’d already tried cleaning the coins in acetone, as said, so we had decided that we needed to try harder. But how hard should you try to clean a relatively soft precious-metal object of considerable value? Thankfully, this was a question that the team working on the Staffordshire Hoard had already faced, and since I’d been able to talk with one of them earlier in the year, we had a kind of answer, which was, berberis (or barberry) thorns: tough enough to shift surface dirt, soft enough not to scratch the metal!3 So before the test, Maria Vrij, by now in post succeeding me as Interim Curator of Coins at the Barber following my move to Leeds, had taken the coins and more acetone down to the Barber’s most suitable room for the purpose and, with the windows wide open, had laboriously worked over their surfaces with thorns under a magnifying glass.4 I can only say that this made me very glad to have moved jobs before this could have become my task, and I remain very grateful to Maria for doing it, but of course the real question was, what difference did it make? And the answer was, sadly, ‘a bit’: the levels of presumably-surface material that shouldn’t really be in the coins (calcium, silicon, potassium, aluminium) dropped, but were not gone.

This was, in many ways, not the answer we wanted, as with so many of the findings thus far. We would much rather not have had to use the big, fixed machine to which the coins had to be brought, rather than one of the portable ones we could have taken to other collections; we would rather have been able to use a shorter test cycle and thus test more things in the time we had; we’d rather not have had to clean the coins at all; but if we had to clean the coins, we’d rather it had been possible just with a wash and a rub in acetone, not with hours of picking at them with thorns with your face close over a bath of solvent. If we had (and by we, I really mean Maria, sorry Maria), to do all that, however, we’d at least have liked it to produce good results. What it actually produced, however, was only measurably less bad results, which was not the exciting scientific conclusion for which we might have hoped. But it might be a bit more like actual science, and sadly, it’s a lot more like real life; messy, never quite sorted out, but still interesting…


1. The former of these papers is now published, in fact, as Rebecca Darley, “All that glitters…: the Byzantine gold solidus, c. 300-1092″, in Maria Caccamo Caltabiano (ed.), XV Internationa Numismatic Congress, Taormina 2015: Proceedings (Rome 2017), II, pp. 982-985. A cite for the latter would be Rebecca Darley, “What does the science mean? Interpreting metallurgic analysis of Byzantine gold coinage”, unpublished paper presented at the British Museum/Institute of Archaeology Joint Seminar, University College London, 15th December 2015.

2. It seems mean to point fingers, but once it’s being cited it is probably fair game and, on the basis of our experiments, I might raise questions about Rasiel Suarez, “A Metals Analysis of Silver Roman Imperial Coins using X-Ray Fluorescence Spectroscopy”, online here, whose precision just seems impossible with the equipment he used despite his checks (which were not carried out against a standard), and one would like at least to be able to ask more questions about the methods and reproducibility of the tests in Monica Baldassarri, Gildo de Holanda Cavalcanti, Marco Ferretti, Astrik Gorghinian, Emanuela Grifoni, Stefano Legnaioli, Giulia Lorenzetti, Stefano Pagnotta, Luciano Marras, Eleonora Violano, Marco Lezzerini and Vincenzo Palleschi, “X-Ray Fluorescence Analysis of XII–XIV Century Italian Gold Coins” in Journal of Archaeology (2014), pp. 1–6, online here. Note that we are not the only researchers wondering about things like this, by now: see also V. Orfanou and Th. Rehren, “A (not so) dangerous method: pXRF vs. EPMA-WDS analyses of copper-based artefacts” in Archaeological and Anthropological Sciences Vol. 7 (Basel 2015), pp. 387–397, DOI: 10.1007/s12520-014-0198-z, and E. S. Blakelock, “Never Judge A Gold Object by its Surface Analysis: A Study of Surface Phenomena in a Selection of Gold Objects from the Staffordshire Hoard” in Archaeometry Vol. 58 (Chichester 2016), pp. 912–929, DOI: 10.1111/arcm.12209.

4. Of course, she is no longer Interim, but now actually properly Curator of Coins, and much better at it than ever I was, despite the acetone fumes!

Name in Print XVIII

The chronology of the content in these posts is a struggle for me to follow, so I dread to think what it’s like for you, dear reader, but despite that, having now shown you more photos of medieval places from late 2015, I now want to bring you forward to April 2017, when somewhat to my surprise, a new publication of mine I’d more or less entirely forgotten about suddenly turned up in my pigeonhole at work.

You see, in the final frantic days at the Barber Institute of Fine Arts, in which I had been counting all the coins, trying to ensure that my two dissertation pupils had what they were due from me and that the office would be usable by my successor, as well as maintaining a cheerful and helpful demeanour in the face of unexpected requests from members of the actual museum-going public, I also got asked to make some contributions to an update of the Barber’s introductory guide to its collections. These are mainly what you’d call ‘fine art’, but the old one had had coins in and it was thought best that these be updated in the light of what we now knew about the collection as a result of my tenure there. I did that quite quickly, though of course professionally, signed it all off in the last month I was there and forgot about it, and then 20 months later there it was in a pigeonhole in Leeds with me listed as one of the co-authors.1

Title page, including my own name

It is perhaps a sign of the way that the world of museums works that of the five named authors, only two still worked at the Barber by the time it came out—we’d noticed the same churn in the All That Glitters project, where all the remaining participants were in different jobs by the time we finished—but I felt especially flattered by my name appearing there, because my entire contribution to this book on which I am named is three of the six coin entries, probably a total of about 500 words. (The others, like a lot of the text, remain from the previous edition.) So this is a very generous, and probably undeserved, co-authorship, but I was of course inordinately pleased by it anyway. And as ever with museums versus academia, more people will probably read those entries than any of my actual academic work!

Gold ducat of Grand Master Pierre d’Aubusson struck at Rhodes 1476-1500, Barber Institute of Fine Arts CR0037

The actual coins that got the benefit of my attention were these, a denarius of the Roman Emperor Claudius showing Nemesis (because we had to replace the previous Roman coin entry), a drachm of Shahanshah Shapur II (because the Barber has a really good collection of Sasanian coins that wasn’t even mentioned before and I insisted), and a ducat of the Knights of the Hospital of St John struck at Rhodes, because it’s unexpectedly flashy, one of those dissertation students had helped me identify it not long before, and because I was determined to get some of our medieval in there as well.2 (The other coins in the catalogue are a tetradrachm of Lysimachus I, a solidus of Emperor Leo VI and a sovereign of Mary Tudor.) So I did those things (including getting the coins online, where they are), and they can thus be seen! And now you know.

Statistics, as long as we’re counting: obviously, this work was never presented, and it went through only one draft, as I’ve described. What that also means, of course, is that it ran a pretty standard year and eight months from first submission to print, stretching that average out just that bit further, but in a volume with this many moving parts that is perhaps not too surprising, and I’m completely happy with how it came out, which is maybe more surprising by now!

An awful lot of numismatists in Sicily, I

The progress of this blog continues surreal. I returned from India yesterday, and am nearly three years overdue in writing the next post, about going to Sicily. Nothing loath, here goes, in an attempt to write maybe my shortest ever conference review about one of the largest conferences I ever went to, the Fifteenth International Numismatic Congress, which was held in Taormina, already mentioned, from the 21st to the 25th September 2015. It is too large for one post, in fact, and there is a very obvious break-point in the middle, so this will be part I of II.

Logo of the XVth INC

I travelled to the INC in a sort of party of people one way or another connected to the Barber Institute of Fine Arts and its coin collection, which I’d still been in charge of when I signed up. We arrived the night before, I think, bussed in from Taormina’s delightfully, er, unreformed airport, past those Byzantine graves already mentioned, and stayed in a tiny but charming hostel room for the duration. The papers were split across four different venues in the town, all splendid and close by each other; it was easier and quicker getting between sessions here than at Kalamazoo, for example, than whose campus the whole town might even be smaller, but one had to resist buying tat (or just coffee) between each one in a very definite way. Proceedings began the next morning with a series of welcoming addresses, but I’ve no memory of those and no notes on them, and one was by someone I know, so I think that for one reason or another I didn’t get going until later. The best way to record what I did go to seems to be to list the papers for each day, then make remarks, but that still winds up fairly long. So I shall put it behind a cut, but encourage you to look even if only for the pictures, which are not what you’d expect from the average academic conference. Continue reading

Chronicle I: July, August and September 2015

I’m back in the UK, and even if you’re not, you may have gathered that quite a proportion of this country’s academics are currently on strike about proposed cuts to our pensions. In theory, therefore, I can do nothing like work today, but for various reasons I think blog can be allowed; after all, given that the main reason I haven’t been blogging regularly of late is my job, it seems all sorts of perverse if when the job halts I still can’t blog. So, without further ado, I’m going to test out the new format with a short account of the three months of my academic life following the last backlogged event I covered, a conference in Lincoln which you can go and read about if you so desire.

The Barber Institute of Fine Arts, University of Birmingham

We begin here… The Barber Institute of Fine Arts, University of Birmingham

Now, I say my academic life but it’s even more difficult to separate that from the rest than usual for this particular patch of my existence, as in this time I was transferring that existence from Birmingham to Leeds. The two themes of my life in this period were therefore movement between cities, and counting coins. The latter was because one of the things the Barber Institute had hired me to do when I started there was an actual audit of the coin collection, whose records from the previous few years were sadly not all they should have been. In the event, it was only once I knew I was leaving that I really got started on that, becuase immediate priorities were all more, well, immediate. But now it had to be done, so I was spending most of any given working day in the coin room comparing trays to spreadsheets, and occasionally finding where someone had evidently dropped such a tray at some point then put things back in the wrong places. There were only a few of those but they really slowed things down… But it did, finally, happen and I wrote a big report which not only confirmed that the Barber was then in possession of 15,905 coins, 35 tokens, 22 medals, 165 seals, 42 weights and 10 other objects of paranumismatica, as well as collections not formally part of its holdings like the so-called ‘Heathrow Hoard’, but gave them something much more like a firm footing for future development of the collection. At the same time I was also setting up a lecture series for my exhibition, which I was now going to miss, processing uploads which you already heard about, and zapping coins with X-rays on occasion. It wasn’t a bad job, really. Oh yes, and I was also supervising two MA dissertations, one of which was on the Heathrow Hoard, indeed, so there was some teaching even though it was outside term.

So all that was busy enough, but in August my old diaries and e-mails betray a slow shift: correspondence about workshops I would be doing in Leeds, moving company quotes, a farewell party at the Barber (bless them) and eventually the actual close of play. Somewhere in there, of course, was also happening the slow packing-up of stuff and eventually it all going into a Pickfords lorry, in coordination with my partner’s stuff coming up from London to be so shipped as well, and finally our actual installation into what we then thought would be our new home for the foreseeable future. I also did a medievalist tour of Dudley with a couple of friends, and I will post about that separately, with photographs, because there is actually medieval stuff to photograph there. But it’s September where the itinerary just gets crazy: from Leeds to Birmingham on the 8th, crashing for one last night in my now-empty previous home to hand over white goods and keys the next day, and then back to Leeds; to London and then Harpenden, of all places, at the weekend for a gig, then back to London and back to Leeds; and back down to Birmingham again on the 15th, for reasons I’ll say more about in a moment, and back up to Leeds again on the 16th; and then on the 20th I flew to Sicily, where I was for the following 6 days for reasons I’ll likewise mention below. And the day after I got back, we had to start having our house hot-water system replaced and I started teaching in my new job, opening up my career there with a lecture on Charlemagne and the Carolingians, all fairly fitting I think. Up to that point I’d been on campus quite a lot anyway, for induction and training, and also organising next year’s frontiers sessions for the International Medieval Congress, but now it had really started.

Can it be that we have got so far through this post without an actual coin? Here’s a good big ugly one to make up for that, a copper-alloy follis of Emperor Justinian I struck at Cyzicus in 543&ndash544, Barber Institute of Fine Arts B0692

I’m still quite smug about the second Birmingham trip, just because it involved seeing an opportunity coming from a long way off at a time when I was otherwise completely lost in the weeds of the job. As I mentioned, there were a set of lectures intended to support my exhibition at the Barber. For various reasons they took a long time to organise, and I was having trouble finding suitable guest speakers. But as the date slipped back and the new job became clear, I suddenly realised: by the time they happened, I could myself be a guest speaker, because I would no longer work there! So that’s what I did, giving my successor in the post the job of introducing me for a lecture I’d set up. Perhaps it shouldn’t seem like a triumph, but it did. After all, if you want something done, do it yourself… The lecture was called “Small Change and Big Changes: minting and money after the Fall of Rome”, and it basically went through the changes that the imperial coinage system underwent as large parts of the Roman Empire fell into the control of non-Roman rulers, using Barber coins as illustrations throughout; the background idea was that of the exhibition, that we are still the heirs to Rome’s monetary and iconographic vocabulary of power, but the foreground was much more me working out ideas that I intended to take into the classroom; the lecture title is, after all, suspiciously similar to that of one of my current modules

So, what haven’t we covered? Well, one thing that this new post format means sacrificing is the old write-up of trips, papers and conferences. I should still mention what they were, however, I think, so this is the list such as it was:

  • 3rd August: the medievalist outing to Dudley and Claverley, of which there will be separate photo posts;
  • 12th August: Eleanor Blakelock, “Secrets of the Anglo-Saxon Goldsmiths: underlying truth of the Staffordshire Hoard”, a seminar in the Department of Physics at the University of Birmingham whose details have now gone from the web, but a very useful contact with someone who genuinely knows about metallic analysis of early medieval gold, which resulted in an exchange of references as well as some useful knowledge about how Anglo-Saxon goldsmiths seem to have made their work look shinier;
  • 23rd August: an actual visit to the then-new display of the Staffordshire Hoard in Birmingham Museum and Art Gallery, which was good but probably isn’t worth recording separately for you all at this long remove given how much coverage the Hoard has already had here;
  • 21st–25th September: the XVth International Numismatic Congress in Taormina, Sicily. This needs a post of its own, and I’m not quite sure how I’ll keep it to one, but I am determined; it was a good but intense experience and I’m still trying to find out if my paper at it will be published. As you might imagine, I also managed to fit in some medievalist tourism here and there will be photos of that too.
  • 29th September: David Hinton, “Personal Possessions in Medieval England: archaeology and written evidence”, Institute for Medieval Studies Public Lecture, University of Leeds: my first academic event at my new job put one of the great figures of Anglo-Saxon archaeology before me and he was, of course, interesting; he emphasised the great spread of standards of living and wealth that Anglo-Saxon and medieval English material culture covered, from subsistence farming with almost nothing incidental owned (or at least lost) up to hoards of treasure such as have already been mentioned. Nonetheless, probably more people than that implies had precious items, however paltry; these were kept for lifetimes, which can make dating them from context difficult to do, but were also often metal and therefore recyclable, so the evidence all needs careful interpretation. Of course it does! But here was someone very used to doing that who made it sound manageable.

So, firstly that sort of summarises two and a half of the busiest months of my life until last year, but secondly I seem already to have promised five more posts of various kinds, mainly photos. I’d better therefore leave this one here and thus properly establish the new state of the blog! More will follow! After all, we haven’t got our pensions back as yet…

All That Glitters, Experiment 3

A problem with finally picking up this blog a bit is that some of the old stories in it have been sitting idle for really quite some time. Does anyone remember, for example, that while I was working at the Barber Institute we got a small amount of money to zap gold coins with x-rays? If you do, you may remember that I’d already reported on the first two experiments we did in that project when everything here ground to a halt in 2016. Well, now I resume, with a brief account of the third experiment we did, and before long who knows, we may be through the rest!

A brief recap may be in order first of all, though. The very short version of the project’s purpose was: we had all seen an increasing amount of work using X-ray fluorescence spectrometry to analyse the fineness of precious-metal coins and sometimes even assign origins to its metal based on the trace elements therein. We had our doubts about this, but the manufacturers of some of the best machinery involved wanted to quell our doubts about this and offered us quite a lot of help with it, so we came up with a plan and, somewhat to our surprise, got both permission from the Henry Barber Trust to muck around with their coins and funding from the Royal Numismatic Society to do it, and so set about it. We began this in December 2014, with two experiments. The first was designed to test the viability of hand-held, portable, energy-dispersive machinery that could be brought to the coins; the second did comparator analyses using a fixed-location wavelength-dispersive spectrometer to which we had to bring the coins. This showed us that to detect anything at all of trace elements we would need the big machine, but also that it was picking up a whole load of stuff that seemed very likely to be extraneous material on the surface of the coins, probably from the soil in which they had long ago been found, rather than the stuff of which they were actually made. And that is about where we come in!

The coin whose results (and details) are given in the first table below, set up for the test in which it did so

So, the third experiment was very simple. Using the same set of coins as we had previously run, I got hold of some conservation-quality acetone and a toothbrush, took them and the coins down to a workroom in the depths of the Barber and gave them all a careful but thorough scrubbing and let them dry, all except one that we left uncleaned as a check. Then I packed them up again and we bore them off to the Department of Chemistry on 22nd July 2015. There we ran them again, on the shorter of the big machine’s two cycles, and this gave us some results both before and after cleaning.

Unfortunately, if anything, the post-cleaning results showed more extraneous grot. That ‘if anything’ will tell you, though, that consistency was hard to observe. The variation wasn’t vast amounts, you understand, between half and one-and-a-half per cent, but cumulatively certainly enough to push our figures for the actual gold content up or down by two or three per cent, which would for some people be enough on which to found a theory about debasement… Here are the top ten elemental results from just one side of one coin by way of example:

Coin 170 (obverse)1 Percentage observed first time Percentage observed second time
Gold 86.51% 84.49%
Silicon 3.44% 4.63%
Silver 1.61% 1.43%
Aluminium 1.27% 1.19%
Potassium 0.80% 0.63%
Sodium 0.74%
Copper 0.44% 0.34%
Calcium 0.32% 1.96%
Sulphur 0.28% 0.48%
Iron 0.27% 0.50%
Total percentage of coin observed 96.38% 96.70%

Down by two per cent gold, and that mostly gone to silicon and calcium, even though some other small elements had dropped in the readings as well. Also, what this arrangement doesn’t show, the second time small but possible readings showed up for chlorine, magnesium and, way down the scale, platinum, all absent the first time through. Surely cleaning with acetone couldn’t have added calcium to the coin? But each coin we ran had its own little tale of additional mess to tell, even (and this should have told us something) the uncleaned check. Here are its top-ten figures for the obverse:

Coin 21 (obverse)2 Percentage observed first time Percentage observed second time
Gold 82.57% 87.43%
Silicon 1.82% 1.61%
Aluminium 1.01% 0.81%
Silver 0.74% 1.10%
Sodium 0.65%
Potassium 0.47%
Chlorine 0.45%
Calcium 0.44% 1.78%
Iron 0.31% 0.31%
Copper 0.24% 0.26%
Total percentage of coin observed 89.12% 93.80%

Some things are beguilingly similar, yes—iron and copper levels stay about the same—but others are not. The first test picked up sodium, potassium and chlorine but none of those turned up second time even though we’d actually got better readings with more of the sample observed (possibly because we gave it a flatter bit to look at). Were we just looking at a different bit? If so, that bit apparently had less silicon in it, but a whole whack more calcium in it. What can you do with these sorts of data?

The uncleaned check likewise set up for the results above, though I have to say it’s not like it looks dirty

So this was somewhat daunting, especially as we had four solid days of testing booked in for the following week and now somewhat less certainty that it would produce anything. At the time, my best guess was that the acetone had removed only handling patina, thus exposing the actual surface of the coin and everything that had adhered to or reacted into it while it was in the ground. Actually, looking back, I think we were already seeing here the conclusion that the final experiment would necessarily lead us to. But that would be getting ahead of the story, and even though this story is so very far behind, I have hopes of telling it as I wanted to anyway. So, till next post but, er, two, if I have my plans right (and no-one else dies—did you see Mark E. Smith has left us for the bar of the great and final WMC since the last post?), I shall leave the question hanging…


1. We used randomly-allocated running numbers throughout these experiments, so that we couldn’t try and guess what the results should be according to where the coins fitted in Byzantine history (or the previous curves laid down by work like Cécile Morrisson, Jean-Nöel Barrandon and Jean Poirier, “La monnaie d’or byzantine à Constantinople : purification et modes d’altérations (491-1354)” in Morrisson, Claude Brenot, Barrandon, Poirier and Robert Halleux (edd.), L’or monnayé I : purification et altérations de Rome à Byzance, Cahiers Ernest Babelon 2 (Paris: C. N. R. S. 1985), pp. 113–187. This one was actually Birmingham, Barber Institute of Fine Arts B4599, a solidus of Emperor Constantine VI and Empress Eirini struck at Constantinople between 785 and 797, online here. I’m actually almost loath to identify the coins here, though, lest it be thought I’m actually publishing figures for their metal content. As is probably clear, though, that’s something I’m sure we weren’t reliably getting.

2. And this one was Barber Institute of Fine Arts B0006, a solidus of Emperor Anastasius I struck at Constantinople between 491 and 518, online here, with the same reservations as in the previous note.

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

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.
