Framing the Late Antique and Early Medieval Economy, including X-rays

Since 2014 or 2015 there has been a large project running at Princeton University in the USA called Framing the Late Antique and Early Medieval Economy (acronymised to FLAME, rather than the more accurate but less sexy FLAEME). Its aim has been to put the study of the late antique and early medieval economy onto a firmer quantitative footing than has ever before been possible, by reasoning that coinage is the best proxy evidence for it and assembling an absolutely massive database of coin types and finds from all available data, published and where possible unpublished, in order that really large-scale conclusions can be drawn from it. In this respect, the project is either a rival of or a complement to Chris Wickham’s huge book Framing the Early Middle Ages, whose title of course the project is riffing off and which argued that ceramics were the best proxy evidence, though he does observe that it would be fantastic to do a parallel project with coinage.1 Well, this is that project, and it has reached substantial proportions; checking in on their website today tells me that they have 233,816 coins in the database from 2,806 finds, and I think that more are still being added.

Now, wherever a database is made questions arise about methodology, because data generated by actual live humans living their real lives tends not to fit analytical categories perfectly. When I first heard of this project, one of the concerns the people I discussed it with was that, by uncritically dumping every publication they could find into a database unchecked—because how could they possibly check them all, given available time and the difficulty of identifying and recruiting suitable expertise for some of the weird bits?—the project would just multiply errors of attribution and interpretation by completely unknowable amounts, leading to the kind of bad numismatic maths we have decried on this blog before now and doubtless will again. This turned out to be something they were thinking about at Princeton, but nonetheless, the temptation to make a snazzy visual can still outweigh such cautions: the animation above is based on several questionable assumptions, most of all steady output at the mints concerned throughout the possible period of issue of each coinage, averaged down to a yearly output. In short, you’re probably seeing most dots on that map for much longer than they would have been there, and of course a massive number of mints doesn’t mean a massive output of coinage; the Merovingian Franks ran 80+ mints at once at times, and for much of imperial history the Romans only struck at Rome, but it’s no difficulty guessing who was making more coin… But the video does at least illustrate where minting was happening and roughly when and shows what could be done with such data by people who know what they’re doing. And FLAME is or was full of people who do know what they’re doing, so there’s hope.

Now, that is roughly where things stood with my thinking when, in late 2015, while I was winding up my post at the Barber Institute, FLAME got in touch with me to announce that they were having their first project conference in April 2016 and asking if I would like to talk there about the All that Glitters project. I did, I admit, wonder why they had asked me rather than any of the people on our team who actually work on the late antique or early medieval economy; maybe the Barber job looked like seniority to them, in which case it’s ironic that by the time I went I no longer had it. But go I did, and this is my very very late report on the conference.

I had never been to Princeton before, and found it a surreal experience. Everyone was extremely nice, but the campus looks somewhat as if some mythical giant that was into modelling had acquired a lot of Hornby-type buildings from a giant Ancient Universities series and then, having arranged them nicely on its lawn, subsequently moved away, leaving it free for a passing university to occupy. It is weirdly like walking around a curated exhibit that happens to be teaching space. Nonetheless, the conference facilities were top-notch, so I adjusted. This was the running order for the first day:

Coins, Minting and the Economy in Late Antiquity and the Early Middle Ages, 29th April 2016

  • Alan M. Stahl, “An Introduction to FLAME”
  • Lee Mordechai, “The FLAME Project: Framing the Late Antique and Early Medieval Economy: An Overview”
  • Alan M. Stahl, “A Numismatic Introduction to FLAME”
  • Peter Sarris, “Coinage and Economic Romanitas in the Early Middle Ages (c. 330-720)”
  • Florin Curta, “Remarks on Coins, Forts, and Commercial Exchanges in the 6th- and Early 7th-Century Balkans”
  • Vivien Prigent, “A Dark Age ‘Success Story’: Byzantine Sicily’s Monetary Economy”
  • Marek Jankowiak, “The Invisible Part of the Iceberg: Early Medieval Imitative Coinages”
  • Jonathan Jarrett, “The Marriage of Numismatics and X-Rays: Difficulties with the X-ray-fluorescence-based Study of the Early Medieval Mediterranean Economy”
  • Richard Hobbs, “Hoards of Gold and Silver in the Late Roman Empire”

As you can see a lot of this first day was dedicated to explaining the project to an audience not necessarily directly connected with it (including, mirabile dictu, Peter Brown, though he didn’t stay around for my paper…), which involved explaining that it was starting with minting and production (because you can use any coin that can be identified as data for that), and that a second phase (in which they are even now engaged) would deal with circulation, as measured by where the coins actually wound up after leaving their mints. The questions that this raised were about what material, space- and time-wise, was included, but also about what questions the project was intended to answer, and I would have to say that we really only got answers to the former.

Alan Stahl’s paper was basically a summary of coinage history across the period and raised questions of tinier detail, but to all those that were of the form, “why were they doing that?” he raised the factor of user demand, which is indeed something people don’t think about much; lots of stuff was apparently usable as coin we don’t think should have been, but it must be we who are wrong there.

Peter Sarris’s paper stressed how many small ways the Empire had to alter the value of its coinage, whether by changing its weight or by changing the rate at which it could be exchanged for precious metal, for all of which the money-changers charged. Peter could speak of this with authority because of being nearly finished translating Emperor Justinian I’s new laws, which are now out.2 I still wonder how many of the practises described there were occasional preventatives rather than regular operation, but of course I haven’t read the laws yet. Here again, though, came up the theme of change that was and wasn’t acceptable to those who actually used the coinage; it seemed to me hard to reconcile the power attributed to the emperor and state and that attributed to the people, or really, the market, in this vision of Byzantium, and I still have to think that one out.

Florin Curta’s paper also touched on this by thinking that we have evidence of army pay-packets of large-denomination copper coins in military sites in the Balkans, but that smaller-value coins also got up there somehow in smaller numbers, the state and the market meeting here again and creating a different pattern doing so here than anywhere else. Andrei Gândilà suggested that fourth-century Roman small change was still in use in many of these sites so that the dearth of small denominations might not have mattered much, which of course as a factor threatens to unseat any of the deductions that one might try to make only from what was being minted

Vivien Prigent’s paper included his debatable (as in, I’ve debated it) belief that the term mancus refers to low-fineness Sicilian solidi, but also helped explain how those coins, about which I was also talking, as well as the inarguably slipshod small change of the era, came to be by setting them in the context of the short-lived relocation of imperial government to Syracuse in the reign of the justifiably paranoid Emperor Constans II, and the much increased demand for coin in which to make payments that the increased state apparatus there must have involved. Of course, Syracuse was an active mint before and after that, so until you can get quantitative representation into the sample, that wouldn’t show up in the video above.

Reverse of the same coin. It’s not from Syracuse, but it makes the point!

Marek Jankowiak was there to represent the Oxford-based Dirhams for Slaves project, and was consequently talking about apparently-imitative Islamic coins that we get in the region once populated by the so-called Volga Bulgars, which exist either as isolated singletons in huge batches all struck from the same dies; he explained these through the slave trade, which I might doubt, but I had to agree that the best explanation of a find record like that is that local production of coinage had suddenly to be ramped up at very short notice now and then, and maybe the best explanation for that is a bunch of incoming people you have to pay at short notice… Still, slaves might not be the only reason for that. His general emphasis on counting the imitative coins as part of the sample is something I deeply agree with, however; but again, how could a project set up with FLAME’s premises (identifiable mints) do that? By being very vague about origin location, was one answer, but that means that the dots in that video above are sometimes artifical and sometimes historical, and to read it you have to know which…

Then there was me, and of course you know roughly what I was saying, which was, “we tried doing this analysis by XRF and it doesn’t work so don’t believe people who do that”, but I’m afraid the reactions it got were about equally split between “well yes, don’t do that then” (though the relevant person did then offer me use of a cyclotron if I could sort out the insurance…) and “man I gotta try that now”, so I’m not sure it really had the effect I was after!

All of this had been interesting to me but in some ways the last paper, by Richard Hobbs, was the most so, and not least because it showed again how small the difference can be in terms of results between the dedicated lone scholar with a personal project (and, admittedly, the British Museum behind him) and a massive well-funded team effort like FLAME. Hobbs had been assembling a database of Roman precious-metal hoards, coins included, which he was comparing substantially by bullion value, but in the course of doing so had noticed many weird things, such as:

  1. During the third-century crisis, unsurprisingly, there were hoards buried all over the Empire, especially on the frontiers, but during the period 395-411 it’s almost only the coasts of the English Channel that show them.
  2. Only Gaul really hoarded silver plate in the third century, and not many more places thereafter until a generalisation of the habit during the sixth century. Did coinage not work as well in Gaul as everywhere else, or something?
  3. Despite the numerous wars there, fifth-century Italy either didn’t hoard stuff or always recovered it (or we haven’t found it, but that seems unlikely; it’s not as if hoards from other period of Italian history are unknown)….

While a lot of this is down to detector bias, for sure, there is something here about variation of response to crisis (and to wealth!) across regions that we would struggle to see any way, but it’s still quite hard to interpret. One thing is that we are looking at non-recovery, not necessarily hoarding per se; we only have hoards whose owners didn’t come back for them, and that’s important. But still: what does it all mean? That is is often the result that assembling a lot of data gives us, isn’t it?

All of this was therefore good for getting conversations going, but it was made additionally surreal by the fact that one of the attendees, Stefan Heidemann, had been prevented from actually attending by a series of small disasters. Not deterred, he was therefore present by Skype from Germany, but not on the main projection screen as might normally have been done, but on a laptop that was placed where he could see the screen, or on a trolley so that his field of view could be changed between presenters and audience. The latter meant that his window on us had to be rolled about like a trolley, but this more or less worked, and the link somehow stayed up throughout. In the final discussion people were wandering up to Stefan’s wheeled avatar to say hi, and I couldn’t shake the idea that we were looking at the future here somehow, as if the gap between this and an entirely virtual presence of a digital-only academic was just a matter of degree. It made things odder…

Florin Curta delivering his paper at the FLAME Conference

This is Florin Curta presenting, but, if you look carefully, in the centre of the table in front of the screen is a laptop, face towards the screen. If you could somehow see that face, it would be Stefan Heidemann’s…

Anyway, all of this had meant that Stefan, who had been supposed to be speaking on the first day, actually led off the second, whose running order was thus:

FLAME, Phase 1: Minting, 30 April 2016

  • Stefan Heidemann, “The Apex of Late Antiquity—Changing Concepts of Monetarization in the Early Islamic Empire”
  • Lee Mordechai, “The FLAME Project: Framing the Late Antique and Early Medieval Economy. Details and Future”
  • Andrei Gândilà, “Legacy of Rome: Money in the Early Byzantine Balkans and Asia Minor”
  • Jane Sancinito, “The Mint at Antioch: Disruptions in the Fifth Century”
  • Luca Zavagno, “Coinage from the Eastern Mediterranean: an insular perspective (ca. 600–ca. 750 C. E.”
  • Tommi Lankila, “Coinage in the South Central Mediterranean in Late Antiquity and the Early Middle Ages”
  • Paolo Tedesco, “The Political Economy of Accomodation and Monetary Circulation: the case of Gothic Italy”
  • Ruth Pliego and Alejandro G. Sinner, “Minting in the Iberian Peninsula 350–725”
  • Merle Eisenberg, “Money as Governance: The Burgundian Revolution of 500 C E.”
  • Jan Van Doren, “Merovingian Gold Coinage in the Low Countries”
  • Rory Naismith, “From Feast to Famine and Back Again: Mints and Money in Britain from Fourth to the Eighth Century”
  • Round Table chaired by Cécile Morrisson

As may be evident, this second day was much more about project participants presenting their data. Stefan, however, was again demonstrating how much a lone scholar could do with his own database, as well as a sharp knowledge of sharia law. He emphasised how devolved jurisdiction over Islamic coin could get: while gold was controlled centrally where possible, silver could be run at provincial level and types and identification of authorities vary there, and we are quite unclear about who issued copper-alloy coinage as sharia doesn’t consider non-precious-metal to really be coin, rather than, I suppose, tokens; imitative production to answer demand thus probably happened rather a lot, as indeed we have seen here with the Arab-Byzantine coinages of Syria and Palestine. Their circulation was very local, however, so for any long-range transaction small change was made by cutting up legitimate coin, to generate the fragments we have so many of from Scandinavian hoards, which were presumably counted by weight. Clearly Stefan could have gone on for longer—I think he was trying to summarise a book here—but even what he was allowed to say left me a lot clearer about the systems behind what I have seen in the material.

Once we got into the actual project members’ papers, however, it becomes easier to be economical in the reporting. Lee Mordechai helpfully emphasised many of the difficulties with the project I’ve raised above, but hoped that the second phase, when findspots and hoards were more fully integrated, would help clean things up a bit. He also emphasised that there was far more data out there than they were using in the form of the trade, whether just harvesting eBay (for which, of course, software once existed…) or trying to gather all auction catalogues (and eliminate duplicates?). So how selective is their data, one might ask?

Andrei, meanwhile, painted us a picture of circulation in the Balkans (despite the project not being onto that yet) that showed a tremendous mixture of coinages from different Roman and Byzantine eras being used together; how were their values calculated? If they were strictly face-value, why change the size of the coins? If they weren’t, why tariff coins against each other as Constantine IV was evidently doing when he issued new large ones?

Copper-alloy 20-nummi of Emperor Constantine IV struck at Constantinople in 664-685, Barber Institute of Fine Arts B4304; note the small M, apparently indicating that this big 20-nummi coin was equivalent to an old small 40-nummi one like the cut-up bit above

This paper and the discussion after it provoked me to write one of my own I’m giving in China in a couple of weeks, so I’m grateful, but it was a sharply divided discussion. Peter Sarris believed strongly that coin was basically moving by weight, in which case it seems stupid for the Empire to have issued coins of the same face value in larger sizes than previously; but this it repeatedly did. I tend more to believing in face value, seeing the size increase as essentially a PR exercise, which Andrei also suggested, and as others pointed out big and small coins did get used together, whereas if their value was different you’d expect only the big ones to be hoarded, but I admit it’s not unproblematic. Andrei wondered if old coin was treated as being equivalent to the piece of current issue that it weighed most like, and that seems murderously complicated, but it might be possible.3 Jane Sancinito was a Parthian specialist temporarily employed on sorting out the coins in the archive of excavations from Antioch that Princeton happens to have, which is what she told us about.4 Luca did roughly the same job for the Eastern Mediterranean island zone, as you’d expect, but again was able to emphasise how long-lived even the most basic small change could be, with Syracuse issues lasting a century or more in Crete and so on, and the overlap between supposedly conquered zones and still-imperial spaces in the wake of Islam, as has been said here, potentially telling us something quite important, but hard to specify. Paolo Tedesco was trying to link coin use patterns to the question of how ‘barbarian’ soldiers were settled in Italy that has generated so much scholarship, but it turns out that the coin finds don’t help, or at least suggest that very little money moved from the capitals to the south, as if everything there was sorted out locally.5 The two Hispanists summarised Visigothic gold coinage but noted that there was at least some silver and copper coinage too, which is still contentious among Spanish numismatists for some reason; this wasn’t news to me but I expect it was to others.6 Eisenberg was mounting an attempt to link the few Burgundian coins we can identify to known events that might let us date them, but wasn’t helped by the fact that the Burgundian laws refer to several sorts of coin we either haven’t got or can’t identify, and as Helmut Reimitz pointed out, were not even necessarily issued for the kings! The paper did provoke the useful announcement from Cécile Morrisson that all the Bibliothèque Nationale de France’s collection of Merovingian coinage is now online, however, which may be very useful to some people. Van Doren reminded us how much coinage the late antique Low Countries produced, almost all apparently for North Sea trade since it barely turns up in France. Lastly Rory Naismith did much the same exercise for Britain, but this involved calling into question the whole concept of mint as more than the identity carved onto a pair of coin dies, and in most British cases we don’t even have that, so how can these coins be attributed as a project like FLAME would want? The British record is however massively distorted by the huge volume of fourth-to-fifth-century Roman hoards; at a later point in the conference Alan Stahl revealed that they now had that data in FLAME, but its effect was simply to drown out everything that wasn’t British in whatever query one ran, so they’d had to exclude it again! What do you do when your evidence prevents you using your evidence? The round table addressed a lot of these questions, but it would be hard to say that it solved any of them…

Many of the same questions came up again in a final workshop the next day, along with many suggestions for how to get truer or more realistically qualified results out of the database. I think that this probably was useful to the project team, and maybe was the big point of bringing us all there; there as much can’t-do as can-do in their responses, but the discussion as a whole left me much happier than I had been going in that all this data would probably be more useful to have than not, and could answer many questions if flagged and curated with suitable cautions and references. (And indeed, work has continued and many useful things that were talked about at this meeting seem to have happened.) The labour still seemed immense, however, and it is perhaps not surprising that, although at this stage there was talk of publishing this conference, a journal issue, and many other things, in the end I’m not sure that anything has come of it except the still-developing database, which remains on closed access. The project director has moved on and now works on late antique environmental history; none of his publications seem to have come from the project, and I can’t find any signs that others have. Even the site’s blog is now inaccessible in full. One wonders how long the website itself will survive, and then what all this money and time will have been spent on. I suppose the message is: data is great, and could potentially change everything, but while they were right in these discussions to say that this dataset could answer a great many research questions, it may have turned out that having no questions has sadly doomed them to having produced no answers. Maybe this post can be an encouragement to others who do have questions to see if the FLAME database can answer them! But you will have to ask them first!

I didn’t organise, I merely report, but I also note that among the people on the All That Glitters project for whom this would have been closer to their research area than it is to mine, two are women, so more women certainly could have been invited.

Seminars CXXV & CXXVI: differing data from the East

In the continuing attempt to clear some of my ridiculous blogging backlog before the new academic year starts in the UK, I am sadly going to pass over James Palmer‘s paper at the Earlier Middle Ages Seminar in London in February this year, not because it wasn’t interesting but because Magistra has already covered it, and this brings me back to Oxford. As we saw with the last of these posts, on a Monday when it seems to be required, it’s possible to attend both the Medieval Archaeology Seminar and the Medieval History Seminar here as there’s half an hour’s grace between them, and the 27th of February was such a day, as a remarkably complementary pair of papers were being given across the two. The first was “Between the Carolingian West and the Byzantine East: fortified élite settlements of the 9th and 10th centuries AD in Central Europe”, by Dr Hajnalka Herold and the second was “Dirhams for Slaves: investigating the Slavic slave trade in the tenth century” by Dr Marek Jankowiak.

The hilltop over which stretches the site of the Gars Thunau hillfort complex, on what seems to have been a horrible day when whatever satellite Google gets its pictures from flew by

I first heard Hajnalka speak at the Kalamazoo of 2010, as is duly recorded here indeed, and this meant that some of what she was presenting was not new to me, as in order to set things up she had to talk us quickly through a number of sites which are not exactly household names in the West. (I sympathise with this: it frightens me how few people have any clear idea where Girona is and no-one but me and by now you has heard of Vic or Urgell but at least, bar the latter perhaps, people can usually spell the names from my area once they’ve heard them.) The sites are scattered across a zone shared between what is now Austria, Hungary, the Czech Republic and Slovakia and the state of publication and excavation is very various but, starting especially from Gars Thunau in Austria, Hajnalka is trying to fit these various, and variously-sized, power centres into wider frameworks, and as you can tell from the title of her talk is willing to look quite widely to find out what the builders thought they were doing and what kind of position they’d achieved that meant they could do it. The zone lay between empires, Frankish, Byzantine and at times Bulgarian, and any of these might be found pushing their influence into it at a given point in the period. The two former especially competed in the mission field, and had done for some time of course, which makes it particularly tantalising that many of these sites contained churches, in fact in the case of Mikulčice, in Moravia, nine churches, and in Zalavár in Hungary, a huge one which seems to have been of a size and complexity to rival pretty much anything in the West of the time, and a number of smaller ones on neighbouring patches of sandy ground. A Salzburg text called the Conversio Bagoariorum et Carantanorum claims that this was the work of the Archbishops of Salzburg, but it would be nice to know which phases and when, if that’s even true…1 (I note that further south, in Croatia, there is dispute over whether the Aachen-like complex at Zadar was put there in emulation of or in reaction against Carolingian ecclesiastical pressure.2)

It’s easy initially to see what unites these complexes: firstly, they’re all fortified settlements and secondly, where there is good dating evidence, they seem to have all got new ramparts at the close of the ninth century. That’s more or less where the similarities end, however: the technologies of building, the size and focality of the complexes and likely, therefore, their apparent purposes all differ site to site. Furthermore, with only archæology to go on (the few written sources here, Conversio included, don’t help very much at all putting together a big picture) it’s hard to guess at who was in charge of any of these places or how they were supported.3 There are aspects that look familiar from the West: all these sites showed evidence of craft manufacture (though glass and precious metal were confined to the biggest ones), of space for Christian worship and for burial (not obviously non-Christian, if there is in fact any such thing archæologically-speaking) and of social stratification. On the other hand, these sites were not emporia, their trade links as so far testified in the material culture were thin and almost incidental, although quite farflung, there’re almost no coins and so forth. (More digging could change this in almost all cases, however.) The links that we do see, however, run both east and west, and this is clearest in the dress hinted at by the burial evidence: broadly, Hajnalka sketched, we’re looking at a set of sites at which the men dressed Frankish and the women dressed Byzantine, high-status persons in both cases of course and not without exceptions. The rank and file (and indeed the slaves who must have been there) are less distinctive. So the big message that Hajnalka had was that, although it is very easy for Westerners to look at a scenario like this (or that at Zadar, as noted above) and see a reaction to the Carolingian and Ottonian Drang nach Osten, in which local élites funnel luxury goods from the pressuring western empire and use that wealth to build up structures against it, when you’re on, and indeed in, the ground at these places the Franks were very far from being the only players for these people’s attention and imitation.4 But there is much more to be done to work out what the people in question were actually up to, in political or other terms, and we can hopefully look to Hajnalka to do some of it!5

Silver dirham of Caliph al-Walid I from Tashkent, struck 713, found in Latvia

The Medieval Archaeology seminar has lately taken to laying on tea and cake afterwards, which is very welcome and made it much more possible to pay attention to Marek Jankowiak after the brief trot to All Soul’s College. My notes indicate that he had an excellent set of visuals to back up his argument, about which sadly I can remember nothing, but those of you who may be setting up to see what must be a related paper at this term’s Institute of Historical Research seminar are in for a treat, at least. Here I can only recreate from my notes alas, and they tell me that what was principally at issue here was the absolutely huge preservation of Islamic silver coinage in Northern Europe. Dr Jankowiak wanted to get us thinking about how they had wound up there and what was moving in exchange. This first entailed a more detailed analysis of the finds than I’ve seen before, noting that particular areas receiving dirhams seem to have blipped in and out of the record at different times (except in Gotland where deposition was pretty continuous), and that the area providing them seems to have shifted from Iran to the Samanid Emirate at Khorasan over the tenth century, with Iraq hardly showing up and Spain not there at all. These were supplemented by imitations of such coins from the Khazar and Bulgar areas, again shifting from one to the other over the tenth century. By a series of rather unlikely calculations, Dr Jankowiak hypothesized that, if 75%-80% of this exchange was being paid for with slaves (a figure whose basis he did not explain) then we might be thinking of an export of 30,000-60,000 human beings over the century, a few hundred every year, but that that would not include exports to the West which, however they were going, were obviously not being paid for in a medium so readily hoarded. Identifying the slaves archæologically, given that they were exported and acculturated, is basically impossible but just because of the numbers involved Dr Jankowiak wound up developing a picture in which entire peoples, small tribes or whatever, were basically hoovered up and fed into this market by their more powerful neighbours, and thus suggested that the reason for the sudden boom in fortification in Central Europe in this era is because those who could be wanted to be on the rich side of this process, not the poor side! He saw in this the origins of settlement nucleation in Poland, especially, and suggested that we should perhaps see the lesser hillforts not so much as fortifications but as slave corrals with garrisons via a chain of which the unfortunate human goods were convoyed eastwards, a system out of whose profits new states might bloodily grow.

Naszacowice hillfort, Southern Poland, from the air

At that point, of course, these two papers came directly into conflict. For example, in Dr Jankowiak’s Southern Poland, apparently, many of the forts (and there are many there, but of course only a few have been dug well enough to provide dating evidence) show destruction layers. Is this because Poland was developing a central power that had to suppress these places? In that case, one might equally expect the Polish forts to be refuges, something that Dr Jankowiak ruled out due to the very small number of finds there that suggests to him only temporary occupation. But, many of these sites were dug (when they have been) a long time ago and it’s debatable what would have been found in such excavations and whether occupation, rather than just ‘artefacts’, would have been recognised. Anyway, the point of refuges surely is that they’re only temporarily occupied. And so on. These are issues I’ve brought out myself, but plenty of other people also had objections, about the neglected contribution of the fur trade (better seen in animal bone evidence further east than here, according to Dr Jankowiak), about the effects on prices of this influx of money that likely make a constant figure for the tenth-century slave economy problematic and (of course) about the hypothetical mathematics, it wasn’t even me for once. I did, however, ask about the hoards in Scandinavia, to wit: why on earth is there deposition on such a scale here without retrieval? Because if you have a hoard, one thing you can say for sure is that the owner didn’t come back for it. Was Scandinavia then even less stable than Central Europe’s slave-grounds? Dr Jankowiak thought that the hoards might be sort of treasure banks that were accessed on a small scale only, an increasingly fashionable idea, but if so, what the finds evidence seems to be showing us is an Eastern Scandinavian economy that brought in a great deal of coin but seems then to have considerable difficulty doing anything with it, which must make it worth rethinking whether this was in fact about getting rich. So there was a lot of debate. All the same, there is this much that cannot be gainsaid here: we know there was a slave trade, some of this money that we have found must have been paid for slaves, the changes in its deposition probably do reflect a variation in the availability of goods that Islamic merchants would pay for and so there’s a certain horrible plausibility about some of the mechanisms Dr Jankowiak laid out here, even if not whether the forts are part of those mechanisms or not. With that much accepted, if I can bring George Bernard Shaw back in again, we may just be haggling over how much was involved…


1. This intriguing but allusive text was edited by Herwig Wolfram as Conversio Bagoariorum et Carantanorum: das Weissbuch der Salzburger Kirche über die erfolgreiche Mission in Karantanien und Pannonien (Wien 1979) and he seems to have spent a long time since then trying to figure it out, resulting in idem, Salzburg, Bayern, Österreich: die Conversio Bagoariorum et Carantanorum und die Quellen ihrer Zeit, Mitteilungen des Instituts Österreichs für Geschichtsforschung Ergänzungsband 31 (Wien 1995). This is not my area and I’m not going to pretend to have read either of these (I’ve seen quotes from the former), but they exist should you want to.

2. Here I know what I know from Miljenko Jurkovic and Ante Milosevic, “Split. Croatas y Carolingias: arte y arquitectura en Croacia en la alta edad media” in Jordi Camps (ed.), Cataluña Carolingia: arte y cultura antes del Románico (siglos IX y X) (Barcelona 1999), pp. 165-170, transl. as “Split. Croats and Carolingians: art and architecture in the early Middle Ages”, ibid. pp. 501-504.

3. One possibility, which I understand from Hajnalka may indeed be feasible at some of these sites, could be the kind of analysis of animal bone that Leslie Alcock was able to get done at the very early medieval Welsh site of Dinas Powys, and which showed that the cattle they were getting there were all young animals, not the spread of ages or mostly mature beasts that you’d get from a natural herd, thus showing that the occupiers of the site were probably receiving tribute: see his Dinas Powys: An Iron Age, Dark Age and Early Medieval Settlement in Glamorgan (Cardiff 1963), reprised and updated in his Economy, Society and Warfare among the Britons and Saxons (Cardiff 1987), pp. 5-150 where the animal bones are discussed pp. 67-82.

4. For a round-up of the post-Carolingian view of this general area see Matthew Innes, “Franks and Slavs c. 700-1000: the problem of European expansion before the millennium” in Early Medieval Europe Vol. 6 (Oxford 1997), pp. 201-216.

5. And indeed since this paper took place she has done, in the form of “Fortified Settlements of the 9th and 10th Centuries AD in Central Europe: Structure, Function and Symbolism” in Medieval Archaeology Vol. 56 (Leeds 2012), pp. 60-84, DOI: 10.1179/0076609712Z.0000000003. I’m not quite clear if this is actually out yet: the journal’s website says the current issue is Vol. 57 (2013) but only gives indices for up to Vol. 55 (2011). In either case I must thank Hajnalka for sending me a preprint version ahead of publication.
