Apparently I was mainly thinking about coins in late spring of 2016, as I seem to have stubbed a lot of posts in a row about numismatics. This is the third and last of them for a little while, which was occasioned by teaching the rise of Islam for my first-year module Empire and Aftermath at Leeds. I like to do this using the coinage as the key primary evidence, because I can and because, as has been observed by greater scholars than me, basically all the Islamic textual evidence for the actual seventh-century spread and conquest is post facto, written deep in hindsight, while the limited contemporary evidence we have is either largely written by outsiders and deeply hostile or written by non-Islamic insiders whose perspectives were unhelpfully local.1 Getting a picture of what was going on over, say, all of Syria, Palestine and Iraq between about 650 and 700 beyond the rough succession of caliphs and some key battles, is therefore very difficult, and even that can be tricky; consider, after all, that this is the period during which Shi’a Islam separated from the Sunni branch and each side’s historiography has a quite different view, not just about which caliphs were legitimate, but even about when they ruled and whose relations they were.2 The coins don’t settle those questions (though they open up others about faction and segmentation3) but they are at least directly contemporary sources from inside the territories newly run by Islam. That is, assuming that we can correctly date and attribute them. And that’s where the fun starts, of course!

The biggest problem here is that at first, the new authorities of Islam basically imitated the coinage they found in the areas they took over, by way of maintaining tax systems and basic economic exchange. It wasn’t until the 690s that Caliph ‘Abd al-Malik (of whom we have heard before here) unified the various disparate post-Byzantine and post-Persian coinages he now had in his realms. Up to that point, his territories ran a pseudo-Byzantine gold coinage, a pseudo-Persian silver one and a whole scatter of pseudo-Byzantine and some pseudo-Persian copper-alloy ones.4 Most of the copper-alloy, at least, carry little or no identifying information. It is generally assumed that there was a transition from things more or less like their originals, through things less like them with Greek rather than Latin legends to things even less like with Arabic text on them to the so-called Standing Caliph coinage and then unity, but actually, despite painstaking analyses of what was being restruck onto what, what is found with what and how weights might have changed down an utterly hypothetical declining scale, as I’ve said here before, we still can’t honestly say that all of those different sorts of coin and a whole set of ‘imitative’ issues weren’t being struck alongside each other, by issuers ranging from the state through town councils to local blacksmiths.5 The closer one gets to the latter picture, the more informative the coins seem about how the process of Islamic takeover might have looked on the ground, which is to say, more or less like a prolonged vacation by state authority, saving occasional visitations, and then some episodes of suddenly-tightening regulation, maybe only in some places.

Some day I hope to write about this, as I’ve said, but today I just want to write about coins like the one above. You see, one of the exceptionally problematic aspects of the coin evidence for a normal tale of military conquest and take-over is that, to all appearances, imperial small change continued to arrive in the ‘conquered’ territories for some years after their ‘loss’ by the Empire. This is really obvious, because the issuing emperor changed at about the right point; the supposedly-crucial Battle of Yarmuk that effectively debarred the Byzantines from Syria took place in 636, as near as we can be certain, Emperor Heraclius died in 641 and after some confusion his grandson Constans II succeeded, and Constans’s copper-alloy coins are frequent finds in Syria, arriving, it seems, up till about 655 (though dating Constans’s coins relies on those guesses about weight that I myself don’t trust).6 So why was the Empire still shipping in or selling to its supposed enemies? Part of an answer may lie in these coins, which are found very frequently in Syria and nearly as often in Cyprus, but don’t really occur elsewhere in the Empire.7 They look very much as if they were being struck in Cyprus for use in the now-Islamic provinces; it has been argued instead that they were being made in Syria and exported, but if so they occur more than any other sort of probably Syro-Palestinian issue in the island.8 By the 670s the Byzantine Empire and the Caliphate had even agreed that neither of them could effectively take Cyprus off the other, and so there was established a condominium in which their two sets of representatives shared the island’s taxes; one wonders how many other areas might early on have had some such fuzzy arrangement in which the Empire grudgingly recognised the conquerors as new quasi-independent governors but still demanded recognition of its dominion in the form of tax, and then that situation got wiped out of potential record by changes in the 670s to 690s.9 If such areas had made a pact with the Caliphate, both sides might have quite happily claimed them as their own without either really having much control over them until they made an effort to assert it.

But there is a numismatic problem with such a hypothesis! And that problem is, these coins do not bear a mint-mark indicating Cyprus like the authentically-Cypriot one above (KVP or KVPR for Kypros), but carry the unhelpfully unspecific legends of the regular issues of Constantinople. And yet they do not look like the contemporary metropolitan coins of Constans II. Furthermore, just to confuse matters, coins that did carry the Cyprus mint-mark were almost certainly being made in Syria, imitating the earlier issues of Heraclius and Constans II!10 So, a number of options open up, one being that these sort-of-regular coins are actually somehow imitative or unofficial (whatever those words really mean in a situation like this), perhaps because there was a mint on Cyprus, potentially running under Islamic control and making what those authorities thought real coin looked like, or otherwise, that Constantinople was making an export-standard copper-alloy issue that was then being shipped to Cyprus for distribution into Syria.

I’m not sure which of these hypotheses I find less likely, to be honest: the former requires effective forgers who nonetheless didn’t fully understand the system into which they were passing coin, and who made their coin larger and neater than the regular issues they were imitating, in which case what was the profit? and the latter seems like an administrative headache with no clear gain except keeping Cyprus slightly further from fiscal independence. But the latter also incurs numismatic disdain because numismatists really try to avoid hypotheses in which a single mint is issuing distinct sorts of coin of the same standard at the same time. They will even mount hypotheses on the basis that that couldn’t happen.11 Now, I’ve disproved a couple of these already in my small way, but in this instance I’m not so sure it needs doing; although we as a discipline don’t usually admit it, it’s very unclear as to why the Empire put mint-marks on its copper-alloy coinage. It’s often assumed that it was for accounting and authentication purposes, either knowing how much a mint was making or being able to track dud coins back to their issuing mint, but in the former case the only place you could do that was surely at the mint itself, before dispersal into currency, in which case why bother marking them? and in the second, it’s very peculiar that it was done on the effectively worthless metal of the small change but not on the highly-protected gold of the solidus, and no-one ever tries to explain that.12 Whatever the reason was, though, it’s not hard to imagine the mid-seventh century involving circumstances in which that just didn’t apply. Either way, the coins are telling us something about what’s going on here that a purely textual approach will never disclose; but numismatics also has to shed an assumption or two before we can do the kind of work with it that opportunities like this make possible…
