Life seems at the moment determined to carry me relentlessly between cities, but I have plenty of good reasons to be in Cambridge at almost any time, and so when I learnt that on 17th March the Chadwick Memorial Lecture would be given there by none other than Professor Emerita Wendy Davies, it seemed rather as if a number of birds had queued up in front of my metaphorical mangonel. This was not least because her title was “Water mills and cattle standards: probing the economic comparison between Ireland and Spain in the early Middle Ages”, which may not sound so great in a detached way but Wendy is a person who can give a fascinating seminar paper about a single charter formula; her fans, among whom I freely number myself, must have known this would be good. And so it was. While a comparison between Spain and Ireland in the early Middle Ages may not seem that intuitive, it’s surprising how well it works (as long as you stick with Northern, Christian, Spain anyway). For example, Ireland is famous now for medieval mills; Spain has fewer known in archæology (and much less archæology generally, though there is apparently hope for a dig of a Leonese market site which would hopefully be fascinating) but does have lots of recorded disputes over them; both countries are also famous to medievalists for using cattle as currency (even if some of us disagree as to their value), and though there are other similarities these were the ones Wendy decided to use as wedges to open up the nature of early medieval societies a bit.
There are also differences. You won’t see documents like this in Ireland, but on the other neither will you find 50,000 ringforts in Spain, and though there are forts, very few have been dug. The climates obviously differ, though by less than you might expect in Atlantic, misty Galicia. Nonetheless, Wendy also detected similarities in the persistence of tradition, both regions having seventh-century law active in their courts till much later, for example, and using sculpted stones as boundary markers; in transactional language (and here, I have to admit, I find my notes less convincing than I found the lecture); in the importance of cereals, which is to say considerable but far from total, and in the growth of this cultivation over the ninth and tenth centuries (though that, I think, you would see in most places); in valuation, which was sometimes by cattle and otherwise by metal or other goods (in Spain the metal was notionally coined silver but only in Catalonia, which Wendy as usual disclaimed, was that coin actually available), with massive variation;1 and therefore in the exchange of unlike things, which means that there was some kind of commercial infrastructure in both places. Again, where not, you might wonder, but the evidence we have to demonstrate this is weirdly similar in its difference in these two places compared to elsewhere, where it is usually simply money (though that, as we know, need not always imply trade).
Both also seem to have gone through some parallel developments in the Viking era, which is odd as although there certainly were Viking attacks on Spain as we have before here discussed, some of the things that are usually explained by Viking influence in Ireland also happen in Spain, apparently for other reasons: a boom in the use of silver bullion as currency (eventually as coins in Ireland but as argentazas, which no-one is sure about,2 in Spain, Catalonia again apart), a new development of certain urban locations as population, military, administrative and economic foci (in Ireland Dublin and Waterford, in Spain most obviously León), and burgeoning exchange relations. Several of these are wider European phenomena, in which case their national explanations might need questioning… As Dr Mairé ní Mhaonaigh pointed out in her response, of course the Book of Invasions tells us Ireland was settled from Spain anyway, and there are probably more similarities to be found yet, but in this respect I think what I took away was one of my old favourite sentiments, hurray for deviation and variation. Because, in the things that are not quite the same lies a shortage of variables that means we can sometimes actually pin down the reasons for things, and that’s really rather what we’re here for, isn’t it?
