Before we dive into the evidence, I want to speak briefly to the nature of the evidence for these topics. “Historian” is often an odd sort of field because while there is a core discipline and skill set that basically all historians are going to have (focused on reading texts critically and assessing arguments and evidence), beyond this almost all historians end up acquiring other skill sets, often from other fields, depending on what they are investigating. I, for instance, work on military history and so I need to have some mastery of military theory, whereas an intellectual historian might instead have some training in philosophy.

It is thus relevant that over the past half-century or so, it has so happened that effectively all ancient historians have had to develop a strong grasp of archaeological data; we don’t all necessarily learn to do the excavation work, of course (that’s what archaeologists do), but pretty much all ancient historians at this point are going to have to be able to read a site or artifact report as well as have a good theoretical grasp of what kinds of questions archaeology can be used to answer and how it can be used to answer those questions. This happened in ancient history in particular for two reasons: first, archaeology was a field effectively invented to better understand the classical past (which is now of course also used to understand the past in other periods and places) so it has been at work the longest there, but also because the sources for ancient history are so few. As I like to say, the problem for the modern historian is taking a sip of meaning from the fire-hose of evidence they have; but the challenge of an ancient historian is finding water in the desert. Archaeological data was a sudden, working well in that desert and much of the last two decades of ancient history has been built around it. Other fields of history are still processing their much larger quantity of texts; why dig so deep a well when you live next to a running river?

The result, in ancient history, has been what I tend to refer to as “the revenge of the archaeologists”. Not, mind you, revenge on medievalists, but in fact revenge on a very specific ancient historian and classicist, Moses Finley. Moses Finley was, from the 1950s to the 1980s, one of the most prominent classicists and his work touched on many fields, including the study of the ancient economy. Finley, writing in the 1960s was generally skeptical of the ability of archaeology to provide useful answers about the ancient economy (he preferred to understand the question by probing the mentalities of the Greek and Roman elite). Archaeology, Finley thought, was frequently over-interpreted and could never give a representative sample anyway; as he quipped in his 1965 article “Technical Innovation and Economic Progress in the Ancient World”, “we are too often victims of that great curse of archaeology, the indestructibility of pots”, a line for which, as far as I can tell, he is still quite unforgiven by some archaeologists.

As if in response, the archaeologists have spent the subsequent almost-six-decades proving again and again the tremendous value of their discipline by, among other things, utterly burying Finley’s The Ancient Economy (1973) under a mountain of archaeological data. It turns out the mentalités of aristocrats who largely hated merchants were not a good barometer of the activities of those merchants.

But you may now guess how this is going to play out in the discussion of Late Antiquity. The ancient historians come to the question ready to think in archaeological terms and ask what archaeological data can do to clear up these questions. Scholars of Late Antiquity trained as medievalists on the other hand, may or may not be well versed in archaeological methods or data (to be clear, some medievalists very much are versed, including prominent voices on the “change and continuity” side of this debate! But it is also very possible to be a “pure text” medievalist in a way that I don’t think I know a “pure text” ancient historian younger than sixty) because their field has not been forced, by dint of the paucity of sources, to revolve so heavily around archaeological data and because the archaeological data on the Middle Ages is not yet as voluminous as that on Classical Antiquity.

As I noted in the first post, beginning in the 1970s, what James O’Donnell calls the “reformation in Late Antique studies” launched a long overdue reassessment of Late Antiquity and the impact of the Fall of Rome – what we’ve called the “change and continuity” argument. I bring up all of this to note that the “counter-reformation” – what we’re calling the “decline and fall” argument – that really emerges beginning in the 90s is in many ways an extension of the “revenge of the archaeologists” in Classical studies (and especially the ancient economy) into the field of Late Antiquity. Indeed some of the scholars are the same (e.g. Willem Jongman) and many of them enter the debate on Late Antiquity as an extension of the debate about the Roman economy (in part demanding that “change and continuity” Late Antique scholars acknowledge things now generally considered “proved” by ancient historians about the earlier Roman economy).

In my own experience, particularly in more informal conversations, the methodological difference that interaction creates between ancient historians – for whom it has long been almost entirely settled that in a “fight” between archaeological evidence and effectively any other kind, the archaeological evidence “wins” – and medievalists for whom archaeology is a much less central part of their method (in part because their textual sources are more extensive) can lead to situations where the two sides of the debate talk past each other.

But when it comes to questions of demographics, economics and the conditions of life for the sort of people who rarely figure in our sources, archaeological evidence – although it is often incomplete and hard to interpret – offers the possibility of decisive answers to questions that otherwise would have to live entirely within the realm of speculation.
