I picked up this collection from my local library. It’s a series of short essays, edited by John Rich, from archaeologists and historians on cities in late antiquity (as the name would suggest). As one would expect, this essentially tracks changes in cities as the Roman empire declined. This is a mixed bag of behaviours depending on region and time period – the essays are thus divided by regions.
Generalizing is difficult, but we read about the continued prosperity of cities in Africa; the decline of the Curiales (a sort of oligarchic council) than ran the settlements, replaced by the church in Gaul and the later Byzantine governors in the Danube; the discontinuity or continuity of towns in Britain*; the use of classical art styles by the Lombards in Northern Italy.
There’s a lot of detail in here, but it still feels like its only scratching the surface. It’s not the most up to date volume (from 1992) or the most readable (more down to the number of authors across the chapters rather than a lack of quality) but it does show the variety of interesting threads that come out of this period of history.
