Walking around Berlin, you can’t help notice the advertisements for a new show at the Pergamon Museum, called ‘Uruk Megacity‘. While you might forgive the curators for trying to lure visitors, the question is whether Uruk was really a city, let alone a mega-city. The walls themselves at the greatest expanse in the fourth millennium encompassed 6 square kilometres. Huge? More like a country town. Estimating population is a bit like divination, so estimates range from 20,000 to 50,000 (the top end is little fanciful). A decent town, perhaps, or even a small city. Except that this is the total population of the whole city-state of Uruk, which was really a rather modest affair. At a stretch, you may want to argue that by comparison with other places, it counts as a city, where most of the few centres were around 3000 each. But ‘mega-city’ is really pushing it. Then again, ‘Uruk, Megatown’ doesn’t quite have the same ring to it.
