Nielsen, Oxford 2005, a product of the Copenhagen Polis Center, the Inventory identifes, catalogs and describes over 1000 ancient Greek poleis from the archaric and classical periods of c. 650-325 BC. It is a seminal body of work, 10 years in the making, produced by a large, cross disciplinarian team of scholars.
