Interesting. There is also an element of this kind of 'savagery' in much of the early travel writing, well into the early modern era, perhaps prompted also by translations of Herodotus (& Aristeas) and especially, Ptolemy (another summary of ancient texts), and Roman concerns about Scythians and Gauls. Conquests of the East, Africa and the New World thereafter would incldude similar stories of canibalism among the 'other'. Not sure how much of it is true. Travels of Sir John Mandeville are a fun read, and reflect similar accounts by authors who didn't actually witness much of what they wrote. But I digress. Greeks must have been delicious.
