Our latest from Christie's is a 1st century Roman copy (I've always wondered how they know it's a copy) of a 4th century B.C. Greek piece of some philosopher ... in addition to the official description on this one, folks might like to read a piece from the New York Times about the collection whence this (and most of the previous pieces) comes. [note in passing ... what I find very interesting about much of these pieces is that, unlike many other auctions, most of them seem to have been published]
