According to page 96 of Sedley's "Lucretius and the Transformation of Greek Wisdom," a bust identified as Zeno of Sidon was found in Herculaneum near the scrolls.
I have apparently been slack during my studies and I cannot identify any of the pictures I have saved as being that of the bust of Zeno of Sidon, and his wikipedia page does not have a photo either. This is a situation that ought to be remedied both here at EpicureanFriends (where we ought to feature photos of all known Epicureans) and Wikipedia.
Anyone know of a good source for this? My first googling does not seem to turn up the answer.
