Well, there's Theocritus' "Battle of the Bards", if you consider this site to be kosher, LV-wise.

There's also one by Euripides (full name "Euripides Eumendides") called "The Cyclops".

There's a rather whimsical, two-part, one-act play called "Yesterday" there that I wouldn't mind doing, if there is "A Certain Lady of Quality" who wants to play opposite "A British Officer, late of the Indian Army".
