This man may just be my hero! Combining sexuality and the Ancient World - at least I'm not the only one out there who sees how wonderful the union is. Besides, his animation skills are divine.
Check out some of his work here.
My favorites are: Mythology (particularly like the "Education of Achilles"), Laoccon (story told in pictures), the Decline and Fall of the Roman Empire (just plain awesome!), and Ludi Romani!
These are depictions of gay sexual acts, just so you are warned ahead of time.
