I don't get this puritanical thing about not depicting deities with their assets on display. Pagans have never had a problem with it...
The Cerne Abbas Giant - a depiction of a Pagan god with a big willy. Hurrah for fertility.
Bes - an Egyptian ithyphallic god.
A statue of a Greek god, probably Pan (is that pose physically possible?)
Eye-watering depiction of Mercury from Pompeii
An ithyphallic image of Shiva from Nepal
