This aluminum casting is an 8:1 enlargement of an Ancient Athenian coin, commissioned by a private client.
Athena, the patron goddess of ancient Athens, was often depicted with an owl on her shoulder, the owl being a symbol of wisdom. Harryhausen enthusiasts like myself will also recognize that Bubo, the clockwork owl from the original Clash of the Titans, is based on this design. I suggest hanging this piece next to a framed photo of Harry Hamlin.
