This looks like a useful, growing, resource.
THEOI means “gods” in Greek. According to the site, it’s purpose is:
. . . exploring Greek mythology and the gods in classical literature and art. The aim of the project is to provide a comprehensive, free reference guide to the gods (theoi), spirits (daimones), fabulous creatures (theres) and heroes of ancient Greek mythology and religion.

Looks interesting, but the link is bad … page not found.
Thanks – fixed it!
