Always ithyphallic, bestial in appearance and behavior, Satyrs personified unlicensed sexual desire. Creatures with the body of a man and the ears and tail of a donkey, they were regarded as misshapen and monstrous, the very opposite of what was considered beautiful in a man, and the absurdity of their outrageous antics a source of humor.
They often are depicted as the importunate suitors of the Maenads. In the vase painting above, a Maenad wards off such unwelcome (and invariably unsuccessful) advances with her thyrsus.
