Aura, a wind nymph

A 19th Century French School painting tentatively identified as "Hylas and a Nymph" -the encounter of one male and one female suggests the mythological story of the nymph Salmacis seducing the youth Hermaphroditus

They are not immortal, like Greek gods or the titans from Greek mythology, but were said to live a long time.
