ARCAS
Arcas
In Greek mythology, Arcas was the son of Zeus and Callisto. Callisto was a nymph in the retinue of the goddess Artemis. Zeus, being a flirtatious god, wanted Callisto for a lover. As she would not be with anyone but Artemis, Zeus cunningly disguised himself as Artemis and seduced Callisto. The child resulting from their union was called Arcas.The above text is a snippet from Wikipedia: Arcas
