Mythology of Boötes
In Greek mythology, Boötes was identified with several mythological figures. One was Aristaeus, a minor deity associated with agriculture. Another was Icarius, a friend of the wine god Dionysus. Icarius was famous for teaching humans how to make wine, but he was also killed by shepherds who had too much of his wine and thought he was trying to poison them. After his death, he was placed in the stars as Boötes.
In another myth, Boötes was identified with Arcas, the son of the god Zeus and the nymph Callisto. When Callisto was turned into a bear by Zeus’ jealous wife Hera, Arcas almost killed her. Zeus intervened and placed both Callisto and Arcas in the sky as Ursa Major and Ursa Minor, and Boötes was placed nearby as a protector.
