Arcadian nymph-companion of Artemis; raped by Zeus disguised as Artemis; transformed into a bear; nearly killed by her own son Arcas (already not recognizing her); translated into the heavens as Ursa Major. The eponym of the bear-constellation visible in the northern sky year-round — the catasterism is the etiological account for why the Bear never sets, transmitted from Hesiodic and pseudo-Eratosthenic astronomy.
