The Legend of the Shepherd Constellation (Boötes)

Boötes is traditionally depicted as a shepherd holding two hounds on a leash in one hand and a stick in the other. Seen in the sky, it is a constellation that follows the pole of Ursa Major. In legend, the constellation Boötes represents a plowman driving oxen in the constellation Ursa Major, followed by his two dogs Asterion and Chara (the constellation Canes Venatici is represented by hounds). Plowman’s oxen are tied to the polar axis, and their movements keep the sky in constant rotation.

Boötes represents Arcas, son of Zeus, and Callisto, daughter of Arcadian king Lycaon. Arcas was raised by his grandfather, the king, who decided to test Zeus by serving food to his own son. Zeus knows Lycaon’s intentions and turns the cruel king into a wolf. He strikes down all his sons and brings Arcas back to life. 

When Zeus’ wife, Hera, hears of her husband’s infidelity, she turns Callisto into a bear. Years later, Callisto wanders through the woods until she meets her now grown son. Arcas does not recognize his mother and starts chasing her. Callisto hides in a temple where he cannot harm a holy place without risking conviction for defiling it. To avoid a tragedy, Zeus sends them both into the sky. Here, Callisto takes on the role of Big Dipper and Arcas takes on the role of Boötes.
