The Big Dipper refers to Greek mythology: Zeus, the king of the gods, lusted after a young woman named Callisto, a nymph of Artemis. Hera, Zeus' jealous wife, transformed the beautiful Callisto into a bear. Callisto, while in bear form, later encountered her son Arcas. Arcas almost shot the bear, but to avert the tragedy, Zeus hurled them both into the sky, forming Ursa Major, the constellation of which the Big Dipper is part. Callisto is then seen as the mother of the Arcadians, through her son Arcas. The people of Granida chose the Big Dipper because of its connection to the utopian concept of Arcadia, a pastoral setting in harmony with nature. The most notably knew the concept through Sidney's The Countess of Pembroke's Arcadia.
