The Great Bear in myth and astrology
The Great Bear's story is about transformation and a place that never changes: a woman turned into a bear and set in the one part of the sky that, from Greece, never set.
What the story carries
Transformation, punishment and rescue: in every version Callisto loses her human form and gains a place in the sky.
In the account Hyginus credits to Hesiod, Diana turns Callisto into a bear (opens in a new tab), and Jupiter later places her and her son in the sky; other writers blame Juno, or name the girl Megisto. The common thread is a punishment followed by a rescue into permanence.
The sky supplies the moral: the bear does not set (opens in a new tab), and one story says Tethys refuses to let her into the sea. Historical beliefs sets out who told which version.

What Ptolemy assigned
Ptolemy compared the Great Bear's bright stars to Mars, and the Little Bear's to Saturn and Venus.
Among the stars north of the zodiac, Ptolemy (opens in a new tab) likens the bright stars in Ursa Minor to Saturn and, to a lesser degree, Venus, and those in Ursa Major to Mars.
He adds the cluster beneath the Bear's tail, Coma Berenices (opens in a new tab), likening it to the Moon and Venus, and Arcturus, the bright tawny star of Boötes the bear-watcher, to Jupiter and Mars.
Keep in mind These are one ancient astrologer's analogies, reported as history, not forecasts and not properties of the stars.

In the sky
The bear is Ursa Major; its brightest seven stars are the Big Dipper.
Ursa Major is the third-largest constellation (opens in a new tab); the seven stars of the Big Dipper are its rump and tail.
The bear's refusal to set is real for northern observers: stars near the pole (opens in a new tab) trace small circles and stay up all night. It is a fact of where you stand, not a property of the bear.
