Calisto, a nymph in the train of Diana, is seduced by Jupiter, under the form of that goddess, and is delivered of a son, named Arcas Juno transforms Calisto into the shape of a bear; but Jupiter removes both mother and child to the celestial mansions, where they are converted into a constellation called the Bear.
The day was settled in its course, and Jove Walk’d the wide circuit of the heavens above. To search if any cracks or flaws were made; But all was safe: the earth he then survey’d, And cast an eye on ev’ry different coast, And ev’ry land, but on Arcadia most. Her fields he clothed, and cheer’d her blasted face With running fountains and with springing grass. No tracks of heaven’s destructive fire remain, The fields and woods revive, and nature smiles again.
