Day by day we watched the gradual metamorphosis of the tadpoles into frogs.
Many myths end in a metamorphosis.
As Apollo is chasing the nymph Daphne, she calls on her river-god father for help and he turns her into a laurel tree to save her. Out of anger and jealousy, the goddess Athena turns the marvelous weaver Arachne into a spider that will spin only beautiful webs. And the transformation of caterpillars into butterflies is the most famous of natural metamorphoses.
