Eros shot Apollo with one of his arrows, causing him to fall in love with Daphne. It was Eros's plan that Daphne would scorn Apollo because Eros was angry that Apollo had made fun of his archery skills. Eros also claimed to be irritated by Apollo's singing. Daphne prayed to the river god Peneus to help her. He changed her into a laurel tree, which later became sacred to Apollo.
