PENEUS

also called Peneius, a Thessalian river god, and a son of Oceanus and Tethys. (Theogony of Hesiod 343; Metamorphoses by Ovid i.) By the Naiad Creusa he became the father of Hypseus, Stilbe, and Daphne. Cyrene also is called by some his wife, and by others his daughter, and hence Peneius is called the genitor of Aristaeus. (Hygin. Fab. 161)

Eros, the Greek God of Love, shot Apollo, the Greek God of the sun, with one of his arrows, causing him to fall in love with the dryad Daphne, daughter of Ladon. 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, and he changed her into a laurel tree, which later became sacred to Apollo. (Metamorphoses by Ovid)
