Apollo carried off from Mount Pelion the nymph Cyrene, daughter or granddaughter of the river-god Peneus, and conveyed her to Libya, where she gave birth to Aristaeus.
Alpheus was recognized in cult and myth as the chief or typical river-god in the Peloponnesus, as was Achelous in northern Greece.
Such a spot he found at the mouth of the river Achelous, where an island had recently been formed by the alluvial deposit; here he settled and, forgetting his wife Arsinoe, married Callirrhoe, the daughter of the river-god.
The name appears in cult and in mythology as that of the typical river-god; a familiar legend is that of his.
