According to a myth from Ovids Metamorphoses—alluding to the connection of Pieria with the Muses—Pierus, king of Macedon, had nine daughters he named after the nine Muses, believing that their skills were a great match to the Muses. He thus challenged the Muses to a match, resulting in his daughters, the Pierides, being turned into chattering jays (with κίσσα often erroneously translated as magpies) for their presumption.Pausanias records a tradition of two generations of Muses; the first are the daughters of Ouranos and Gaia, the second of Zeus and Mnemosyne. Another, rarer genealogy is that they are daughters of Harmonia (the daughter of Aphrodite and Ares), which contradicts the myth in which they were dancing at the wedding of Harmonia and Cadmus. Children
Calliope had two sons, Ialemus and Orpheus, with Apollo. In another version of the story, the father of Orpheus was Oeagrus, but Apollo adopted him and taught him the skill of lyre while Calliope trained him in singing. Linus was said to have been the son of Apollo and one of the Muses, either Calliope or Terpsichore or Urania. Rhesus was the son of Strymon and Calliope or Euterpe. The sirens were the children of Achelous and Melpomene or Terpsichore. Kleopheme was the daughter of Erato and Malos. Hyacinth was the son of Clio, according to an unpopular account. Hymenaeus was assigned as Apollos son by one of the muses, either Calliope, or Clio, or Terpsichore, or Urania. Corybantes were the children of Thalia and Apollo.
