She was the wife of Idas and became by him the mother of Cleopatra, or Alcyone, wife of Meleager. Their daughter was called Alcyone because Marpessa was once carried off by Apollo, and lamented over the separation from her beloved husband, as Alcyon had once wept about Ceyx.
Idas carried off Marpessa, the daughter of Evenus, for whose hand Apollo also was suing, and was assisted by Poseidon, who gave him a winged chariot. Evenus, who pursued him, could not overtake him, but Apollo found him in Messene, and took the maiden from him.
The two lovers fought for her possession, but Zeus separated them, and left the decision with Marpessa, who chose Idas, from feat lest Apollo should desert her if she grew old. (Apollodorus i) The two brothers, Idas and Lynceus, also took part in the Calydonian hunt and in the expedition of the Argonauts.
In the latter expedition Idas killed the boar which had destroyed Idmon in the kingdom of Lycus, but when he attempted to deprive Teuthras, king of Mysia, of his kingdom, he was conquered by Telephus and Parthenopaeus.
The most celebrated part of the story of the Apharetidae is their fight with the Dioscuri, with whom they had grown up from their childhood.
"So long as Meleager was in the field things went badly with
the Curetes, and for all their numbers they could not hold their
ground under the city walls; but in the course of time Meleager
was angered as even a wise man will sometimes be. He was incensed
with his mother Althaea, and therefore stayed at home with his
wedded wife fair Cleopatra, who was daughter of Marpessa daughter
of Euenus, and of Ides the man then living. He it was who took
his bow and faced King Apollo himself for fair Marpessa's sake;
her father and mother then named her Alcyone, because her mother
had mourned with the plaintive strains of the halcyon-bird when
Phoebus Apollo had carried her off. Meleager, then, stayed at
home with Cleopatra, nursing the anger which he felt by reason of
his mother's curses. His mother, grieving for the death of her
brother, prayed the gods, and beat the earth with her hands,
calling upon Hades and on awful Proserpine; she went down upon
her knees and her bosom was wet with tears as she prayed that
they would kill her son--and Erinys that walks in darkness and
knows no ruth heard her from Erebus.
