What is "perimele"

In Greek mythology, Perimele or Perimela is the name of three mythical personages:

• Daughter of Hippodamas, who was loved by Achelous and lay with him secretly. When her father discovered that, he pushed her off a cliff into the sea. Achelous kept her floating on the waves for a while, imploring Poseidon to help her. Poseidon transformed her into an island which bore her name.
• Daughter of Admetus and Alcestis, mother of Magnes by Argus (son of Phrixus and Chalciope).
• Daughter of Amythaon. She and Antion, son of Periphas, were possible parents of Ixion.
