[2] Acastus was the son of Pelias, then king of Iolcus,[3] and Anaxibia (Philomache in some traditions).
After the return of the Argonauts, Acastus's sisters were manipulated by Medea to cut their father Pelias in pieces and boil them.
[8] Acastus's wife (variously named in mythology; often Astydamia, but sometimes Hippolyte, daughter of Cretheus)[2] fell in love with Peleus but he scorned her.
[9] Acastus took Peleus on a hunting trip and hid his sword while he slept, then abandoned him on Mt.
With Jason and the Dioscuri, Peleus sacked Iolcus, dismembered Astydamia (and, in some accounts, Acastus himself), and marched his army between the pieces.
