Eurydice was the daughter of King Lacedaemon and Queen Sparta, the legendary founders of Sparta and thus sister to Amyclas.1
Later on, Eurydice married King Acrisius of Argos and became the mother of Danaë who begot the celebrated hero Perseus. Her other daughter was possibly Evarete, wife of Oenomaus, king of Pisa in Elis.2 In some accounts, the wife of Acrisius was called Aganippe.3
