Rhadamanthys was the son of Zeus and Europa, and a king of Crete. He was raised by his step-father, Asterion. His brothers were Minos and Sarpedon. He was exiled from Crete by Minos, who was jealous of Rhadamanthys' popularity. He fled to Boeotia, where he married Alkmene (the widow of Amphitryon and mother of Herakles). He had two sons, Gortys and Erythrus. He is said to have tutored Herakles. King Rhadamanthys became one of the three judges of the dead, along with Aeacus and Minos.
