PROETUS

in Greek mythology, a king of Argos, grandson of Danaus. He quarreled with his brother Acrisius and divided the kingdom with him, Proetus taking Tiryns, which he fortified. Proetus' daughters were driven mad either because they insulted the goddess Hera or because they would not accept the new rites of Dionysus. They imagined themselves cows, until the seer Melampus cured them on condition that he be given a third of the kingdom and his brother, Bias, another third. See also Bellerophon.
