“ DANAUS, in Greek legend, son of Belus, king of Egypt, and twin-brother of Aegyptus. He was born at Chemmis (Panopolis) in Egypt, but having been driven out by his brother he fled with his fifty daughters to Argos, the home of his ancestress Io. Here he became king and taught the inhabitants of the country to dig wells. In the meantime the fifty sons of Aegyptus arrived in Argos, and Danaus was obliged to consent to their marriage with his daughters. ”
