Aegimius

For the ancient Greek physician sometimes called Aegimius, see Aegimus. Aegimius (Gr. ) was the Greek mythological ancestor of the Dorians, who is described as their king and lawgiver at the time when they were yet in­habiting the northern parts of Thessaly. He asked Heracles for help in a war against the Lapiths and, in gratitude, offered him one-third of his kingdom. The Lapiths were conquered, but Heracles did not take for himself the territory promised to him by Aegimius, and left it in trust to the king who was to preserve it for the sons of Heracles.

[Greek] The mythical ancestor of the Dorians. He battled with the Lapiths and asked Heracles for help, and with Heracles' help they were victorious. Aegimius tried to reward Heracles with a third of his land, but Heracles graciously declined the offer. Aegimius therefor adopted Heracles' son Hyllus as his own son to show his gratitude. Together with the other two sons of Aegimius, namely Pamphylus and Dymas, Hyllus lend his name to the three Dorian tribes: Pamphylii, Dymanes, and Hylles.
