Triopas

In Greek mythology, Triopas was one of the Heliadae, sons of Helios and Rhodus.

Triopas, along with his brothers, Macar, Actis and Candalus, were jealous of a fifth brother, Tenages's, skill at science. They killed him. Triopas escaped to Cos and then founded the city of Cnidus. He was the father of Erysichthon.
