Oeagrus
In Greek mythology, Oeagrus (Ancient Greek: Οἴαγρος; Greek: Οίαγρος), son of Pierus or Tharops, was a king of Thrace. He and the muse Calliope were the parents of Orpheus and Linus. He was also sometimes called the father of Marsyas. There are various versions as to where Oeagrus's domain was actually situated. In one version, he ruled over the Edonian kingdom in the region of Mygdonia. He is also connected with Pieria, further west, or to the vicinity of the River Hebrus to the east; the latter was said to be called 'Oeagria', in his honor.
