Oebalus

In Greek mythology, Oebalus, also spelled Oibalus or Oibalius, (Ancient Greek: Οἴβαλος,  Oíbalos) was a king of Sparta.

Family
Oibalus was the son of either Cynortas or Argalus. He was the second husband of Princess Gorgophone and thus son-in-law of the hero Perseus. With her or by the Naiad Bateia, Oibalos fathered Tyndareus,  Icarius and Hippocoon, as well as a daughter, Arene, who married her half-brother Aphareus. The nymph Pirene and Hyacinth were also called the daughter and son of Oebalius respectively. His grandchildren, the Dioscuri, were usually referred as Oibalids or Oebalidae.

Oebalus was often confused with Gorgophone's first husband, Perieres, son of Aeolus. They were separate people, usually unrelated though Oebalus was sometimes said to be Perieres’ son.
