Oeax (mythology)

In Greek and Roman mythology, Oeax or Oiax (Ancient Greek: Οἴακα or Οἴαξ means "handle of rudder, tiller") was a Euboean prince as the son of King Nauplius.

Family
Oeax's mother has been variously named as Clymene, Hesione or Philyra. He was also the brother of Nausimedon and Palamedes, a Greek warrior at the Trojan War.

Mythology
Because Oeax was angry at the Greeks for killing Palamedes at Troy, he falsely told Clytemnestra about Agamemnon bringing back Cassandra, a Trojan concubine, which led to Clytemnestra plotting to kill Agamemnon. Later, Oeax tried to banish Orestes after the latter murdered his mother Clytemnestra. Ultimately, Oeax and his brother Nausimedon were killed by Pylades after helping Aegisthus in his fight with Orestes.
