Belus

Poseidon united with Libya, daughter of Epaphus and Memphis. The land of Libya took its name from her. She bore twin sons, Belus and Agenor. Belus was also called Belos.

Belus remained in Egypt and became king there. Agenor left Egypt for Phoenicia, where he became king and founded a great line. In another telling, Agenor settled in the land of Canaan. He married Telephassa, also called Argiope. Their children included Cadmus, Phoenix, Cilix, Thasus, Phineus, and Europa. In one telling, Europa was the daughter of Phoenix instead.

Belus married Anchinoe, daughter of the Nile. She bore him the twin sons Aegyptus and Danaus. In one telling, Cepheus was a third son. In another, Cepheus and Phineus were also born to Belus and Anchinoe. Belus gave Danaus rule over Libya and Aegyptus rule over Arabia. Aegyptus conquered the land of the Melampodes and named it Egypt after himself. He later had fifty sons by different women. Danaus had fifty daughters, called the Danaids. After Belus died, the twins quarrelled over their inheritance. Aegyptus proposed marriages between his fifty sons and the fifty Danaids. Danaus suspected a plot and refused.
