Aegyptus was the twin brother of king Danaos of Argos. He became the king
of Egypt and Arabia.
From his father's side descended from Poseidon, while from his mother's side
from the River Nile.
King Vilos, who reigned in the African countries gave Arabia to Aegyptus and
Libya to Danaos. Aegyptus conquer the country of Melampus "those who have
black feet", and called her after his name Egypt.
Aegyptus had fifty sons by different women while his brother Danaos had
fifty daughters, the Danaides. The two brothers had a quarrel and eventually
Danaos fled in Argolis. The sons of Aegyptus went to Argolis to meet the
king and asked his daughters in marriage.
Danaos accepted their proposal, but the wedding night he put his daughters
to kill all the suitors. The only son of Aegyptus that was spared was
Lygkefs, because one of the Danaides, Ypermistra, fell in love with him and
she smuggled him out..
