Achiroe

Achiroë (/əˈkɪroʊi/; Ancient Greek: Ἀχιρόη [akʰiróɛː]), Anchirrhoë (Ἀγχιρρόη), or Anchinoë (Ἀγχινόη), which is perhaps a mistake for Anchiroë, was in Greek mythology an Egyptian naiad, as daughter of the river-god Nilus. She was the wife of King Belus of Egypt, by whom she became the mother of Aegyptus and Danaus, and, according to some accounts, Cepheus, and Phineus.

Otherwise, the possible mother of these children and spouse of Belus was called Side, eponym of Sidon in Phoenicia.
