Achiroe

According to genealogical myth reported in Apollodorus (summary preserved in modern sources), Belus remained in Egypt, reigned there, and married Anchinoe (Achiroe), daughter of the river-god Nilus; by her he fathered twin sons Aegyptus and Danaus. Apollodorus also records, citing Euripides, that Belus was said in some accounts to have had Cepheus and Phineus as well. An alternative tradition recorded in the corpus substitutes Side (eponym of Sidon) as Belus's wife, indicating regional or textual variation in genealogical attributions.

Surviving sources classify Achiroe only as a naiad (freshwater nymph) associated with the Nile and give no physical or iconographic description. The tradition preserves her identity and relationships but offers no bodily details.

The cited accounts do not attribute active supernatural deeds, specific powers, cult, or myths of action to Achiroe; her role in the preserved tradition is genealogical—she marries Belus and bears children who serve as eponymous or foundational figures. As a named naiad she is implicitly a personification of riverine fertility in Greek mythic taxonomy, but no explicit abilities or behaviors are described in the provided sources.
