Diocorystes

Diocorystes appears in the Danaids cycle as one of the fifty sons of King Aegyptus. In the genealogical and narrative tradition he is paired in marriage with Hippodamia, one of the fifty daughters of Danaus. The core episode involving Diocorystes is the mass wedding in which the Danaids, following their father Danaus's command, killed their husbands on the wedding night; Diocorystes shares this fate along with his brothers except for Lynceus. Sources offer minor variants about his mother's identity (often an Arabian woman, with alternative attributions to Eurryroe or Isaie in some accounts).

No physical description of Diocorystes is preserved in the cited sources. He is attested only as a named participant in genealogical lists and the wedding-night narrative, without details of appearance, clothing, age, or iconography.

The sources do not attribute supernatural powers or special abilities to Diocorystes. His role is genealogical and narrative: a named son of Aegyptus and a victim in the Danaids' mass slaying of their husbands. He functions as part of a dynastic roster rather than as an active supernatural agent.
