In Greek mythology, Deucalion was the son of Prometheus; ancient sources name his mother as Clymene, Hesione, or Pronoia. He is closely connected with a flood myth in Greek mythology.

In Greek mythology, Hellen is the eponymous progenitor of the Hellenes. He is the child of Deucalion and Pyrrha, and the father of three sons, Dorus, Xuthus, and Aeolus, by whom he is the ancestor of the Greek peoples.
