Deucalin (; ) was the son of Prometheus; ancient sources name his mother as Clymene, Hesione, or Pronoia. He is closely connected with the Flood myth, according to which, the anger of Zeus was ignited by the hubris of the Pelasgians. So Zeus decided to put an end to the Bronze Age. According to this story, Lycaon, the king of Arcadia, had sacrificed a boy to Zeus, who was appalled by this savage offering. Zeus unleashed a deluge, so that the rivers ran in torrents and the sea flooded the coastal plain, engulfed the foothills with spray, and washed everything clean. Deucalion, with the aid of his father Prometheus, was saved from this deluge by building a chest. Like the Biblical Noah and the Mesopotamian counterpart Utnapishtim, he uses his device to survive the deluge with his wife, Pyrrha.
