The Sons of Iapetus and Their Fates
2 source witnesses · 2 source-scoped variants · reviewed 2026-08-30
Hesiod and Pseudo-Apollodorus preserve competing maternal genealogies for Iapetus’s four sons and attach different punishments and burdens to each brother.
Canonical narrative
Clymene enters Hesiod’s genealogy beside Iapetus and bears Atlas, Menoetius, Prometheus, and Epimetheus. The poem does not hand the brothers a common office. It immediately separates them through four consequences, while Iapetus remains the father at the root of the branch.
Atlas stands at the earth’s limit before the Hesperides, holding wide heaven with unwearying head and arms under a hard necessity assigned by Zeus. Menoetius, swollen with presumption and violent strength, is struck by the thunderbolt and sent down to Erebus. One son remains beneath a lasting burden; another vanishes into ruin.
Prometheus receives the longest suffering. Zeus binds him, drives a shaft through his body, and sends a long-winged eagle to consume his liver. The organ grows again, renewing the torment until Heracles kills the bird with Zeus’s consent. Epimetheus meets a different consequence. Hesiod calls him a grief to bread-eating humanity because he accepts the woman Zeus has fashioned.
Pseudo-Apollodorus preserves the same four sons but names Asia as their mother. His compact account says Atlas bears the sky on his shoulders and makes Menoetius’s fall part of the battle with the Titans, where Zeus strikes him and casts him into Tartarus. The passage names Prometheus and Epimetheus but does not narrate the eagle, Heracles, or the fashioned woman.
The maternal names and punishments remain side by side rather than melting into one version. Iapetus is common to both genealogies, but the sons’ burdens, errors, and endurance do not become powers possessed by their father.
