Iapertos（ Ιά π ετος） He is the son of Uranus and Gaia, one of the giants, and the father of Atlas, Prometheus, Epimethes, and Menotius. The ancient Greeks regarded him as the ancestor of humanity.

Under the leadership of Cronus, Iaptos colluded with his brothers to deceive Uranus and complete the castration of their father.
In this myth, Iapetus and three brothers represent four pillars of the universe. Iapetus is undoubtedly the pillar of the west. Later, his son Atlas told us more accurately.
The "piercer" of the clergy Iapetus may also be the lifespan of mortals regarded as gods by Iapetus. In fact, his two sons Prometheus and Epimetheus both claim to be creators of humans and other deadly creatures. In the end, Zeus overthrew the Titans and sent them to the hell of Tartaros. In the description of the ancient Greek poet Hesiod, the Titans had the power to control the earth, ocean, and sky, where they established the order of the universe and were regarded as the bearers of the entire universe. According to Pindar and Aeschylus' "In his lost play Prometheus Unbound," the Titans were ultimately pardoned by Zeus.
The etymology of the name Iapetos is related to Japheth, the son of Noah, in Hebrew mythology. As an ancestor of a group of people, Yafu may have a similar ancient Indo European name etymology to Iapetos.

The wife of Iaptos, some say she is the goddess of fame Clymene, some say she is Asia, and some say she is Themes. In short, he and his wife gave birth to four second generation Titans: ATLAS, PROMETHEUS, EPIMETHEUS and MENOITIOS. Therefore, he can be regarded as the ancestor of humanity (in Greek mythology, humans were created by Prometheus).
