The Ancestor of Mortal Craft
Iapetus was one of the twelve Titans born to Uranus and Gaia, and the Greeks remembered him above all through his famous sons. As the father of Prometheus and Epimetheus, he was reckoned an ancestor of humankind itself — the Titan line from which mortal cunning, craft, and the very span of human life were thought to descend.
His name is of uncertain, likely pre-Greek origin, though it echoes the biblical Japheth and may share a distant root. Through the Oceanid Clymene he fathered four sons: Atlas, who holds up the sky; Menoetius, struck down by Zeus; clever Prometheus, who stole fire for mortals; and slow-witted Epimetheus, who accepted Pandora.
Iapetus sided with his brother Cronus in the war against the Olympians. Defeated in the Titanomachy, he was cast down into Tartarus, while his children carried his legacy into the age of Zeus — for good and for ill.
Prometheus, the most famous of Iapetus's sons, stole fire from Olympus and gave it to humanity in defiance of Zeus, who punished him by chaining him to a rock where an eagle devoured his regenerating liver each day — a torment ended only when Heracles freed him. Epimetheus, whose name means "afterthought," ignored his brother's warnings and accepted Pandora as a wife; the jar she opened released hardship and suffering into the world, according to Hesiod's Works and Days.
Because so much of humanity's fate — fire, craft, punishment, and endurance — traces back through his sons, later poets treated Iapetus almost as a distant ancestor of the human race, even though he himself appears in almost no myths of his own.

Why is Iapetus linked to mortality?
As the father of Prometheus and Epimetheus — the Titans tied to the creation and fate of humankind — Iapetus was associated with the mortal condition, craft, and the limited human lifespan.
Why was Atlas condemned to hold up the sky?
After the Titans' defeat in the Titanomachy, Zeus assigned Atlas the eternal punishment of bearing the heavens on his shoulders, a fate distinct from the imprisonment in Tartarus given to Iapetus and most of the other male Titans.
