Who was Iapetus?
Iapetus was a Titan, one of the sons of Gaia and Uranus. He is probably best remembered as the father of Atlas and Prometheus.
What was Iapetus the god of?
As one of the Titans cast down from the heavens, Iapetus was not widely worshipped in the ancient world and does not seem to have had any definite domain for his divinity. Some modern scholars, however, view him as a symbol of mortality.1
Is anything named after Iapetus?
Iapetus is the name of one of the largest moons of Saturn, first identified in the 1600s but not definitively named until 1847 by John Herschel.
Iapetus, son of Gaia and Uranus, was one of the original twelve Titans of Greek mythology. With his wife Clymene, he fathered several significant mythological figures, including Atlas, Prometheus, Epimetheus and Menoetius. After helping to overthrow his father Uranus, Iapetus fought against the Olympians in the Titanomachy. When the Titans were ultimately defeated, he was among those doomed to suffer for all eternity in the dark pit of Tartarus.
The name Iapetus may be derived from the Greek word iaptein, meaning “to hurl” or “to wound.” This would make Iapetus “the one hurled down,” perhaps referring to his expulsion to Tartarus by Zeus and the Olympians.
Other scholars have argued that Iapetus’ name is pre-Greek in origin and can be traced to the biblical Japheth, the third son of Noah. Indeed, both figures were believed to be progenitors of humanity: Japheth was often regarded as the ancestor of the inhabitants of Europe, while Iapetus was the father of Prometheus, sometimes considered the creator of the human race.

Like most of the Titans, Iapetus was rarely individualized in ancient literature. Consequently, his precise attributes remain a mystery. However, Iapetus may have been associated with the attributes of his sons, such as the cleverness of Prometheus or the strength of Atlas, who held the heavens upon his shoulders.
Iapetus was one of the twelve Titans who emerged from the primordial union of Gaia, the personification of the earth, and Uranus, the embodiment of the heavens. His brothers and sisters included not only the other Titans—Coeus, Crius, Hyperion, Thea, Rhea, Themis, Mnemosyne, Phoebe, Oceanus, Tethys, and Cronus—but also the monstrous Cyclopes and Hecatoncheires.
According to the standard account (as told by Hesiod), Iapetus took Clymene, the daughter of Oceanus and Tethys, as his wife. Other sources, however, assigned him different wives, including Asia or Themis.
Iapetus had four children: Prometheus, who gave fire to humans (and, in some sources, was also their creator); Atlas, who held the celestial sphere on his back; Epimetheus, a dim-witted ambassador to the human race; and Menoetius, who was slain by Zeus for his hubris when he fought against the Olympians. In some traditions, Iapetus was also the father of Anchiale and Buphagus. The Roman mythographer Hyginus listed one additional son, Dryas, a hero who participated in the Calydonian Boar Hunt.
Hyginus, most likely confusing the Titans with the Giants, broke from tradition by calling Iapetus a Giant, the son of Gaia and Tartarus.
According to Hesiod’s Theogony, Iapetus was the son of Gaia and Uranus. He took Clymene (an Oceanid) as his lover, and they had many children:
Now Iapetus took to wife the neat-ankled ma[i]d Clymene, daughter of Ocean, and went up with her into one bed. And she bare him a stout-hearted son, Atlas: also she bare very glorious Menoetius and clever Prometheus, full of various wiles, and scatter-brained Epimetheus who from the first was a mischief to men who eat bread.
Iapetus was loyal to his brother Cronus, the leader of the Titans; when Cronus rose up against their father Uranus, Iapetus helped hold Uranus down while Cronus severed his genitals with a scythe. Later, Iapetus fought alongside Cronus during the Titanomachy, the ten-year war between the Titans and Zeus’ Olympians. This war split Iapetus’ family down the middle: while two of his sons, Atlas and Menoetius, fought with him on the side of the Titans, the other two, Prometheus and Epimetheus, sided with the Olympians.
When Zeus finally emerged victorious, he punished the Titans severely, rounding them up and casting them into the hellish pit of Tartarus—Iapetus included. In some traditions, however, Iapetus was actually buried under the island of Inarime.
Iapetus and the other Titans were usually thought to have been imprisoned for all eternity. There was, however, another version in which Zeus was merciful and eventually released the Titans (all except Iapetus’ son Atlas, who was still forced to hold up the sky).
In Greek and Roman literature, Iapetus was most often named in connection with his more famous sons. Prometheus, for example, was sometimes referred to as the “son of Iapetus.” In Hesiod’s Works and Days, Zeus uses this epithet to address Prometheus following his theft of fire: “Son of Iapetus, surpassing all in cunning, you are glad that you have outwitted me and stolen fire—a great plague to you yourself and to men that shall be.”
Not much else is known about Iapetus; as such, it is difficult to determine what the title “son of Iapetus” may have meant to the ancient Greeks (beyond a simple expression of lineage).
Iapetus was almost never worshipped in cult, but there is one inscription suggesting that he received some sort of religious honors on the island of Imbros.
Iapetus appears as a villain—and later a hero—in Rick Riordan’s Heroes of Olympus book series. The transformation occurs after the ignoble Iapetus is cast into the River Lethe, which absorbs memories. With his evil forgotten, Iapetus emerges as a heroic figure named Bob who assists the Olympians in defeating the giants.
Iapetus also lent his name to Saturn’s third largest moon. Discovered in 1671 by Italian astronomer Giovanni Domenico Cassini, the moon was named in the mid-nineteenth century at the suggestion of John Herschel.
