Cassini correctly surmised that Iapetus has a bright hemisphere and a dark hemisphere, and that it is tidally locked, always keeping the same face towards Saturn. This means that the bright hemisphere is visible from Earth when Iapetus is on the western side of Saturn, and that the dark hemisphere is visible when Iapetus is on the eastern side.
Iapetus ("the Piercer") is the one Titan mentioned by Homer in the Iliad as being in Tartarus with Cronus. He is a brother of Cronus, who ruled the world during the Golden Age. Iapetus' wife is usually described as a daughter of Oceanus and Tethys named either Clymene (according to Hesiod and Hyginus) or Asia (according to Pseudo-Apollodorus).
The Iapetus Ocean (pronounced / aɪ ˈ æ p ɪ t ə s /) was an ocean that existed in the late Neoproterozoic and early Paleozoic eras of the geologic timescale (between 600 and 400 million years ago). The Iapetus Ocean was situated in the southern hemisphere, between the paleocontinents of Laurentia, Baltica and Avalonia.
Iapetus is a large moon of Saturn.It was discovered by Giovanni Domenico Cassini in 1671.. Iapetus is unusual: one side is very bright and the other side is very dark. This is because one half of the moon is covered in ice and the other side is coated in black, dusty carbon deposits.

The Iapetus suture runs where the Iapetus Ocean was before. In Great Britain the suture runs pretty much along the border between England and Scotland. On the east it runs through Lindisfarne, on the west through the Solway Firth. On the Isle of Man it is the Niarbyl Fault, which is an exposed section of the suture.
Saturn's moon Iapetus has a long, 20-kilometer-high ridge running along most of its equator. It was discovered by the Cassini probe in 2004. The ridge's origin is unknown. There are bright areas on the sides of the equatorial ridge near Iapetus' bright trailing hemisphere, which were already visible in Voyager 2 images appearing like mountains and were nicknamed the "Voyager Mountai

Iapetus was the fifth son to be born to Gaia and Ouranos, the respective personifications of the earth and sky. The Titans were the eldest of the three races born to Gaia the Earth and Ouranos the Sky, before the Hekatonkheires (Cottus, Gyges, and Briares) and the Elder Cyclopes (Arges, Brontes, and Steropes). All were detested by their father, but he detested the younger children so much (mainly for their ugliness) that he imprisoned them in the terrifying abyss of Tartarus, which was itself...
Murder of Ouranos
While preparing to ambush his father Ouranos, Iapetus hid himself by posing as a tree (with his arms spread out). Together with his brothers Hyperion, Krios, and Koios, Iapetus held Ouranos down, after which Kronos used the Scythe to slice Ouranos into a thousand pieces and claim his supremacy over the universe. During the murder, Iapetus was kicked in the face by his thrashing father (something his brothers frequently teased him about afterwards). However, right before Kronos sliced him up,...
The Titan Lord of the West
After Kronos claimed his supremacy as the Titan King of Mount Orthys, and ushered in the "Golden Age", Iapetus was justly rewarded for his help with control over the West. Iapetus' usually very calm, "as calm as the sunset", in stark contrast to his passionate and ferocious brother Hyperion. However, Iapetus was capable of great displays of anger as well, and was later nicknamed "The Piercer" due to his great skills at fighting with a long spear. Iapetus would also frequently approach his wis...
Iapetus is indirectly mentioned by Annabeth Chase while she and Jason Grace were in the Hypnos' Cabin asking about losing memories and how to retrieve them. She says that Percy had told her that the River Lethe could wipe even a Titan'smemory. It can be said that she was referring to Iapetus.
Later, they were attacked by five empousai, one of them being Kelli. While they were in no state to fight, they tried to talk and trick them into leaving them. This worked partially as Kelli killed one empousa but still they were outnumbered. Just as two empousai were about to kill Percy, a shadow fell and Iapetus (believing he was Bob) dropped out of the sky and stomped Kelli flat. Bob used his broom to kill the other empousai. His broom could jut out a spear head from its end and could retu...
As Iapetus, he was somewhat cruel and arrogant, just like his brothers. However, according to his brother Hyperion, Iapetus was always "conflicted" about helping murder Ouranos, and even describes him as "the soft Titan of the West, soft as the sunset." This implies that while Iapetus was cruel, he was never quite as brutal as his other brothers, namely Kronos and Hyperion. This is confirmed to be true in Percy Jackson's Greek Gods, where Iapetus is shown to be calm and patient (in stark cont...
After losing his memories, Iapetus is told by Percy that he is his friend, Bob. As Bob, Iapetus became more friendly, gentle, amiable and somewhat childlike. In the House of Hades, he's shown to be bored of his new duties, as Hades (who despised his Titanic uncle) treats him like a slave, and orders him to clean all the messes in the Underworld. Iapetus is shown to have good hearing as he was able to hear Percy call his name all the way from Tartarus (though he might share this skill with oth...
After escaping Tartarus, Iapetus wore a tattered orange prison jumpsuit, has wild Einstein silver hair that sticks up in every direction, a scraggly long beard, pure silver eyes, and is very thin and haggard and is said to be 10 feet tall. However, after he had his memory erased and started working for Hades, he wears a blue janitor's uniform and a name tag that reads "Bob" and carries around a massive push broom. As mentioned in The House of Hades, he also bears great resemblance to his brother Hyperion, apart from Iapetus's signature color being silver instead of Hyperion's gold. While in Tartarus, Iapetus's silver hair glows in the dark.Prowess in Battle: As an Elder Titan, Iapetus was an excellent warrior, though he was defeated in the First Titanomachy.

After the Titan Iapetus lost his memory, Nico would visit him at his father's palace. He would convince Bob that Percy was a good person, which would eventually lead to the Titan helping Percy and Annabeth reach the Doors of Death from inside Tartarus.
He is the only Titan that is on the good side with Percy. In The Demigod Files, while he is fighting Percy, Percy tricks him into splashing into the River Lethe, wiping his memory clean. He emerges believing he is a man named Bob and his friend is Percy though he finds out that he is actually not later in Tartarus. However, he is presumed dead after fighting the embodiment of Tartarus and ensuring Percy and Annabeth reach the mortal world safely in The House of Hades.Iapetus, the third largest moon of Saturn, is named after him.Iapetus being the Titan of mortality is fitting as his sons Prometheus and Epimetheus were responsible for creating mortal creatures (humans and animals respectively).According to Hyperion, Iapetus was the least cruel of the Elder Titans, though if this statement included Oceanus, who was neutral against their father and the first Titanomachy, is unclear.
- How Iapetus Got Its Name
Giovanni Cassini discovered Iapetus on Oct. 25, 1671. However, to astronomers Iapetus appeared only as a dot whose brightness varied from brighter to fainter over the course of an orbit around Saturn. The Voyager I and Voyager II encounters in 1980 and 1981 validated Cassini's original observations and explanation with images showing the different reflectivity of Iapetus' hemispheres.
Iapetus has been called the yin and yang of the Saturn moons because its leading hemisphere has a reflectivity (or albedo) as dark as coal (albedo 0.03-0.05 with a slight reddish tinge) and its trailing hemisphere is much brighter at 0.5-0.6. Saturn's third largest moon, Iapetus has a mean radius of 457 miles (736 kilometers) and a density only 1.2 times that of liquid water. It has been suggested that Iapetus (like Rhea) is three quarters ice and one quarter rock. Iapetus orbits at 2,213,000 miles (3,561,000 kilometers) from Saturn. The great distance from Saturn's tidal forces and from most of the other moons and ring particles has probably allowed the Iapetus surface to be largely unaffected by any melting episodes that could have caused some smoothing or "resurfacing" as on some of the moons closer to Saturn. However, despite the great distance, Saturn has tidally locked Iapetus. The moon always presents the same face toward Saturn. With its distant, inclined orbit, Iapetus is t...
John Herschel suggested that the moons of Saturn be associated with the mythical brothers and sisters of Kronus. (Kronus is the equivalent of the Roman god Saturn in Greek mythology.) The name Iapetus comes from the Greek god (or Titan) Iapetus, who is a son of Uranus and Gaia, a brother to Kronus and the father of Atlas and Prometheus. As the father of Prometheus, the ancient Greeks regarded Iapetus as the father of the human race. Cassini referred to Iapetus as one of the four Sidera Lodoicea (Stars of Louis) after King Louis XIV (the other three were Tethys, Dione and Rhea). Other astronomers called Iapetus by its number in the order of moons discovered at the time. Iapetus started as Saturn V, and it became Saturn VIII after additional moons were discovered. Geological features on Iapetus generally get their names from the French epic poem "The Song of Roland."
