OceanusIn Greek mythology, Oceanus (oʊˈsiːənəs ; ɔːke.anós, also Ὠγενός ɔːɡenós, Ὤγενος ɔ̌ːɡenos, or Ὠγήν ɔːɡɛ̌ːn) was a Titan son of Uranus and Gaia, the husband of his sister the Titan Tethys, and the father of the river gods and the Oceanids, as well as being the great river which encircled the entire world. According to M. L. West, the etymology of Oceanus is "obscure" and "cannot be explained from Greek". The use by Pherecydes of Syros of the form (Ὠγενός) for the name lends support for the name being a loanword.
MnemosyneIn Greek mythology and ancient Greek religion, Mnemosyne (nɪˈmɒzɪniː,_nɪˈmɒsɪniː; Μνημοσύνη, mnɛːmosýːnɛː) is the goddess of memory and the mother of the nine Muses by her nephew Zeus. In the Greek tradition, Mnemosyne is one of the Titans, the twelve divine children of the earth-goddess Gaia and the sky-god Uranus. The term Mnemosyne is derived from the same source as the word mnemonic, that being the Greek word mnēmē, which means "remembrance, memory". A Titaness, Mnemosyne is the daughter of Uranus and Gaia.
ThemisIn Greek mythology and religion, Themis (ˈθiːmᵻs; Themis) is the goddess and personification of justice, divine order, law, and custom. She is one of the twelve Titan children of Gaia and Uranus, and the second wife of Zeus. She is associated with oracles and prophecies, including the Oracle of Delphi. Her symbol is the Scales of Justice. Themis means "divine law" rather than human ordinance, literally "that which is put in place", from the Greek verb títhēmi (τίθημι), meaning "to put.
MedusaIn Greek mythology, Medusa (mᵻˈdjuːzə,_-sə; Médousa), also called Gorgo, was one of the three Gorgons. Medusa is generally described as a human female with living venomous snakes in place of hair; those who gazed into her eyes would turn to stone. Most sources describe her as the daughter of Phorcys and Ceto, although the author Hyginus makes her the daughter of Gorgon and Ceto. Medusa was beheaded by the Greek hero Perseus, who then used her head, which retained its ability to turn onlookers to stone, as a weapon until he gave it to the goddess Athena to place on her shield.
IapetusIn Greek mythology, Iapetus (aɪˈæpɪtəs; ; Iapetós), also Japetus, is a Titan, the son of Uranus and Gaia and father of Atlas, Prometheus, Epimetheus, and Menoetius. He was also called the father of Buphagus and Anchiale in other sources. Iapetus was linked to Japheth (יֶפֶת) one of the sons of Noah and a progenitor of mankind in biblical accounts. The practice by early historians and biblical scholars of identifying various historical nations and ethnic groups as descendants of Japheth, together with the similarity of their names, led to a fusion of their identities, from the early modern period to the present.
HadesHades (ˈheɪdiːz; Háidēs, ˈhaiː.dεːs or ˈha.dεːs), in the ancient Greek religion and mythology, is the god of the dead and the king of the underworld, with which his name became synonymous. Hades was the eldest son of Cronus and Rhea, although this also made him the last son to be regurgitated by his father. He and his brothers, Zeus and Poseidon, defeated their father's generation of gods, the Titans, and claimed rulership over the cosmos.
