The Titans of Greek Mythology

Definition: The Titans of the first generation are the aunts, uncles, and parents of the Olympian gods and goddesses. Thus, the Titans of Greek mythology are the twelve children of Gaia and Uranus:

• Cronus (aka Saturn)
• Rhea (Cronus and Rhea were the parents of the Olympian gods and goddesses)
• Iapetus (father of Prometheus, Atlas, and Epimetheus)
• Oceanus (father of nymphs)
• Hyperion (father of sun-god, moon, dawn)
• Themis (Zeus' second consort, mother of the Hours, Fates)
• Thea (Hyperion's mate)
• Mnemosyne (mated with Zeus to produce the Muses)
• Phoebe (Coeus' mate)
• Coeus (father of Leto & Asteria)
• Tethys (Ocean's mate)
• Crius (father of Pallas, Astraeus, and Perses)

The Titans Cronus and Rhea are the parents of Zeus and the other Olympian gods and goddesses.
Besides the Olympian gods and goddesses, the Titans produced other offspring, mating with either other Titans or other creatures. These offspring are also called Titans. The major second generation Titans are:

• Asteria
• Astraea (Dike)
• Astraeus
• Atlas
• Eos (Dawn)
• Eosphorus (or Hesperus)
• Epimetheus
• Helius
• Leto
• Menoetius
• Pallas
• Perses
• Prometheus
• Selene
