Oceanus is the unending stream of water encircling the world. Together with his wife Tethys produced the rivers and the three thousand ocean nymphs.

Mnemosyne was the Titan of memory and the mother of Muses.

Iapetus was the father of Prometheus, Epimetheus, Menoetius, and Atlas by Clymene.

Rhea was the wife of Cronus. Cronus made it a practice to swallow their children. To avoid this, Rhea tricked Cronus into swallowing a rock, saving her son Zeus.

Metis was the Titaness of the forth day and the planet Mercury. She presided over all wisdom and knowledge. She was seduced by Zeus and became pregnant with Athena. Zeus became concerned over prophecies that her second child would replace Zeus. To avoid this Zeus ate her. It is said that she is the source for Zeus wisdom and that she still advises Zeus from his belly. It may seem odd for Metis to have been pregnant with Athena but, never mentioned as her mother. This is because the classic Greeks believed that children were generated solely from the fathers sperm. The women was thought to be nothing more than a vessel for the fetus to grow in. Since Metis was killed well before Athena's birth her role doesn't count.

Atlas was the son of Iapetus. Unlike his brothers Prometheus and Epimetheus, Atlas fought with the other Titans supporting Cronus against Zeus. Due to Cronus's advance age Atlas lead the Titan's in battle. As a result he was singled out by Zeus for a special punishment and made to hold up the world on his back.
