The brothers of Prometheus are Atlas, Epimetheus, and Menoitios
Prometheus is the brother of Menoetius, Atlas, and Epimetheus. His father was Lapetus the Titan and his mother was Clymene, an elemental Oceanid.
Prometheus means, "One with foresight". The Olympian god Prometheus had the power of forethought/foresight.
The mythological Prometheus had a son named Deucalion. Deucalion was the Greek mythology equivalent of Noah. Zeus caused a great flood while he was angry at King Lycaon. Deucalion (son of Prometheus) created a Chest (same as Ark) to save himself and his wife during the great flood.
They keep Saturn's rings in order.
He isn't a god, Prometheus is a titan, after being freed, Prometheus told Heracles not to pick the apples, but to get Atlas to get them, by tricking him.
The brothers of Prometheus are Atlas, Epimetheus, and Menoitios
Atlas had several siblings, his parents were Iapetos and Clymene and their children included Epimetheus, Prometheus, Bouphagos, Menoitios and Anchiale.
Epimetheus and Atlas
Epimetheus and Atlas.
The siblings of Atlas were Prometheus and Epimetheus. They were all Titans in Greek mythology, with Atlas being known for carrying the weight of the heavens on his shoulders.
You're two qualifiers are mutually exclusive. Prometheus and Atlas were not human, they were Titans, and so their parents were Titans as well. They were not ancestors of humans any more than one could say that God is an ancestor of man. Prometheus CREATED man in Greek mythology. That hardly makes him an ancestor. Remember, Wikipedia is edited by everyone... and some people are idiots. For the record, though, Prometheus and Atlas were sons of Iapetos.
The father of Prometheus is Iapetus. He was also the father of Atlas.
Atlas and Epimetheus
Atlas, Prometheus, Epimetheus, and Menotius.
Atlas and Epimetheus
Fathering Atlas, Prometheus, and Epimetheus. Just so you know, Iapetus is more correctly identified as a Titan.
