Titans
Atlas
In Greek mythology, Atlas is a titan who holds a celestial vault around his neck as punishment for leading a rebellion against the gods. He was the son of the titan Íapetus and Clymene (daughter of the titan Okeanos). His brothers were Prometheus, Epimetheus and Menoitios.
Atlas had many children, namely Hesperides (mother - goddess Nyx), Hyades and Hyanta (mother - goddess Aithra), Pleiades (mother - Pléiona) and also had children, where it is not known who their mother was, among them is the nymph Kalypso.
When the Titans rebelled against the Olympian gods, it was Atlas who took the lead, although Kronos was still alive. In contrast, his brothers (Prometheus, Epimetheus and Menoitios) sided with the gods. When Zeus put down this rebellion, even with the help of the Cyclopes, he overthrew the Titans in Tartarus, with the exception of Atlas. He punished him by making him carry the vault of heaven as a warning to the others.
This curse he only got rid of once, and that was after the arrival of the hero Heracles, who came for the golden apples of the Hesperides. Atlas offered to bring him these apples if he would hold the vault of heaven for him. Heracles recognized the ambush, but agreed, because that way he would not have to fight the invincible dragon Ladon in the garden of the Hesperides. When Atlas fetched the apples, Heracles tricked him by saying that he wanted to pad his shoulder with grass and that Atlas would hold the vault for a while. As soon as Atlas took the vault, Heracles left with the apples.
Other sources claim that Heracles built two columns under the vault of heaven to hold it up, thus saving Atlas.
When Perseus was returning home after killing Medusa, he also passed Atlas on the way. Atlas, however, refused him a treat and, moreover, questioned Perseus' deeds. So Perseus pulled out Medusa's head and showed it to Atlas, who, upon seeing it, immediately turned into a mountain of stone, towering to the heavens. And so, even in death, he holds forever the vault of heaven.
