What Titan condemn by Zeus to support the heavens?

The Titan condemned by Zeus to support the heavens is Atlas. After the Titanomachy, the war between the Titans and the Olympian gods, Zeus punished Atlas for his role in opposing the gods by forcing him to hold up the sky, often depicted as carrying the celestial sphere on his shoulders. This punishment symbolizes the weight of responsibility and the burden of rebellion against the Olympian order.
