<span>The passage has a lot of inaccuracies. Zeus was never known as the most powerful god, he was simply king of the gods because he started the war against the Titans called the Titanomachy. Initially the Primordial gods were in power, until Gaia (first deity to ever be born) went to her children and asked them who would help her get rid of their father because she was mad he trapped their children, the Hecatonchires, in Tartarus. Only Cronus volunteered. He castrated his dad, Uranus, and then took over as king of the gods. When his wife (and sister) Rhea was pregnant with the first child, Hestia, he received a prophecy saying a son would overthrow him like he did his father. He therefore swallowed every child that Rhea bore him (including the female goddesses in case they had a son that could be the one to overthrow him). Rhea, when pregnant with Zeus, went to her mother and asked for his protection. She hid him in a cave on Crete where he was raised by a goat named Amalthea. When he was an adult, he returned to his father and used a mixture to have him throw up his siblings: Hestia, Demeter, Hera, Hades & Poseidon, all full-grown by this point. They took up home on Mt. Olympus and waged the 10-year long Titanomachy. Not all of the Titans stood by Cronus. Tethys, for example, helped Zeus. After 10-years of fighting, Zeus' uncles, the Cyclopses, made him his legendary thunderbolt which he used to free his other uncles, the Hecatonchires, from the depths of Tartarus. Using their 100 hands each (there were 3 of them), the Hecatonchires launched massive boulders at the Titans and sent them down into the depths of Tartarus, where they remained for a long time until Zeus released them. But at that point he had long been king of the gods and they settled in the background of Greek Mythology and were never really heard from again. </span>
