Legend has it that the god Uranus, or Coelo, first king of the Universe, personified the sky. For Hesiod, a Greek poet who probably lived in the 7th century BC, he was, at the same time, the son and husband of Geia, a goddess born immediately after the original Chaos and also known as Titea, Ops, Telos, Vesta and Cybele. In his book Theogony, which deals with the genealogy and affiliation of the gods, Hesiod says that from this union several gods and demigods were born, about forty-five, according to some authors.
Among them Oceano, Iapetus, Themis, Cronos, the Titans, the Cyclopes and the hecantoquiros, the "one hundred hands", three giants called Briareu, Coto and Giges, possessing one hundred arms and fifty heads, each, to which the Romans gave the name of Centimanos.
