According to various accounts of the creation of the world. Hesoid's version describes that in the beginning there was only Erebus, or darkness, Nyx, or night, and Chaos, which has been interpreted as the opening form from which the other ancient characters arose. Then Gaea, or mother earth, appeared, personified as the solid foundation of the world. Next was Tartarus, which is usually confused with the residence of Hades, but was depicted as the father of some of Gaia's children. After Chaos, Eros also appeared, the source of love/sexual attraction that united beings to produce more children. Gaea gave birth to Uranus, the sky, asexually and then gave birth to Pontus, the sea. From sexual union with Uranus, her son, she gave birth to the twelve titans (six males and six females), three Cyclopes and the Hecatonchires (one hundred hands). In her sexual union with Pontus she gave birth to the monsters who were Nerus (the wise old man of the sea), Ceto (the sea monster) and Chimera (the goat), among others. Cronus, the last born titan of Gaea, hated his father Uranus and ambushed him with Gaea, as he lay with her at night. Cronus grabbed his father and castrated him with the stone sickle, throwing his severed genitals into the sea. From his dripping blood the Giants and Erinyes were born. From the combination of the sea with the foam that dripped from her genitals, Aphrodite, the force of sexual attraction, was formed. The magic of these creatures bred and formed through sexual and asexual union is a miracle as such strange beings are brought into the world from the primal darkness. A final example of magic and miracles that we studied was the description of how Cronus tried to avoid being overthrown by one of his sons. He swallowed them as they were... in the middle of the paper... wrapped completely in "glittering fat" (something inedible hidden inside a pleasant appearance). Zeus chose the latter, setting a precedent for future sacrifices; thereafter, humans would keep the meat for themselves and burn the bones wrapped in fat as an offering to the gods. This angered Zeus, who hid the fire from the humans as punishment. Prometheus in turn stole fire from a giant fennel stalk and returned it to humanity. Prometheus was put in eternal punishment by Zeus. His punishment involves being chained to a rock, where his liver is eaten daily by an eagle. Years later, Heracles kills the eagle and frees Prometheus from his chains. This myth shows that in the very strict Greek society people or heroes are willing to risk their lives or reputations for others. This myth is very important to show that not all Greek myths had unhappy endings.
