Uranus is recognized as the second of all Gods to arrive. He was created by Gaia, the Goddess of the Earth, and was known as the God of the Sky and the Heavens, as well as the propagator and ruler of the Gods to follow. Uranus was also the partner to his Mother, Gaia, and the two had many offspring together. They raised the twelve Titans who were the predecessors to the Olympian Gods. He was the father of Cronus (aka Saturn), the youngest of the Titan males, He was also the grandfather of Zeus, who was commonly referred to as Jupiter by the Romans. Uranus also fathered the three Cyclopes, and the Hecatonchires after them.
Uranus may have been considered the first of the universal rulers and God to all the following Gods, but his reign as the first powerful God did not leave his legendary status in very high regard. When you consider the Gods that came to follow him, it seems he had little tolerance and was heavy handed in his rule. Chaos seemed to follow Uranus under his reign. After the Titans were born, Uranus must have expected that all his children to follow would be just as superb in physique and stature. This was not the case however, as his following offspring were the three one-eyed Cyclopes, whom he could not stand the sight of. He locked them away in the darkness so he did not have to look at their deformities ever again. His next offspring, the Hecatonchires were an even worse disaster for him. They were born with fifty heads and one hundred hands each. Following his pattern to remove anything ugly from his view, he locked them away with the Cyclopes, never wishing to see them again either.
What Uranus also did not see was how upset their loving mother, Gaia, had become over the treatment of her adored children. She had no choice but to remove him from Earth, so no more consequent mistreatment could happen again. Gaia instructed her Titan children that Uranus had to be stopped, and presented them with a sickle she had made out of flint for them to destroy him with. Only the youngest male, Cronus, accepted his mother's wish. He had grown to despise his father over his mistreatment of his mother and fellow brethren. Uranus was true to form, and soon wished to exercise his sexual privileges on Gaia. Cronus took action and swung the sickle at Uranus, not only cutting off his testicles, but also cutting him off from earth and exiling him to the sky forever. The Titans released the Cyclopes and the Hecatonchires, and made Cronus (Jupiter) the King of the Gods, effectively marking the start of the Golden Age.
When Cronus threw his father's testicles to the oceans below, it was said the waters churned and turned into white foam. This marked the creation of Aphrodite (also known as Venus), who was to become one of the most influential Goddesses of all time, the Goddess of Love and Beauty. There was even more surprises to come. The blood and semen that flowed during the attack on Uranus led to Gaia having further offspring, this time to all female Goddesses, the powerful Erinyes. They were also referred to as the Avenging Furies, who ensured justice was delivered to all evil doers and murderers. They were then followed by even more offspring, the ash tree Nymphs known as the Meliae.
