In the very beginning the gods distributed the whole earth between themselves. The god Poseidon, the master of the waters, received as his lot an area later known as Atlantis. In the area allotted to him lived a young woman, called Cleito. Poseidon, the mighty God of the sea, fell in love with this mortal woman. She was living alone on a small hill near the sea because her parents had recently died. To safeguard her he created two rings of land and three rings of water around the hill top.
Together they had five pairs of twin male children, in total ten sons. Because they were ten siblings, the territory that Poseidon had received was divided up into 10 portions. The first born twin was named Atlas, after him the Atlantic Ocean and the Empire of Atlantis got its name. He also received the dwelling of his mother – which would become the capital city of Atlantis - and the surrounding allotment, which was the best. Poseidon made Atlas the ruler, the king of kings – his nine brothers were made kings and Poseidon gave them rule over many men and a large territory. This is – according to Plato - how Atlantis was established.
