Biography

Sargon united the kingdoms of Sumer and Akkad, including parts of modern Syria, Iraq, Iran and Turkey. His early life is largely a mystery. One ancient Sumerian legend states that he was the son of a high priestess and was floated in a basket on the Euphrates before being rescued and raised by a water-drawer named Aqqi who adopted him. (compare: the stories of Maui and Moses). He worked in Aqqi's orchards and became a favorite of the goddess Ishtar.

It is not known how a man of such unprepossessing beginnings was able to attain his position, but the great king rising from obscurity is a common theme in ancient mythology, serving to emphasize his natural and god-given authority (especially when coupled with a divine parent), and kings would cultivate such tales to enhance their prestige, in the same was as modern politicians encourage stories of their rise from humble origins.
