Enheduanna (c. 2300-2225 B.C.) is the first author of a written work whose name is known.
She was the daughter of the Akkadian ruler Sargon the Great, and was also a high priestess of Inanna in the city of Ur in Mesopotamia. En means high priestess, so her name could also be written as High Priestess Hedu-anna. Although she was born in Akkad, she wrote in Sumerian.
45 of her hymns and songs are known. 42 of them are temple hymns of Sumer and Akkad, and 3 are long works about the goddess Inanna: Inninmehusa, The Myth of Inanna and Ebih; Inninsagurra, Stout-Hearted Lady; and Ninmesarra, Lady of all the Divine Powers.
Excerpt from Inninsagura ("Stout-hearted Lady")
To destroy, to build up, to tear out and to settle are yours, Inanna,
To turn a man into a woman and a woman into a man
are yours, Inanna,
Desirability, libido, to have goods and property are yours, Inanna,...
Business, great winning, financial loss, deficit are yours, Inanna,
Information, instruction, inspection, to look closely, to approve are yours, Inanna,...
To build a house, to build a woman's chamber, to have implements,
to kiss the lips of a small child are yours, Inanna,
Swiftness, foot race, to attain desire are yours, Inanna,
To interchange the brute and strong
and the weak and powerless is yours, Inanna,...
To give the crown, the chair and the scepter of kingship is yours, Inanna.
Excerpt from Ninmesarra:
That you annhilate rebelling territiories , shall be known!
That you roar against the enemy lands, shall be known!
That you crush the leaders, shall be known!
That you devour corpses like a predator, shall be known!
That your glance is terrible, shall be known!
That you raise your terrible glance, shall be known!
That your glance is sparkling, shall be known!
That you are unshakable and unyielding, shall be known!
That you always stand triumphant, shall be known!
