The Epic of Gilgamesh
"Now you, Gilgamesh, let your belly be full!
Be happy day and night,
of each day make a party,
dance in circles day and night!
Let your clothes be sparkling clean,
let your head be clean, wash yourself with water!
Attend to the little one who holds onto your hand,
let a wife delight in your embrace.
This is the (true) task of mankind(?)." (Old Babylonian Supplement at 10.72)
