Chant to him the holy song, the incantation sung in its chambers -- the incantation of Nudimmud: "On that day when there is no snake, when there is no scorpion, when there is no hyena, when there is no lion, when there is neither dog nor wolf, when there is thus neither fear nor trembling, man has no rival! At such a time, may the lands of Šubur and Ḫamazi, the many-tongued, and Sumer, the great mountain of the me of magnificence, and Akkad, the land possessing all that is befitting, and the Martu land, resting in security -- the whole universe, the well-guarded people -- may they all address Enlil together in a single language! ... Enki, the lord of abundance and of steadfast decisions, the wise and knowing lord of the Land, the expert of the gods, chosen for wisdom, the lord of Eridug, shall change the speech in their mouths, as many as he had placed there, and so the speech of mankind is truly one."
Enmerkar, in Enmerkar and the Lord of Aratta, Neo-Sumerian period (ca. 21st century BCE).
