Nanna-Suen’s Journey to Nippur
Nanna-Suen left Ur and travelled towards Nippur in Maiddaḫedu, his pure boat. The boat was elegant, as its name declared. He took with him the shining ladies, who wore rays of light and were adorned with vigour. He travelled as Nannar, whose divinity was very great. He made his way upstream along the Araḫtu, the channel that brought prosperity.
When he drew near to the quay of the Red Gate, he spent the night at the city gate of Uraš. Bulls were slaughtered, and sheep were butchered. Apricots were dedicated, and other offerings were scattered. Incense was burned, and the scent of sweet resin covered the sky like a thick mist. Torches were raised, and the night shone with light. The district blazed for a distance of one league.
The king summoned those who would address prayers to the son of Bel. The vast peoples bowed in humility and kissed the ground. Nanna-Suen then reached Nippur and presented gifts to Enlil and the gods. Enlil and the gods granted blessings to Nanna-Suen and to Ur. The journey ended with the god and his city placed under their blessing.
