I am Culgi, who has been chosen by Inana for his attractiveness.
…
Because I am a powerful man who enjoys using his thighs, I, Culgi, the mighty king, superior to all, strengthened the roads, put in order the highways of the Land.
…
So that my name should be established for distant days and never fall into oblivion, so that my praise should be uttered throughout the Land, and my glory should be proclaimed in the foreign lands, I, the fast runner, summoned my strength and, to prove my speed, my heart prompted me to make a return journey from Nibru to brick-built Urim as if it were only the distance of a double-hour.
— A praise poem of Shulgi (Shulgi A)
