[4] In the Song of Ullikummi, known from poorly preserved fragments of a Hurrian original and a more complete Hittite translation, the eponymous monster is placed on his right shoulder by Irširra (perhaps to be identified as goddesses of nursing and midwifery[5]), the servants of Kumarbi, to let him grow away from sight of allies of Kumarbi's enemy Teshub, such as the sun god Šimige.
[3] Later the god Ea seeks him out in order to find out how to defeat Ullikummi, and asks him if he is aware of the identity of the monster growing on his back.
As it turns out, Upelluri did not notice the new burden at first, but eventually he starts to feel discomfort, something that according to this text he did not experience even during the separation of heaven and earth.
The rest of the tablet is broken, and the next preserved scene does not feature Upelluri anymore.
[2] It has been pointed out that the later Greek Atlas plays a cosmological role similar to that of Upelluri.
