“This passage reminds one of the old Mesopotamian concept—and I am convinced it is a Mesopotamian concept, not a mere invention of modern scholarship—according to which a (mythical) ruler is thought to cohabit with a goddess or with her priestly incarnation.
(This is a much disputed issue, best known under the heading “Sacred Marriage” concept. What is interesting here is the feature of a divine-human interaction in the sexual life and the consequences thereof. We are not concerned here with the hypothesis of a purely metaphorical interpretation or with a possible actualization in an alleged ritual.
For a comparative evaluation of this topic see P. Lapinkivi, The Sumerian Sacred Marriage in the Light of Comparative Evidence (SAAS 15; Helsinki: Neo-Assyrian Text Corpus Project, 2004.)

Accordingly, the kings of the Ur III empire depict themselves in their hymns as divine scions, as sons of the mythical ruler Lugalbanda and the Goddess Ninsu(mu)na-k. In the present context it is not without interest that these kings were thus becoming “brothers of Gilgamesh,” profiting somehow from the hero’s legendary fame.
The divine sonship, however, can be traced back to the middle of the third millennium. An Old Sumerian ruler of the south Mesopotamian city state Lagash depicts himself in his text as follows:
“(The god) [Ni]n[gir]su-k [imp]lanted the [semen] for (the ruler) E’[a]na-tum in the [wom]b . . . rejoiced over [E’anatum]. (The goddess) Inana-k accompanied him, named him “In the E’ana (temple) of Inana-k from (the sacred precinct) Ibgal I bring him (= E’ana-Inana-lbgal-akak-atum)” and set him on the legitimising knees of (the mother goddess) Ninchursag(a). Ninchursag(a) [offered him] her legitimising breast.”
(Ean 1, 4:9-12 (H. Steible, ed., Die altsumerische Bau-und Weihinschriften [2 vols.; Freiburger altorientalische Studien 5; Wiesbaden: Steiner, 1982], pp. 1:122) RIME 188.8.131.52, 4:9-12.
See D. Frayne, ed., Presargonic Period (2700-2350 BCE) (RIME 1; Toronto: University of Toronto Press, 2008), pp. 129-30.)
“Ningirsu-k rejoiced over E’anatum, semen implanted into the womb by Ningirsu-k. Ningirsu-k laid his span upon him, for (a length of) five forearms he set his forearm upon him: (he measured) five forearms (cubits), one span! (to the reconstructed measurements of this period ca. 2.72 meters). Ningirsu-k, out of his great joy, [gave him] the kin[gship of Lagash].”
Hence, the ruler is the one “who has strength,” a precondition for his successful rule.
The aforementioned size of 2.72 meters makes just a small giant. However, this size is an outward sign designating someone who transgresses human measurements and norms.
Accordingly it became possible to attribute to such an extraordinary ruler a sort of functional divinity, as can be corroborated by several additional arguments.
We can therefore say that the ruler is perceived as an Avatar, a manifestation of the state god Ningirsu-k.”
