In Did Greeks and Romans allow for belief in only some of their gods?, Igidallru is mentioned:
Here is for example Odysseus killing the Cyclops, I meant Nergal killing Igidallru
As a comment points out, this apparently is the only reference to "Igidallru" on the internet:
As far as I can see, this apparently is the only place on the internet that the word "Igidallru" appears. Perhaps it has another transliteration? – mattdm
Gibet then offers some alternative transliterations:
@mattdm The internet is not the de facto source This is just the source of brilliant shortcuts. Igidalru/igedelu/igetela appears, fairly quite rarely in some Akkadian stories It was identified by René Labat, just because in Sumerian (not Akkadian) igi.dili means precisely one eye. - Gibet
Unfortunately, none of the proposed alternatives produced any usable results.
What or who is Igidallru?
