While Erragal might have been associated with storms and the destruction caused by them, he is chiefly attested as a benevolent deity, for example as an astral god with apotropaic functions.
[7] However, Kynthia Taylor disagrees with Wiggermann and argues that due to the proximity of these two deities in god lists and the fact that Erragal is well attested in texts written in the Emesal dialect of Sumerian it is plausible they developed under similar circumstances, with Erragal originally being an epithet applied to Erra in Emesal texts which eventually came to be viewed as a separate figure.
[9] The first of them is presumed to functionally be a double of Erragal,[10] and based on distribution in known texts might represent an Akkadian spelling of the same name, following the well attested phenomenon of interchange between voiced and voiceless consonants in Sumerian loanwords in this language.
[7] According to Nicla de Zorzi a passage in the section of Enūma Anu Enlil focused on the weather can be translated as an omen pertaining to him, "Erragal will bring hard times to the land".
[7] According to the astronomical compendium MUL.APIN, Erragal and Ninšar corresponded to two paired stars[16] located in the proximity of that associated with "Lamma, the messenger of Baba", a part of a constellation known as "She-Goat",[17] modern Lyra.
[23] A Middle Assyrian text refers to Me-Turan (Sirara) as a cult center of Erragal, though his name might only be used as a stand-in for Nergal in this context, as the latter is well attested in association with this city.
[29] In both the Epic of Gilgamesh (tablet XI, line 102) and the Neo-Assyrian version of Atra-Hasis, Erragal is responsible for "ripping out the mooring-poles" before the flood.
[30] Erragal's role in Mesopotamian literature is limited to these texts, but it has been argued that a reference to these two passages can be found in the myth Erra and Ishum (tablet IV, lines 118–120), where the first of the eponymous gods describes the destruction he is capable of causing: Let me rip out the mooring-pole so that the ship keeps drifting away, Let me break the rudder so it cannot dock at the shore,
Let me tear out the mast, let me rip out its rigging[31]According to a recent publication by Elyze Zomer a further possible reference to Erragal in a similar context also occurs in the text HS 1885+ from Nippur, a "royal epic" (Königsepos) describing the conflict between Gulkišar, the sixth king of the First Dynasty of Sealand, and Samsu-Ditana, with the former portrayed as the protagonist.
