The Asag

Also called Asakku

A demon that fathers an army out of the mountain stones and makes fish boil in the rivers — and whose name becomes the ordinary Akkadian word for a class of illness.

InfernalDemon of Sickness and StoneMesopotamian

In Lugal-e the Asag is a presence rather than a person: its heat scalds the rivers, the fish boil, and it begets an army by coupling with the mountain, so that Ninurta has to fight the stones as well as the thing that made them. It is one of the oldest adversaries in the corpus and among the least anthropomorphic.

What happens to the name afterwards is the part worth recording. Asakku passes into Akkadian as a term for a class of sickness rather than for an individual, and turns up in the incantation literature this corpus now carries as a category of affliction. That is the same demotion the Levantine material shows repeatedly — Resheph becoming a word for plague — running here in Mesopotamian instead.

Scalds the rivers so that the fish boil, fathers an army of stones on the mountain, and is destroyed by Ninurta.

Udug-hul (Evil Utukku)c. 1800–600 BCE
asakku

The name after the demotion. The monster Ninurta kills in Lugal-e is by this material an ordinary word for a class of illness, addressed in the same breath as the other afflictions the series is aimed at. A defeated adversary surviving as a medical term is the Resheph pattern in a second language.

Common questions

Which texts mention The Asag?

ColossiansOne records 2 texts naming The Asag: Lugal-e (Ninurta and the Asag) and Udug-hul (Evil Utukku). The earliest is Lugal-e (Ninurta and the Asag) (c. 2100 BCE), which gives the name as Asag.

What rank is The Asag?

The Asag is ranked as Demon of Sickness and Stone in Lugal-e (Ninurta and the Asag). Rank in this material is a claim made by a particular text, not a fixed property of the figure.

How else is The Asag spelled?

The name appears as Asag, asakku and Asakku. Variation on this scale is the norm: these names cross Ugaritic, Hebrew, Greek, Latin and vernacular transmission, and each step reshapes the spelling. Every profile records the name as each text gives it.

What is The Asag said to do?

The sources credit The Asag with 2 distinct powers or offices, including Causes Sickness and Burns & Slays. Each is attributed on the profile to the text that claims it. ColossiansOne describes what the texts say; it does not endorse the claims or reproduce them as instruction.

How old is The Asag?

The earliest attestation in this corpus dates to c. 2100 BCE. That is when the name first appears in a surviving text, which is a lower bound rather than an origin — a figure known from three tablets was probably named in many more that did not survive. The Asag is classified as infernal in ColossiansOne.
