Rabisu

In Akkadian mythology the Rabisu ("the lurker"; Sumerian 𒉺𒁽 Maškim, "deputy, attorney"[1]), or possibly Rabasa, are vampiric spirits, daimons, or demons.

Assyriologist Reginald Campbell Thompson published the seventeenth volume of Cuneiform Texts from Babylonian Tablets and a two-volume series Devils and Evil Spirits of Babylonia.

One of the main reasons people often mistake the Rabisu to be intrinsically evil is because of modern connotations of the word "demon".

[5] The book The Religion of Babylonia and Assyria by Theophilus Pinches describes the Rabisu as being "the seizer" which is "regarded as a spirit which lay in wait to pounce upon his prey".

“In Gen 4:7, Robes, which is routinely thought to denote a demon [in which] Akkadian texts indicate that the rabisu is a neutral being that is nothing other than a current of wind dispatched by the deities to perform certain duties”.

[8] The Sumerian and Akkadian deity, Enlil, a major god of the earth, sky, atmosphere and storms is the sender of the “windy beings” known as Rabisu.

Whether the message entailed good or bad things for the receiver was not a reflection upon the Rabisu but rather the consequence of human actions, which themselves were of different moral character.

The story of the Curse of Agade ends with the complete destruction of the city of Akkad, Enlil triumphing over the earthly human domain.

[10] The story of the Curse of Agade is similar to a myth of the "lost city" of Ubar, sometimes referred to as "Atlantis of the Sands," located farther to the south in southeastern Oman.

In the 1977 grimoire Simon Necronomicon by Peter Levenda, which draws upon a blend of real myths including Sumerian and fictional creations, Rabisu are described as ancient demons.

A squad of American Marines find themselves trapped in an ancient Mesopotamian temple after a raid on a local village in search of weapons goes awry.

Concurrently, bat-like vampiric creatures awaken from their millennia-long slumber to roam the temple and stalk and terrorize their newfound human prey.
