The Myth

The Udug is an ambiguous class of demons in ancient Mesopotamian mythology, found in the traditions of Sumer, Akkad, Assyria, and Babylonia. The beings were associated with the underworld, Kur, and were distinct from the dingir, the divine beings of Mesopotamian religion.

The appearance of the Udug is deliberately difficult to define. No certain visual representation has been identified, and ancient descriptions emphasize that the demon is essentially nameless and formless. An Old Babylonian incantation describes the Udug as one who, from the beginning, was never given a name and never appeared in a definite form.

Descriptions of the evil Udug instead focus on its terrifying supernatural characteristics. It is described as having a towering stature, a malignant appearance, a dark or pitch-black shadow, and no light within its body. It hides rather than standing openly, its claws drip with bile, and it leaves poison behind it. Its arms enclose its victim, while its terrifying battle cry is so powerful that it cannot be restrained.

The Udug could attack and afflict human beings, particularly through disease and supernatural possession. Its presence could bring painful illness into the body, while curses, poison, evil forces, and other forms of supernatural harm were attributed to its influence.

The Udug is especially prominent in the Udug Hul incantations, ancient Mesopotamian texts concerned with the exorcism of evil Udug. These texts describe the demon as a source of illness and suffering and place the exorcist in the role of removing the supernatural affliction and restoring the victim.

The word Udug was not always restricted to one precise type of demon. It could be used more broadly for demons as a whole, making the identity of an individual Udug difficult to distinguish from the wider world of Mesopotamian supernatural beings.

The Udug was also associated with other demons, including the Gallû and Lilu. Some traditions additionally connect the name with Hanbi, a mysterious figure described as the father of Pazuzu and associated with evil forces, although little is known about Hanbi himself.

The essential nature of the evil Udug was therefore not a particular physical form but its supernatural presence: darkness, poison, terrifying sound, possession, disease, and the unseen forces that afflicted human beings.

The Myth

The Palm Tree King was one of the strange and monstrous beings known as the Slain Heroes in ancient Sumerian mythology. These creatures appear in the epic Lugale, which tells the story of the warrior god Ninurta battling monstrous enemies to recover the stolen Tablets of Destiny.

The Slain Heroes served the monstrous being Imdugud, also known later as Anzu, who had stolen the divine Tablets of Destiny from the god Enlil, ruler of wind, storms, and the heavens. Ninurta set out to defeat these creatures and reclaim the tablets.

Very little survives about the Palm Tree King compared to the other monsters in the epic. Ancient texts mention him among the creatures allied with Imdugud, but few details describe his appearance or powers. His unusual name suggests a connection to sacred trees, fertility, or the wilderness of southern Mesopotamia.

Unlike many of the other Slain Heroes defeated by Ninurta during his campaign, the Palm Tree King may have escaped destruction. Some interpretations of the surviving myths describe him as the only monstrous servant of Imdugud not clearly slain in battle.
