About Ugallu

Storm-Demons at the Threshold

Ugallu ('big weather-beast') appear in Neo-Assyrian palace and ritual art as lion-headed, donkey-eared figures with daggers, paired with other apkallu and genii who guard doorways. Incantation series name them among the storm-helpers of Adad and as house protectors who can also threaten.

They are a type, not a named novel villain. The clay and the doorway are the primary sources.

Protective figures

Neo-Assyrian ritual texts describe burying clay figures of ugallu and other protective beings in boxes under the floors and at the doorways of houses and palaces, and many such figurines have been excavated. Wall reliefs from Ashurbanipal's palace at Nineveh show ugallu with raised daggers. Frans Wiggermann's study Mesopotamian Protective Spirits (1992) remains the standard account.
