A rabisu is a type of Babylonian Demon who lurks at the thresholds of homes, waiting to attack humans. Rabisu means “the ones that lie in wait.”
The rabisu were deeply feared in Babylonian times. Inverted bowls inscribed with magical charms were placed at the corners of foundations in an effort to trap and contain them. (See Incantation Bowl.)
An ancient inscription about them says that doors and bolts will not stop them. They can glide into doors as Serpents do and enter through windows as the wind does. Rabisu also perch on rooftops waiting to devour newborn infants. Not all rabisu are evil; some are good.
