Sir E. A. Wallis Budge, in Babylonian Life and History, says:
The demons and devils that made the Babylonian’s life a misery to him were many, but the forms of most of them and their evil powers were well known. Most of all he feared the Seven Evil Spirits, who were the creators of all evil. . . . As there were triads of gods, so there were triads of devils, for example, Labartu, Labasu and Akhkhazu. The first harmed little children, the second caused the quaking sickness, and the third turned the face of a man yellow and black. Another triad comprised Lîlû, Lîlîtu and Ardat Lîlī. . . . The Babylonians . . . went to the priest, who often assumed the character of a god, and who exorcised the devils by reciting incantations, . . .—Pages 146, 147 (1925 edition).
