Scarce two volume work on Babylonian Cuneiform texts translated from the originals, with transliterations, vocabulary and notes, etc. Volume I. "Evil Spirits". Volume II "Fever Sickness and Headache, etc". A unique collection of magical spells and incantations to ward off evil demons, sicknesses, and more. Translated from Babylonian cuneiform tablets with most of the spells having their origins in Sumerian demonology. This valuable work made a substantial contribution to modern knowledge of ancient Babylonian demonology and magical practices. Thompson states in his introduction: "From the earliest times Eastern races, in common with the rest of mankind, have always held a firm belief in the existence of evil spirits, ghosts, and all kindred powers. The phenomena of death, the mystery of disease and sickness, and all the other events of common occurrence in daily life gave rise to speculations about the unseen world, which gradually led to a distinction, although slight at all times, between good and evil spirits. The early Semitic people of Babylonia, whoever they may have been or wherever they may have migrated from, found a theology ready to their hands in their adopted country, which they took over from its primitive inhabitants the Sumerians, doubtless grafting to it many of the beliefs of their forefathers. To the latest times, down to a century or two before the Christian era, they retained the doctrines in their original language, making interlinear translations of them for use in the temples and among the doctors, and it is owing to this that we can speak with tolerable certainty on many points of the early religion of Babylonia."

Volume 1 concerns magical incantations dealing with evil spirits while Volume 2 focuses on purification rituals, protection against disease, and descriptions of supernatural beings, and additional protective charms against evil spirits. The work includes transliterations and explanatory notes, and was designed to accompany earlier British Museum publications of cuneiform texts from the seventh-century BCE Library of Ashurbanipal at Nineveh.
