From Aēšma to Asmoday: The Transformation of Asmodeus from Iranian Demonology to Jewish Literature and Western Occult Tradition

This article examines the historical transformation of Asmodeus across Iranian, Jewish, Christian, and early modern European religious literature. Beginning with the possible relationship between the Zoroastrian figure Aēšma and the demon Asmodeus in the Book of Tobit, it traces the development of the figure through the Dead Sea Scrolls, rabbinic literature, the Testament of Solomon, and the Ars Goetia. Particular attention is given to the changing portrayal of Asmodeus as a destructive spirit, an adversary associated with marriage, a powerful figure in Solomonic demonology, and a demon subsequently connected with lust. The study distinguishes linguistic connections from literary dependence and considers how religious traditions adapted inherited supernatural figures to changing theological and cultural environments. It argues that Asmodeus should be understood not as a single unchanging figure, but as a character whose identity and functions developed across centuries of textual transmission and religious interpretation.
