Lilin

The category of the lilin in Jewish and related traditions is traced in the sources to older Mesopotamian spirit categories. Sources link the Hebrew forms לִילֵי / לִילִין (lilin) to Akkadian lilû (a class of spirits) and to the female forms lilītu / ardat-lilî (wind-demons/ghosts). Jewish texts present lilin as related to or descended from Lilith—sometimes as male counterparts or as her offspring—and they appear in late antique ritual and literary contexts (e.g., 2 Baruch's lamentation summons 'Lilin, come you from the desert'). The archaeological and textual incantation-bowl corpus of late antiquity (Sasanian-period Mesopotamia) shows lilin being named, bound, and sealed in household magic, indicating a syncretic development from Mesopotamian demonology into Jewish and local magical practices.

Descriptions vary across the sources. Some summaries (modern reference to the compiled corpus) describe lilin as human in form with wings; other variant descriptions in the literature note an otherwise bald visage with hair covering other parts of the face and body. Incantation-bowl formulas record lilin appearing to people in human likenesses—specifically 'appear to men in the likeness of women, and to women in the likeness of men'—suggesting either shape-changing or presentation in opposite-gender guises in the magical texts.

Across Talmudic, targumic, apocalyptic, and incantation-bowl sources, lilin are depicted primarily as nocturnal spirits that sexually accost humans (bowls and rabbinic anecdotes describe coupling with humans and producing spirit-offspring), cause terror and household affliction, and enter into relationships with people that ritual specialists treat as contractual or legal ties. They are numerous and routinely subject to binding or sealing by higher ritual authorities (e.g., bowl formulas that adjure seals or invoke named demon-kings), indicating they are powerful enough to menace households but not sovereign over divine or demonic order.
