This is a vintage illustration of a demonic figure, likely from a historical bestiary or occult text. The demon is depicted in a dynamic pose, with arms outstretched and one leg raised, suggesting movement or a threatening gesture. It has a humanoid body covered in dark fur, with a grotesque face featuring horns, pointed ears, and a menacing expression. A serpentine creature is coiled around its waist, possibly symbolizing power or a connection to the underworld. The background is a simple, pale green with a few blades of grass, providing minimal context. The image is framed by a dark green border with handwritten text in an old-fashioned script, adding to its antique and esoteric feel. The overall style is reminiscent of medieval or Renaissance woodcuts or engravings, with a focus on detailed linework and expressive character design.
