I'm not sure. "Grotesques," maybe. I've always liked the style of the illustrations in materia medica manuals and the Dictionnaire Infernal and such. Strangely, I'm also fascinated by anti-Semitic cartoons, even though I am emphatically not an anti-Semite. The face on the demon was influenced by the exaggerated "wicked Jew" features in anti-Semitic cartoons. I also like calligraphy. The text was influenced by the script in the Voynich MS.
