"The Fantastic in Art and Fiction" is a great image collection put together by the Cornell Institute for Digital Collections. These images are from the 'division of rare and manuscript collections' at the university library.
About the site: "...This image-bank provides a visual resource for the study of the Fantastic or of the supernatural in fiction and in art. While the site emerges from a comparative literature course on the topic at Skidmore College, it is also intended to open the door to consideration of some of the constant structures and patterns of fantastic literature, and the problems they raise. In this sense, the materials presented here may find a use among students in a variety of disciplines."
The categories: Angels and Demons, Danse Macabre, Weird Science, Bestiary, the Marvelous, the Grotesque, Posession and Insanity, Fantastic Space, Freaks Monsters & Prodigies.
