ArtMagick is a collection of art and poetry that roughly dates from after the Enlightenment but before Modernism. While the poetry section is extensive the main draw is the sites extensive art collection, which can be browsed by artist, art movement, title, theme or albums created by the site's users.

Dave's Art Nouveau page - Very cool Art Nouveau themed sketches and paintings by comic and fantasy artists. My faves are Batgirl, Cherry Poptart, and Vampirella. (Some of these aren't safe for work.)
