A Dionysia makes extensive use of paintings from the web site WikiArt. All the paintings in the film are posted on Flickr and are presented in the screenplay. The filmmaker’s collection of paintings from WikiArt is available in several Flickr albums.

(The paintings marked “public domain” are public domain in the United States according to the filmmaker’s understanding, but you would need to verify that situation yourself if you want to distribute the paintings yourself.)
