Here’s video of the Way Public Library‘s presentation of “Theatre of the Occult” featuring speaker Edmund B. Lingan PhD. In his lecture, Lingan explored the role of theater to the seeking of the occult during the 19th and mid-20th century. The program was at the Way Public Library, part of its “Everyday Humanities” series. Linigan is an associate professor of theater and film at the University of Toledo.
