Wagner Free Institute of Science (WFIS) is hosting their second Weeknights at the Wagner talk of the year– just in time for Halloween.

On Thursday, October 25th, join Dr. Elly Truitt, a Harvard and Cambridge-educated historian who specializes in medieval science and medicine, for an illustrated presentation exploring the occult sciences and natural philosophy in the Middle Ages: The Dark Arts in the Dark Ages: A Halloween Program at the Wagner Free Institute of Science.

Dr. Truitt will discuss a number of legendary figures from medieval history, including Gerbert of Aurillac, said to have created a prophetic head and to have sold his soul to the devil; Gerard of York, a bishop believed to practice necromancy; and Albertus Magnus, a great thinker who was posthumously called a sorcerer.
