He has written on spirit possession and exorcism, egodocuments, women’s religiosity, Jewish attitudes towards magic, and, most recently, on the visualization of knowledge. He co-edited The Visualization of Knowledge in Medieval and Early Modern Europe (2020). Chajes’s first book, Between Worlds: Dybbuks, Exorcists, and Early Modern Judaism (2003) was listed by the Wall Street Journal in 2013 as among the top five books ever written on spirit possession, alongside Aldous Huxley’s The Devils of Loudun.
