Professor Jeremy Johns is principally interested in the relationship between Islam and Christianity in the medieval Mediterranean as it is manifested in material and visual culture.
His research has focused upon the archaeology of the transition from late antiquity to early Islam in the Levant and, especially, upon the archaeology, history and art history of Sicily under Islamic and Norman rule, from the Muslims’ conquest of the island in the ninth century to the destruction of the Islamic community of Sicily by Frederick II in the 13th century.
