Christian–Islamic encounters through religious arts, architecture, and material culture in the medieval era

The coexistence of Christianity and Islam in the medieval Mediterranean led to an interchange of knowledge in architecture and material culture that went well beyond religious and geographical boundaries. The use of Islamic objects in Christian contexts, the conversion of churches into mosques, and the mobility of craftsmen are only some manifestations of this process. From crosses found in mosques to European-Christian coins with pseudo-shahada inscriptions, medieval material culture is rich with visual evidence of the two faiths intermingling in both individual objects and monuments.
