IV-century Milan witnesses the coexistence of a fervent Christian and pagan cults, among which the ones dedicated to Cybele and Mitra. Ritual objects from that time, such as the patera of Parabiago, for pagan devotion, and the Capsella of Saint Nazaro (now at Museo Diocesano of Milan), for Christian devotion, are evidence of how different cults could exist and be celebrated at the same time. Not much later, in the second half of the IV century, Milan entered the era of bishop Ambrose, characterized by a strong rejection of paganism that leads to its complete abolishment.
