The first bronze door on the left of the façade was created by the Israelite sculptor Arrigo Minerbi (Ferrara, 1881 - Verona, 1960). After over ten years of work, the door was inaugurated on 5 June 1948: the panels tell the story of early Christianity and the persecution of Christians up to Constantine's Edict of Milan (AD 313). It is made up of 12 panels across two registers, of which the lower shows legendary episodes, while the upper historical ones. In the centre is the transcript of the Edict of Milan.
