Protasius (Italian : Protaso) was Archbishop of Milan. He is honored as a saint in the Catholic Church, with his feast day celebrated on 24 November, the day of his death. [1]
Almost nothing is known about the life of Protasius. He was elected bishop of Milan in 328, and served until his death, about 343. [2]
Athanasius of Alexandria, in his Apologia ad Constantium [3] , mentioned that Protasius was with him when he spoke to the Roman Emperor Constantius II; this episode can be dated about 342 or 343. [4] In 343, Protasius attended the Council of Sardica and signed its decrees, standing up against the Arians and supporting the faith of the Council of Nicaea. [2]
Protasius died about 343 on 24 November. His body was buried in Milan in the Church of San Vittore al Corpo (Saint Victor Maurus), where it is venerated still. A late tradition, with no historical basis, associates Protasius with a Milanese family, the Algisi. [4]
