Eustorgius of Milan

Saint Eustorgius of Milan was Bishop of Milan in the fourth century and a defender of the true faith against the Arians. The sources do not agree on the years: some place him as bishop in 315 and reposed around 331, others make him bishop from 343 to about 349.

According to tradition he was of Greek birth and noble. He was an envoy of Milan and was elected bishop at the death of Protasius in 343. He travelled to Constantinople to have his election confirmed by the emperor, who is said to have given him the relics of the Magi, which he brought to Milan. He held two synods, in 345-346 and 347-348, and began the building of churches and basilicas in the city. Saint Athanasius called him a "defender of the faith" and named him among the opponents of Arianism, and Saint Ambrose gave him the title of confessor.

In Milan five churches bear his name, among them the Basilica of Sant'Eustorgio. He is commemorated on 18 September, as a saint of the undivided Church, by the New Calendar.
