MASSIMINO, bishop of TREVIRI, saint. - Born at Silly (Sigillicum) in Aquitania, of a noble family, toward the end of the third century, he was directed toward his studies by Bishop St. Agricio, whom he succeeded in the episcopate around 332.
He received St. Athanasio (v.) during his two years of exile in his city (336–38). In 341 he also received Paolo, the exiled patriarch of Constantinople, and subsequently endeavoured to have him restored to his see. In 342 he rejected four Arian bishops, who had come from Antiochia to win over the Emperor, and persuaded him to reject their insidious proposals. In 343, together with Pope Giulio I and Osio, bishop of Cordova, he obtained from Costante the convocation of a Synod at Sardica in Illyricum against Arianism, and subscribed its acts; for this reason the Arian Synod of Filippopoli condemned him, together with Giulio I and Osio.
The year of his death is unknown; but by 347 Paolino had already succeeded him. St. Gregorio di Tours calls him « episcopus potens in omni sanctitate » (Historia Francorum, I, 37); he was venerated as the patron of Treviri.
In the historical Martyrologies his feast is recorded on 29 May; 12 September is the probable date of a translation of relics.
