Catholic Encyclopedia (1913)/Diocese of Adria
An Italian bishopric, suffragan to Venice, which comprises 55 towns in the Province of Rovigo, and a part of one town in the Province of Padua. Tradition dates the preaching of the Gospel in Adria from the days of St. Apollinaris, who had been consecrated bishop by St. Peter. The figure of this Bishop of Ravenna has a singular importance in the hagiographical legends of the northeast of Italy. Recent investigation has shown that even if Emilia, Romagna, and the territory around Venice were Christianized and had bishops (the two facts are concomitant) before Piedmont, for example, still their conversion does not go back beyond the end of the second century. (See Zattoni, Il valore storico della Passio di S. Apollinare e la fondazione dell episcopato a Ravenna e in Romagna, in the Rivista storico-critica delle scienze teologiche, I, 10, and II, 3.) The first bishop of Adria of whose name we are positive is Gallonistus, who was present at a synod in Rome (649) under Martin I (Mansi, XII). Venerable Bede, in his Martyrology, mentions a St. Colianus, Bishop of Adria, but we know nothing about him. Amongst the bishops of Adria is the Blessed Aldobrandinus of Este (1248-1352). This diocese contains 80 parishes; 300 churches, chapels, and oratories; 250 secular priests; 72 seminarians; 12 regular priests; 9 lay-brothers; 90 confraternities; 3 boys schools (97 pupils); 6 girls schools (99 pupils). Population, 190,400.
