Saint Delphinus, Bishop
The first mention of this, the second bishop of Bordeaux, is his presence at the Synod pf Saragossa in the year 380, when the Priscillianists and other heretics were condemned. The greatness and holiness attaching to the name of Delphinus are chiefly a matter of inference from the facts that he was a valued correspondent of St. Ambrose and had strong influence with Pontius Meropius Anicius Paulinus, better known as St. Paulinus of Nola. The conversion of the last-named was principally the work of his wife and St. Delphinus, who eventually baptized him. Five of the letters of Paulinus to his spiritual benefactor have been preserved and witness to the respect in which he held St. Delphinus.
Besides St. Ambrose and St. Paulinus (the latter is best consulted in the Vienna Corpus Scriptorum, vol. xxix, nn. 10, 14, 19, 20 and 35), Sulpicius Severus also makes mention of Delphinus in his Chronicle (bk ii, ch. 48). A Vie de St. Delphin was published by Fr. Moniquet in 1893, but it is severely criticized in the Analecta Bollandiana, vol. xii, pp. 460-462.
