Our view will partly depend on the latitude we may feel justified in giving to the expression _post paucos annos_. It might be held that his ordination by Amator preceded his return to Britain; or it might be held that he was not ordained at Auxerre till after his visit to Britain, so that he would have returned to Gaul before A.D. 418. The second alternative seems the more probable,[384] and it agrees with the tradition (Muirchu) that he went to Auxerre to study _after_ his visit to Britain. His choice of Auxerre, combined with the circumstance that it was a bishop of Auxerre who afterwards took a prominent part in helping the orthodox British against Pelagianism, suggests that relations of some intimacy were maintained between Auxerre and some of the British sees. When Patrick, in Britain, made up his mind as to the destination of his life, he would have gone to Auxerre with recommendations from his friends. It seems most likely that his connexion with Auxerre should have originated in this way. The tradition as embodied in Muirchu represents him as remaining at Auxerre till his departure for Ireland, and though it might easily be erroneous, it is, so far as it goes, against the possible theory that Patrick’s sojourn at Lérins is to be placed after his visit to Britain. But we have another piece of evidence which seems to me decisive, namely, one of the so-called _Dicta Patricii_. See Excursus 6, _ad fin._ The argument for placing the sojourn at Lérins before the return to Britain may be summed up thus: (1) the reminiscence of Patrick’s wanderings almost certainly refers to his wanderings after his escape, and there can hardly be any doubt that the “islands in the Tyrrhenian Sea” mean the islands of Lérins, in view of the definite tradition (Tírechán, 302₂₄) that he stayed in the _insola Aralanensis_; (2) this date for the retreat to Lérins supplies the much-needed explanation of his delay in returning home. The following chronology, then, may be a rough approximation:— A.D. 411/2 escape from his ship-companions; A.D. 411/2-414/5 at Lérins; A.D. 414/5 returns to Britain; A.D. 415/6 goes to Auxerre; A.D. 416-8 is ordained by Amator; A.D. 418 death of Amator, who is succeeded by Germanus; A.D. 418-432 Patrick remains at Auxerre, as deacon; A.D. 429 Germanus goes to Britain to suppress the Pelagian heresy; A.D. 431 Palladius consecrated bishop for the Irish Church; A.D. 432 Patrick consecrated bishop by Germanus. 6. _The Escape to Gaul.
