Muirchu’s account of the events preceding Patrick’s ordination as bishop has certain difficulties which involve an important question. Patrick, we are told, had left his home in Britain for the purpose of visiting Rome (_ad sedem apostolicam uisitandam_, etc.), to receive instruction there for his life-work in Ireland. But he halted on his way at Auxerre, and remained there “at the feet” of Germanus. Then when the right time came and new visions warned him: _coeptum ingreditur iter ad opus in quod ollim praeparatus fuerat utique aeuangelii_ (272₁₀). What is the meaning of _coeptum iter_? The journey which Patrick had begun was the journey to Rome, which had been interrupted at Auxerre. Germanus sends with him a presbyter, Segitius, as a companion and “witness.” Then comes a notice of the unsuccessful mission of Palladius by Pope Celestine; but the transition to this is curious. _Certe enim erat quod Palladius_, etc., is the text of the Armagh MS., while it seems probable that other MSS. had _certi enim errant_[403] which gives sense. Having heard of the death of Palladius, Patrick and those who were with him _declinauerunt iter_ to be ordained by “Amatorex.” Assuming that they were on their way to Rome, it is clear that Muirchu did not suppose that they ever reached Rome; for, if he did, he could not have failed to say so. Accordingly, on this view, we have to suppose that the decisive news overtook Patrick somewhere between Auxerre and Rome, and that Patrick turned about and retraced his steps, making a divagation for the purpose of being ordained by “Amatorex.” But if we read the whole narrative carefully up to the embarkation, we can hardly fail to see that in the writer’s conception of what happened there was no reversal of direction. The only natural interpretation of Muirchu’s meaning is that, met by the news about Palladius, Patrick turned from his direct route for the sake of ordination, and then resumed it. In other words, he was on his way to Ireland. But it can be proved definitely that this was Muirchu’s conception. In his table of contents to bk. i. we find a statement which throws light on _coeptum iter_. We find the items: De inuentione sancti Germani in Galliis et _ideo non exiuit ultra_: De _reuersione eius de Galliis_ et ordinatione Palladii et mox morte eius. Here it is (1) expressly stated that Patrick did not proceed beyond Gaul (as he had intended), and (2) implied that the journey which he undertook in the company of Segitius was a _reuersio_ to Britain or Ireland.
