Now there is one suggestion that deserves a passing notice, and that is, the possibility of St. Martin himself having been the founder of the church; even in a closer sense than by merely sending masons from his monastery, as he did to St. Ninian. In the constant interchange of communication between Britain and Gaul, not only for commercial but for military purposes, it may have happened that Christians had migrated, or been transferred, from Tours to Kent--and for the benefit of Christian soldiers, St. Martin, once a soldier himself, may have urged the erection of a church. It is unnatural to suppose that St. Martin, who travelled over a great part of Gaul, did not in some way associate himself with Britons, with whom he would have been brought into contact. We know this, at any rate, that during the latter year of his episcopate he exercised great influence over the Emperor Maximus and his Empress--and Maximus had resided for several years in Britain, was proclaimed emperor there in 383, had thence invaded Gaul with a fleet and army, which were long afterwards remembered as the "emigration of a considerable part of the British nation," and finally settled at Trêves, where he was more than once visited by St. Martin. Some of these British emigrants or soldiers would very naturally have returned to their native country and brought Christianity with them. There is no conclusive reason why St. Martin himself, either prompted thereto by Maximus, or yielding to the entreaties of Britons whom he met at Trêves or elsewhere in Gaul, should not have visited Canterbury in person, and there founded the church. It is remarked by Haddan and Stubbs that "it was a peculiarity of British Christians that churches were not dedicated to any saint already dead, after the fashion then beginning to be common, but were called by the name of their living founder." Or the original dedication made by St. Martin (acting either directly or indirectly) may have fallen into popular disuse, and been supplanted by his own name, as was the case with the church of St. Gregory on the Coelian Hill, which St. Gregory had dedicated to St. Andrew, but which soon after came to be called after himself, though he was not buried there. And attention may be directed to instances of a similar kind at Rome, where the names of founders lingered on in churches like the Basilica Constantiniana, Basilica Liberiana, and St. Lorenzo in Damaso. We may also note the fact, that a chapel in Canterbury Cathedral, originally dedicated to St. Peter and St. Paul, soon acquired the name of its founder, St. Anselm, and even the great Cathedral itself, the "Church of Christ," was popularly known in the Middle Ages as the Church of St. Thomas. These latter instances are not indeed exactly parallel, because the relics of the name-saints were actually buried in these places, but they may be quoted as showing how readily the original dedication may have been subsequently changed;
