Dessi, or the settlements have all been made at one time, and there seem to have been other settlements in Somerset, Devonshire, and Cornwall.[17] [Sidenote: IRELAND AND THE EMPIRE] General considerations, then, supported by particular fragments of evidence which exist, would prepare us to learn, as something not surprising, but rather to be expected, that, by the end of the fourth century, Christians, and some knowledge of the Christian worship, should have found their way to the Irish shores. Beyond the regular intercourse with Britain, Gaul, and Spain there was the special circumstances of the Irish settlements in south-west Britain—a highroad for the new creed to travel;[18] and the great invasion in the middle of the fourth century, which will be mentioned in the next chapter, must have conveyed Christian captives to Ireland. In the conversion of this island, as elsewhere, captives played the part of missionaries. It will not then amaze us to find, when we reach the fifth century, that men go forth from Ireland to be trained in the Christian theology. It will not astonish us to learn that Christian communities exist which are ripe for organisation, or to find this religion penetrating into the house of the High Kings. We shall see reasons for supposing that the Latin alphabet had already made its way to Ireland,[19] and the reception of an alphabet generally means the reception of other influences from the same source.[20] For the present it is enough to have brought the relations of the Empire to Ireland somewhat into line with its relations to other independent neighbours. CHAPTER II THE CAPTIVITY AND ESCAPE OF PATRICK § 1. _Parentage and Capture_ The conversion of Ireland to Christianity has, as we have seen, its modest place among those manifold changes by which a new Europe was being formed in the fifth century. The beginnings of the work had been noiseless and dateless, due to the play of accident and the obscure zeal of nameless pioneers; but it was organised and established, so that it could never be undone, mainly by the efforts of one man, a Roman citizen of Britain, who devoted his life to the task.
