There was in addition Irish settlement in south-western Wales, the modern Dyfed, then known as Demetia, from perhaps as early as the fourth century. The evidence for this comes from three different types of source. There are memorial stones in the area inscribed with Irish names, often in the linear script known as ogham, which seems to have originated in the south-east of Ireland at about this period. There are place-names with Irish elements, hard to date, whose distribution to a great degree overlaps with the inscribed stones. And there are legends, which may contain a kernel of historical truth, about the fourth-century migration of a tribe called the Déisi from south-eastern Ireland to Wales. It is by means of these settlers, presumed to have maintained contact with their kinsfolk in Ireland, that elements of Romano-British culture are most likely to have seeped back there. One such element was language, the borrowing of a number of Latin loanwords into Old Irish. Another was religion: the Irish settlers were near neighbours of Caerleon-on-Usk with its Diocletianic martyrs Aaron and Julius, and its Christian landed gentry in the villas of Gwent and Glamorgan. It was probably from south Wales that Christianity first came to Ireland.
It was to these Irish Christians that Palladius was sent in 431. Who was he? A person of the same name is mentioned in an earlier annal in Prosper’s chronicle, that for 429, which runs as follows: ‘Agricola, a Pelagian, the son of the Pelagian Bishop Severianus, corrupts the churches of Britain by the insinuation of his teaching. However, at the suggestion of the Deacon Palladius, Pope Celestine sends Bishop Germanus of Auxerre as his legate and he guides the Britons back to the Catholic faith after routing the heretics.’ The mission of Bishop Germanus to Britain in 429, and another one a few years later (perhaps 435/6), are attested in other sources. It is plain moreover from remarks made by Prosper in another of his works that there was anxiety that the taint of heresy might infect the Irish Christian community too.
Now the name Palladius was not particularly common in the western provinces of the empire. It is almost inconceivable that there were two different men called Palladius who both concerned themselves with the spiritual welfare of the Christian communities of the British Isles in the second quarter of the fifth century. We assume that there was a single Palladius, and we further assume that he held the office of deacon in one of the churches of northern Gaul, probably but not necessarily Auxerre, from which he was despatched to Rome in 429. That is all we know of Palladius. We do not know where the seat of his bishopric was, though we may suspect that it was in the south-east quarter of the island. We do not know how long his episcopate lasted, nor the names and doings of his successors (if any). But there he stands: the first known figure in the history of organized Irish Christianity. It is his misfortune to have been overshadowed by the next: Patrick.
Patrick is a famously difficult subject for the historian. It might be easiest to start by indicating some of the things which he did not do. He did not expel snakes from Ireland: the snakelessness of Ireland had been noted by the Roman geographer Solinus in the third century. He did not compose that wonderful hymn known as ‘Saint Patrick’s Breastplate’: its language postdates him by about three centuries. He did not drive a chariot three times over his sister Lupait to punish her unchastity: the allegation that he did first occurs in a life of Patrick which is a farrago of legend put together about 400 years after his death. He did not use the leaves of the shamrock to illustrate the Persons of the Trinity for his converts: true, he might have done; but it is not until the seventeenth century that we are told that he did.
It would be possible to list many more things that Patrick did not do. Enough has been said to indicate that we are dealing with a figure whose reality has to a great degree been obscured by the accretion of later legend – and, one might add, of later controversy, whether sectarian or nationalistic. It cannot be too strongly urged that in studying Patrick it is absolutely essential to focus attention upon the earliest texts only: all others are suspect because their authors had axes to grind of one sort or another – the primacy of the church of Armagh, the ultra-Catholic character of Patrick, the ultra-Protestant character of Patrick, the claim that there were two Patricks, the claim that there was no Patrick because he was Palladius, and so forth. The earliest texts are two, both of them securely attributed – despite some doubts by hyper-critical scholars – to Patrick himself. In chronological order of composition they are the Epistola (or ‘Letter’) and the Confessio (or ‘Declaration’). The Epistola is a letter addressed to the troops serving under the command of a certain Coroticus, denouncing them for the massacre of some of Patrick’s converts. The Confessio is a justification of his career and conduct, apparently in answer to critics or accusers. Both works contain autobiographical materials of which Patrician scholars have wrestled to make sense.5
The wrestling is necessary because Patrick’s writings are exceedingly difficult to interpret. This is partly because the texts might have been garbled in transmission, but above all it is owing to the language in which they are written. Patrick wrote in Latin, but of a very peculiar kind; indeed, his Latin is unique in the whole vast corpus of ancient or early Christian Latin literature. He had received little formal education – it was to cause him shame all his life – and he did not handle the Latin language with any facility. He longs, passionately longs, to make himself clear to his readers but has the utmost difficulty in so doing. His Latin is simple, awkward, laborious, sometimes ambiguous, occasionally unintelligible. It follows that there is a large latitude for debate about what his words actually mean, a latitude of which Patrician scholars have shown no bashfulness in liberally availing themselves.
All that is necessary here is to furnish a concise indication of what is generally agreed, except on the lunatic fringes of Patrician studies, about Patrick’s career. I deliberately refrain from entering into questions of chronology, which present the thorniest of all problems for those in quest of the historical Patrick. It is accepted that his adult life fell within the fifth century. His episcopate in Ireland must postdate 431 because Prosper tells us that Palladius was Ireland’s first bishop. Beyond that we need not go.
Patrick tells us in the Confessio that he was of British and landed birth. His family owned an estate at an unidentified place called Bannaventa. They were not only Christians but ecclesiastics: Patrick’s grandfather Potitus was a priest and his father Calpornius a deacon.* Patrick was brought up a Christian but on his own admission was not a good one during his childhood. When he was nearly sixteen he was taken captive by Irish raiders and carried off into slavery in Ireland. For six years he worked as a herdsman at a place which he refers to as ‘the forest of Foclut which is near the western sea’ (tentatively identified as the region of Killala in County Mayo). It was during this period of slavery that his Christian faith deepened. At the end of six years he managed to escape, and after much danger and hardship found himself in Gaul, where he appears to have spent some time. Then he returned to Britain and rejoined his family. It was at home that he had the most important of all the dreams through which, as he believed, God guided his life: he experienced a call to undertake the conversion of the pagan Irish to Christianity. After (presumed) preparation he was consecrated a bishop and returned to Ireland. Although this has to be inferred, the likelihood is that the zone of his missionary labours was the northern half of the island. He spent the rest of his life in Ireland, despite perils and privations making converts and establishing a church. He also had to face accusations and misrepresentations about the conduct of his mission, to which the Confessio seems to have been the reply.
Patrick recalled his vocation in a well-known passage which yet can bear repetition because it is such an extraordinary piece of writing. It occurs in Chapters 23 to 25 of the Confessio.
