From Robert Chambers, The Book of Days, 1869:

LEGENDARY HISTORY OF ST. PATRICK

Almost as many countries arrogate the honour of having been the natal soil of St. Patrick, as made a similar claim with respect to Homer. Scotland, England, France, and Wales, each furnish their respective pretensions: but, whatever doubts may obscure his birthplace, all agree in stating that, as his name implies, he was of a patrician family. He was born about the year 372, and when only sixteen years of age, was carried off by pirates, who sold him into slavery in Ireland; where his master employed him as a swineherd on the well-known mountain of Sleamish, in the county of Antrim. Here he passed seven years, during which time he acquired a knowledge of the Irish language, and made himself acquainted with the manners, habits, and customs of the people. Escaping from captivity, and, after many adventures, reaching the Continent, he was successively ordained deacon, priest, and bishop: and then once more, with the authority of Pope Celestine, he returned to Ireland to preach the Gospel to its then heathen inhabitants.

The principal enemies that St. Patrick found to the introduction of Christianity into Ireland, were the Druidical priests of the more ancient faith, who, as might naturally be supposed, were exceedingly adverse to any innovation. These Druids, being great magicians, would have been formidable antagonists to any one of less miraculous and saintly powers than Patrick. Their obstinate antagonism was so great, that, in spite of his benevolent disposition, he was compelled to curse their fertile lands, so that they became dreary bogs: to curse their rivers, so that they produced no fish: to curse their very kettles, so that with no amount of fire and patience could they ever be made to boil; and, as a last resort, to curse the Druids themselves, so that the earth opened and swallowed them up. …

The greatest of St. Patrick’s miracles was that of driving the venomous reptiles out of Ireland, and rendering the Irish soil, for ever after, so obnoxious to the serpent race, that they instantaneously die on touching it. Colgan seriously relates that St. Patrick accomplished this feat by beating a drum, which he struck with such fervour that he knocked a hole in it, thereby endangering the success of the miracle. But an angel appearing mended the drum: and the patched instrument was long exhibited as a holy relic. …

When baptizing an Irish chieftain, the venerable saint leaned heavily on his crozier, the steel-spiked point of which he had unwittingly placed on the great toe of the converted heathen. The pious chief, in his ignorance of Christian rites, believing this to be an essential part of the ceremony, bore the pain without flinching or murmur; though the blood flowed so freely from the wound, that the Irish named the place St. fhuil (stream of blood), now pronounced Struill, the name of a well-known place near Downpatrick. And here we are reminded of a very remarkable fact in connection with geographical appellations, that the footsteps of St. Patrick can be traced, almost from his cradle to his grave, by the names of places called after him.

Thus, assuming his Scottish origin, he was born at Kilpatrick (the cell or church of Patrick), in Dumbartonshire. He resided for some time at Dalpatrick (the district or division of Patrick), in Lanarkshire; and visited Crag-phadrig (the rock of Patrick), near Inverness. He founded two churches, Kirkpatrick at Irongray, in Kireudbright; and Kirkpatrick at Fleming, in Dumfries: and ultimately sailed from Portpatrick, leaving behind him such an odour of sanctity, that among the most distinguished families of the Scottish aristocracy, Patrick has been a favourite name down to the present day.

Arriving in England, he preached in Patterdale (Patrick’s dale), in Westmoreland: and founded the church of Kirkpatrick, in Durham. Visiting Wales, he walked over Sarn-badrig (Patrick’s causeway), which, now covered by the sea, forms a dangerous shoal in Carnarvon Bay: and departing for the Continent, sailed from Llan-badrig (the church of Patrick), in the island of Anglesea. Undertaking his mission to convert the Irish, he first landed at Innis-patrick (the island of Patrick), and next at Holmpatrick, on the opposite shore of the mainland, in the county of Dublin. Sailing northwards, he touched at the Isle of Man, sometimes since, also, called. Innis-patrick, where he founded another church of Kirkpatrick, near the town of Peel. Again landing on the coast of Ireland, in the county of Down, he converted and baptized the chieftain Dichu, on his own threshing-floor. The name of the parish of Saul, derived from Sabbal-patrick (the barn of Patrick), perpetuates the event. He then proceeded to Temple-patrick, in Antrim, and from thence to a lofty mountain in Mayo, ever since called Croagh-patrick.

He founded an abbey in East Meath, called Domnach-Padraig (the house of Patrick), and built a church in Dublin on the spot where St. Patrick’s Cathedral now stands. In an island of Lough Deng, in the county of Donegal, there is St. Patrick’s Purgatory: in Leinster, St. Patrick’s Wood; at Cashel, St. Patrick’s Rock; the St. Patrick’s Wells, at which the holy man is said to have quenched his thirst, may be counted by dozens. He is commonly stated to have died at Saul on the 17th of March 493, in the one hundred and twenty-first year of his age. …

The shamrock, or small white clover (trifolium repens of botanists), is almost universally worn in the hat over all Ireland, on St. Patrick’s day. The popular notion is, that when St. Patrick was preaching the doctrine of the Trinity to the pagan Irish, he used this plant, bearing three leaves upon one stem, as a symbol or illustration of the great mystery. To suppose, as some absurdly hold, that he used it as an argument, would be derogatory to the saint’s high reputation for orthodoxy and good sense: but it is certainly a curious coincidence, if nothing more, that the trefoil in Arabic is called skamrakh, and was held sacred in Iran as emblematical of the Persian Triads. Pliny, too, in his Natural History, says that serpents are never seen upon trefoil, and it prevails against the stings of snakes and scorpions. This, considering St. Patrick’s connexion with snakes, is really remarkable, and we may reasonably imagine that, previous to his arrival, the Irish had ascribed mystical virtues to the trefoil or shamrock, and on hearing of the Trinity for the first time, they fancied some peculiar fitness in their already sacred plant to shadow forth the newly revealed and mysterious doctrine. …

In the Galtee or Gaultie Mountains, situated between the counties of Cork and Tipperary, there are seven lakes, in one of which, called Lough Dilveen, it is said Saint Patrick, when banishing the snakes and toads from Ireland, chained a monster serpent, telling him to remain there till Monday.

The serpent every Monday morning calls out in Irish, ‘It is a long Monday, Patrick.’

That St Patrick chained the serpent in Lough Dilveen, and that the serpent calls out to him every Monday morning, is firmly believed by the lower orders who live in the neighbourhood of the Lough.
