St. Patrick and the early Christians of the fifth century spent much of their time and labour in the conversion of pagans and the building of churches. Columcille and the leading churchmen of the sixth century, on the other hand, gave themselves up more to the foundation of monastic institutions and the conduct of schools. They belonged to what is well known in Irish ecclesiastical history as the second Order of Saints. The first Order was composed of Patrick and his associates, bishops filled with piety, founders of churches, three hundred and fifty in number, mostly Franks, Romans, and Britons, but with some Scots [i.e. Irish] also amongst them. These worshipped, says the ancient "Catalogue of the Saints," one head—Christ, and followed one leader—Patrick. They had one tonsure, one celebration of the Mass, and one Easter. They mixed freely in the society of women, because they feared not the wind of temptation, and this first Order of Saints, as it is called, is reckoned by the Irish to have lasted during four reigns.

The next Order of Saints had few bishops but many priests, this was the order to which Columcille belonged, and most of the saints who founded the great schools of Ireland which in the following century became so flourishing and spread their fame throughout Europe, as those of Ciaran and Finnian and Brendan, and a score of others. This Order shunned all association with women, and would not have them in their monasteries.[1] These saints whilst worshipping God as their head, and celebrating one Easter and having one tonsure, yet had different rites for celebrating, and different rules for living. The rite with which they celebrated Mass they are said to have secured from the British saints, St. David, St. Gildas, and others. They also lasted for four reigns, or, roughly speaking, during the last three quarters of the sixth century.

After these came what is called the third Order of Saints who appear in their time to have been pre-eminent amongst the other Christians, and to have been mostly anchorites, who lived on herbs and supported themselves by such alms as they were given, despising all things earthly and all things fleshly. They observed Easter differently, they had different tonsures, they had different rules of life, and different rites for celebrating Mass. They are said to have numbered about a hundred and to have lasted down to the time of the great plague in 664.

This third Order, says the writer of the "Catalogue of Saints," who gives their names, was holy, the second holier, but the first Order was most holy. "The first glowed like the sun in the fervour of their charity, the second cast a pale radiance like the moon, the third shone like the aurora. These three Orders the blessed Patrick foreknew, enlightened by heavenly wisdom, when in prophetic vision he saw at first all Ireland ablaze, and afterwards only the mountains on fire, and at last saw lamps lit in the valleys."

By the middle of the sixth century Ireland had been honeycombed from shore to shore with schools, monasteries, colleges, and foundations of all kinds belonging to the Christian community, and books had multiplied to a marvellous extent. At the same time the professional bards flourished in such numbers that Keating says that "nearly a third of the men of Ireland belonged, about that period, to the poetic order." Omitting for the present the consideration of the bards and the non-Christian literature of poem and saga—mostly anonymous—which they produced, we must, take a rapid survey of some of the most important of the Christian schools, whose pious professors, whose number, and whose learning, secured for Ireland the title of the Island of Saints. We have already seen how the three patron saints of Ireland established their schools in Armagh, Kildare, and Iona, and their example was followed by hundreds.

St. Enda, the son of a king of Oriel, after having studied at some school in Great Britain (probably with St. Ninian—who is said to have been himself an Irishman—at his noble monastery of Candida Casa in Galloway, built about the year 400), and after travelling through various parts of Ireland, settled down finally about the year 483 in the rocky and inaccessible island of Aran Mór, and was the first of those holy men who have won for it the appellation of Aran of the Saints. "One hundred and twenty-seven saints sleep in the little square yard around Killeany Church"[2] alone, and we are told that the countless numbers of saints who have mingled their clay with the holy soil of Aran will never be known until the day of Judgment. Here most of the saints of the second Order repaired sooner or later, to be instructed by, or to hold converse with St. Enda; amongst them Brendan the Voyager, whose wanderings, under the title of Navigatio Brendani, became so well known in later ages to all mediæval Europe. To him also came St. Finnian of Clonard, who was himself celebrated in later days as the "Tutor of the Saints of Erin." From the remote north came Finnian of Moville, Columcille's first teacher, and Ciaran, the carpenter's son, the illustrious founder of Clonmacnois. St. Jarlath of Tuam was there too, with St. Carthach the elder, of Lismore, and with St. Keevin of Glendalough. St. Columcille[3] himself was amongst Enda's visitors, and tore himself away with the utmost difficulty, solacing himself by recourse to the Irish muse as was his wont—

"Farewell from me to Ara's Isle,
Her smile is at my heart no more,
No more to me the boon is given
With hosts of heaven to walk her shore.
How far, alas! how far, alas!
Have I to pass from Ara's view,
To mix with men from Mona's fen,
With men from Alba's mountains blue.
Bright orb of Ara, Ara's sun,
Ah! softly run through Ara's sky,
To rest beneath thy beam were sweeter
Than lie where Paul and Peter lie.
O Ara, darling of the West,
Ne'er be he blest who loves not thee,
O God, cut short her foeman's breath,
Let Hell and Death his portion be.
O Ara, darling of the West,
Ne'er be he blest who loves not thee,
Herdless and childless may he go
In endless woe his doom is dree.
O Ara, darling of the West,
Ne'er be he blest who loves thee not,
When angels wing from heaven on high
And leave the sky for this dear spot."[4]

Another early school was that founded by St. Finnian at Cluain Eraird, better known under its corrupt form Clonard, a spot hard by the river Boyne, to which students from both north and south resorted in great numbers. Finnian, who was of the Clanna Rury, or Irian race, had been baptized by Bishop Fortchern, who—so quickly did the Christian cause progress—was a grandson of King Laeghaire, who withstood St. Patrick. This Fortchern, too, like Brigit's favourite bishop, was a skilled artificer in bronze and metal, a calling to which many of the early saints evinced a strong bias. Clonard even during Finnian's lifetime became a great school, and three thousand students are said to have been gathered round it, amongst them the so-called Twelve Apostles of Erin. These are Ciaran of Clonmacnois and Ciaran of Saigher, who is patron saint of Ossory; Brendan of Birr, the "prophet," and Brendan of Clonfert, the "navigator"; Columba of Tir-da-glass and Columcille; Mobhí of Glasnevin and—infaustum nomen!—Rodan of Lothra or Lorrha; Senanus of Iniscathy, whose name is known to the lovers of the poet Moore; Ninnidh of Loch Erne; Lasserian, and St. Cainnech of Kilkenny, known in Scotland as Kenneth, and second in that country only to St. Columcille and St. Brigit in popularity. The school of Clonard was founded about the year 520, when, to quote the rather jingling hymn from St. Finnian's office—

"Reversus in Clonardiam
Ad cathedram lecturæ
Opponit diligentiam
Ad studium scripturæ."
