Rome, once the proud and ruthless “mistress of the world,” has lost for ever her ancient sway. No longer does the wide world stand in awe of her. But on the ruins of her lost dominion a new, a merciful, and a blessed power is springing up. She has become the centre of the Christian religion, and ere long she stretches out her missionary arms to the isles of the west. St. Patrick is commissioned as the ambassador of God to convert the Scots in Ireland to the new faith. Devoted men in skin-clad boats of wicker-work cross the channel from the Emerald Isle to carry the good news to the natives of south-west Scotland. Amongst them is the great Columba of Donegal, prince in the eyes of his fellows, but in his own a meek bondsman of Christ. With his twelve companions he steers for the rising sun, and his barks run ashore on the little bare island of Iona, where he lands and builds his wattled church and the rude huts of his infant monastery. From this retreat, which has become one of the most sacred spots on earth, Columba’s friends go fearlessly through the land into the wildest glens and the remotest clachans, preaching the gospel, and slowly and surely winning the Picts and Scots to Christianity. But England is still in her pagan darkness; she knows nothing except by vague rumour of the new faith which is slowly transforming the world. The English still worship their fierce old deities; still swear by oak, thorn, and ash; still look to Valhalla as the meed of the warrior who dies in hard-fought battle. Men of kindred blood still struggle for mastery under their kings, and the vanquished are still found in the slave-markets of the Continent. It is the sight of English lads exposed for sale in Rome which touches the heart of a young deacon, and stirs him to cherish the conversion of these islanders as the great ideal of his life. He sees the white limbs, the fair faces, the blue eyes, and the yellow hair of the lads, and asks the merchant whence they come. “From Britain,” is the answer. “Are they Christians or pagans?” is his next question; and when he learns that they are pagans, he sighs heavily and exclaims, “Ah! grief of griefs that the prince of darkness should lay claim to beings of such fair form; that there should be so much grace in the countenance, yet none in the soul.”
