Columba in the busy years that elapsed between 546 and his final departure from Ireland in 563, looked upon Derry as his home. It was his first and dearest monastery. It was in his own Tyrconnell, but a few miles from that home by Lough Gartan, where he first saw the light, and from his foster home amid the mountains of Kilmacrenan, that, rising with their green belts of trees and purple mantles of heather over the valleys, seemed like huge festoons hung from the blue-patched horizon. Then the very air was redolent of sanctity. If he turned to the south, the warm breezes that swayed his cowl reminded him that away behind those wooded hills in Ardstraw, prayed Eugene, destined to share with him the patronage of the diocese, and that farther up, St. Creggan, whose name the Presbyterian farmers unconsciously preserve in the designation of their townland, Magheracreggan, presided over Scarrabern, the daughter-house of Ardstraw. Then turning slowly northwards he would meet with the persons, or relics, of St. O'Heney in Banagher, St. Sura in Maghera, St. Martin in Desertmartin, St. Canice in Limavady, St. Goar in Aghadoey, St. Cardens in Coleraine, St. Frigidian in Moville, St. Comgell in Culdaff, St. McCartin in Donagh, St. Egneach in the wildly beautiful pass of Mamore, St. Mura in Fahan, and his own old teacher, St. Cruithnecan in Kilmacrenan. All these, and many others, whose names tradition but feebly echoes, were contemporary, or nearly so, with him; and with many of them, he was united in the warmest bonds of friendship,--a friendship that served to rivet him the more to Derry. Even the budding glories of Durrow and Kells could not draw him away from his "loved oak-grove;" and at length, when the time had come for him to go forth and plant the faith in a foreign land, it was the monks of Derry who received his last embrace ere he seated himself with his twelve companions, also monks of Derry, in his little osier coracle, and with tearful eyes watched his grove till the topmost leaf had sunk beneath the curving wave. When twenty-seven years after he visited his native land, as the deputy of an infant nation and the saviour of the bards, on whom, but for his kindly intercession, the hand of infuriated justice had heavily fallen, his first visit was to Derry. It was probably during this visit that he founded that church on the other side of the Foyle, whose ivy-clad walls and gravelled area the reader of "Thackeray's Sketch Book" may remember; but few know that it was wantonly demolished by Dr. Weston (1467-1484), the only Englishman who ever held the See of Derry; and "who," adds Colgan, "began out of the ruins to build a palace for himself, which the avenging hand of God did not allow him to complete."
