DISTANT ISLANDS: But Irish monks were mariners as well as apostles. Their hide-covered currachs were often launched in the hope of discovering solitudes in the ocean. Adamnan records that Baitan set out with others in search of a desert in the sea. St. Cormac sought a similar retreat and arrived at the Orkneys. St. Molaise's holy isle guards Lamlash Bay, off Arran. The island retreats of the Bass, Inchkeith, May, and Inchcolm, in the Firth of Forth, are associated with the Irish saints Baldred, Adamnan, Adrian, and Columcille. St. Maccaldus, a native of Down, became bishop of the Isle of Man. Remarkable, too, is the fact that Irish monks sailed by way of the Faroe Islands to distant Iceland. These sailor-clerics, who settled on the southeast of the island, were spoken of by later Norwegians as "papar." After their departure--they were probably driven away by Norwegian pagans--these Icelandic apostles "left behind them Irish books, bells, and croziers, wherefrom one could understand they were Irishmen." But St. Brendan, the voyager, is the most wonderful of the mariner monks of Ireland. He accomplished apostolic work in both Wales and Scotland, but his seafaring instincts urged him to make missionary voyages to regions hitherto unknown. Some writers, not without reason, have actually maintained that he and his followers traveled as far as the American shore. Be this as it may, the tradition of the discoveries of this Irish monk kept in mind the possibly existing western land, and issued at last in the discovery of the great continent of America by Columbus.
