Very many of our ancient authorities mention this visit to Lerins, or some other of the rocky islets that abound in that part of the Mediterranean, and several of which were then inhabited by holy men. It is said expressly in the Hymn of St. Fiacc, the oldest of St. Patrick's lives, that he studied the canons with Germanus, that the angel sent him across the Alps, and that he stayed in the islands of the Tyrrhene Sea. It is not easy to fix the date of this visit nor its duration; it is, however, in itself extremely probable, independently of the high authority of Fiacc's Metrical Life as well as of the Third Life, and Probus' Fifth Life. The Third Life represents our saint as spending several years in an island called Tamerencis, or, as Probus puts it, with the barefooted hermits in a certain island of the sea. This island in all probability was Lerins, and the barefooted hermits were the monks of St. Honoratus, who was thus the third teacher of St. Patrick. When Honoratus, flying fame and friends, came to Lerins in A.D. 410, it was covered with dense shrubberies, through whose tangled masses innumerable serpents glided and scared away the fishermen, who chanced to land on the barren and inhospitable rock. But Honoratus was not to be daunted. With a few faithful companions he set to work, and soon cleared a space for their cells, and for such patches of agriculture, as would supply their scanty needs. The monks were patient and laborious; the soil was naturally not ungrateful. The serpents were banished, the brakes were all cut down, and fruit trees planted in their stead. There was a bright sky above, and glittering seas around; snow-capped mountains arose in the blue distance; orange groves wafted their delicious fragrance over the waters so that Lerins became an Eden, where the sights of nature were as fair, and the hearts of the men as pure, as they were in Paradise. There, too, St. Honoratus, afterwards raised in A.D. 429 to the See of Arles, founded a famous school which was long celebrated in the south of Europe, and produced some of the most distinguished scholars of the fifth century. Such were their piety and learning that all the cities round about strove emulously to have monks from Lerins for their bishops.
