Of this abbot nothing certain is known. Colgan attempted to identify him with S. Isserninus, the companion of S. Patrick. According to Albert le Grand, S. Sezin was born in Ulster, in 402, studied at Rome, became a bishop in Ireland, and passed into Brittany in 477, where he died as late as 529, having lived 127 years. But the lections in the Breviary of S. Pol de Léon, from which Albert le Grand made up this history, are for the most part taken word for word from the Life of S. Kieran. We may allow that the saint was an Irishman, and that he died at Guic-Sezni, in the beginning of the 6th century, but that is all we can say of him. S. FRIDOLIN, AB. OF SICKINGEN. (END OF 7TH CENT.) [Molanus and Greven in their additions to Usuardus. Canisius in his German Martyrology. Anglican and later Irish and Scottish Martyrologies. The Acts of Fridolin were preserved in a monastery on the Moselle, where they were found, and recast in a more ornate style, by a monk, Balther, in the beginning of the 12th cent. The story of this is rather curious. In the monastery of Sickingen there was no copy of the life of S. Fridolin, on account of the monastery having been destroyed by the Huns about 938. But Balther, a monk of Sickingen, happening to visit a monastery on the Moselle, which had been founded by S. Fridolin, found the life there. He asked for it, but the prior refused to give it him, so he learned it by heart, as well as he could, "partly carrying it away word for word, and partly gathering the subject-matter," after which he set to work and re-wrote it, incorporating the portions he knew by heart with that portion which he wrote in his own words. He says that he was puzzled to find that in the MS. the saint was called Fridhold, whereas at Sickingen they were wont to call him Fridolin. Fridhold was undoubtedly the ancient and most correct form of the name, and Fridolin is a diminutive.]
