It appears, however, that he was no disciple of S. Patrick at all, and did not live in his times. His name does not occur in Tirechan's list, nor in any of the Lives of S. Patrick, except in those two just quoted, and his appearance in them is evidently due to the legends in circulation concerning the meeting. Had S. Kieran been a disciple of the apostle, how could he have become a scholar of S. Finnian of Clonard, in the 6th century? For such he is stated to have been, not only in the Life of S. Finnian, and in that of his illustrious namesake of Clonmacnois, but also in the tract which is called his first life, and which enters into more particulars than the other. S. Finnian's school could not have become celebrated before 534. In both Kieran's lives his namesake of Clonmacnois, who died in 549, and the two Brendans, one of whom died in 577, and the other a few years earlier, are spoken of as having had transactions with him. We may then safely conclude that he belonged to the sixth century, became distinguished towards the middle of it, and died during its latter half. As this was known to be the case, his blundering biographers strove to reconcile their nonsense concerning the antiquity and privileges of Saigir, with the true date of his death, by making him die at the age of about 300 years, although, had they calculated better, about 220 years might have sufficed. Kieran, we may safely conclude, was made a bishop about the year 538. Having retired to a lonesome spot, since called Saigir, he led at first the life of a hermit, and after some time erected a monastery, around which a city gradually grew up. Next he established a nunnery in the neighbourhood for his mother Liadania, and some pious virgins, her companions, whence the church Killiadhuin got its name. Besides the care of his monastery, Kieran was assiduously employed in preaching the Gospel in Ossory, and he converted a great number of heathen. He is usually considered to have been the first bishop of Ossory, and founder of that see. It is singular that, notwithstanding all that is said in the lives, in praise of Kieran, he is not much spoken of in the accounts of contemporary saints, and that none of the Irish annals or hagiologies give the date of his death. Hence Colgan was inclined to think that he died in Cornwall, and is to be identified with S. Piran, of Peranzabulo. But the first life hints that he died at Saigir. Although the year of his death is unknown, there can be little doubt of his having been alive after the year 550.
