HE was born in the country of Hy-Conalls, in Ireland, in the latter part
of the fifth century, was a disciple of the abbots Cassidus and Natal,
or Naal: then travelled for spiritual improvement to Rome, and thence
into Britain. In this kingdom he contracted a close friendship with St.
David. After his return he founded many churches in Ireland, and a great
monastery in Inis-Cathaig, an island lying at the mouth of the river
Shannon, which he governed, and in which he continued to reside after he
was advanced to the episcopal dignity. The abbots, his successors for
several centuries, were all bishops, till this great diocese was divided
into three, namely, of Limerick, Killaloe, and Ardfert. St. Senan died
on the same day and year with St. David; but was honored in the Irish
church on the 8th of March. A town in Cornwall bears the name of St.
Senan. See his acts in Colgan, p. 602.
