- Ségéne mac Fiachnaí
Ségéne mac Fiachnaí, or Ségéne of Iona, (died
12 August ,652 ) was the fifthabbot ofIona (623-652).Ségéne was of the
Cenél Conaill , the same kindred asColumba , and he was the nephew of a previous abbot, Lasrén. It was during Ségéne's long abbacy that the famous controversy regarding the dating ofEaster first made itself properly felt. Ségéne is known to have vigorously defended the Gaelic dating, and put his name to a letter written by the Gaelic clergy toPope Severinus in 638.Ségéne also established the first Gaelic missionaries amongst the English, sending Corman and then Áedan, the latter of whom, with the help of King
Oswald of Northumbria (who himself had spent time in exile at Iona), established a daughter house and bishopric atLindisfarne . It is not known if Ségéne ever met Columba, but he was a vital collector/transmitter of stories about the saint.He died on
12 August ,652 .Bibliography
