Sillan of Bangor

Saint Sillan of Bangor (Sillian, Silvan, in Latin Selanus, in Irish Síoláin), a holy monk, was an Irish saint and abbot who died in 608 or 610, abbot of the monastery of Bangor in County Down. He was a disciple of Saint Comgall, the founder and first abbot of Bangor, and his second or third successor; according to one source he led the monastery from 602. He is called "master" in the sources, which perhaps shows that he was learned in Latin scholarship.

His name appears in the Annals of Tigernach, as Sillán moccu Cumaine, dying in 608, and in the Annals of Ulster, as Sillán moccu Minn, dying in 610. The village of Kilsheelan in County Tipperary bears his name. He is commemorated on 28 February, by the Western calendar (new style). He is honored as a saint of the undivided Church.
