Blane was well respected and revered, as is evidenced by the number of places honoring him, such as Dunblane, Kilblane, and Strathblane. The church which Blane founded in Kingarth, on the Isle of Bute, holds his remains, but the center of his cult is in Dunblane, on the mainland, where a bell from his monastery is kept. Most of the information we have about Blane comes from the Aberdeen Breviary, which was published in 1510 at the behest of King James IV of Scotland, who wanted a Scottish counterpart to the English Sarum Breviary.
Blane died around A.D. 590, and his feast day is August 11th.
