Tysul

Saint Tysul (Tysul ap Corun ap Cunedda) was a Welsh saint of the 6th century, patron of the churches of Llandysul in Ceredigion and Llandyssil in Montgomeryshire (Powys). He is believed to have been born around 462 and to have reposed in 554.

According to tradition he was the son of Corun, son of Ceredig (who gave his name to the kingdom of Ceredigion), and a cousin of Saint David. He built a church at Llandyssil in Powys, on a hillside south-⁠east of the village; only the south porch survives, the rest having been replaced in 1866 by a new church. The old church was renowned for its timber belfry, and its demolition met with opposition. At Llandysul in Ceredigion there is a church of the 13th century. His day is 31 January, and by tradition also 3 February, by the Western calendar (new style). He is honored as a saint of the undivided Church.
