Saint Sulian may be identical with the Breton Saint Sulien of Cornouaille and Domon�e.
He was the founder and abbot, but not the patron, of Luxulyan in Cornwall. There is considerable, but understandable, confusion between Sulian and another Saint Sulinus of East Brittany and the Welsh Saint Tysilio (Suliau). There appears to be three separate saints (Farmer).
Troparion of St Sulian Tone 5O
fervent St Sulian,/ thou didst persevere, overcoming all obstacles,/ and thy life as a monk was radiant./ Thou didst work miracles/ when living in thy monastery,/ and wonders shone forth from thy tomb./ We praise thee, holy Abbot Sulian.
