Sulien
From Wikipedia, the free encyclopedia
Sulien, an eleventh century cleric was abbot/bishop of St. David's for two periods (1071-1076 and1079-1090). He died in the following year. He is closely associated with the clas church at Llanbadarn Fawr near Aberystwyth where it appears that he took refuge as St. David's was at times exposed to Viking incursions. Llanbadarn enjoyed a reputation for scholarship. One of his sons, Rhigyfarch or Ricemarch is the author of a Life of St. David.
