St. Gundleus was the eldest son to the king of the Dimetians in South-Wales. After the death of his father, though the eldest son, he divided the kingdom with his six brothers who nevertheless respected and obeyed him as if he had been their sovereign. He married Gladusa and was father of St. Canoc and St. Keyna. He retired wholly from the world long before his death and passed his time in a solitary little dwelling near a church which he had built. His clothing was sackcloth, his food barley-bread, which was usually covered with ashes and his drink was water. Prayer and contemplation were his constant occupation to which he rose at midnight, and he subsisted by the labor of his hands for many years. He departed to our Lord towards the end of the fifth century and was glorified by miracles.
