Dewi Sant (St David)
According to the legend, Dewi was the son of Non, the daughter of Gynyr and Sandde (or Sant), the King of Ceredigion. Non became a nun soon after the birth and went to Brittany to live. According to one story, Sandde was the nephew of King Arthur.
After being taught by Peulyn, Dewi decided to live a simple life eating only bread and water. He became known as Aquaticus (the Water Man) because of this. He set about establishing a monastery near what is now St David’s.
Peulyn’s Sight
Peulyn was Dewi’s teacher. He suffered from terrible headaches and one morning he woke to find that he was completely blind. He heard a Voice telling him that his sight would be restored by one of his own pupils. Samson and Gildas both tried without success. Then Dewi touched the old teacher’s eyes and his sight came back immediately. According to legend the miracle happened on Mynydd Llanllyfni near Caernarfon.
