Who was St David of Wales
David of Wales (ca. 512-587), known in Welsh as Dewi Sant, was a 6th century bishop and monastic founder in Wales and is its patron saint. He is also known as the Dewi Ddyfrwr (David the Water Drinker) due to his drinking only water and the founding of many holy wells associated with his life. His feast day in the Church is March 1.
David was born on a stormy night at or near Capel Non (Non's chapel) within a short walk of the present day city of Saint David's. The ruins of the medieval chapel are visible near the site, and a nearby well is still a site of pilgrimage. He was baptised by the Irish monk St. Elvis, and educated at the monastery of Hen Fynyw. After ordination, David was taught by the elderly monk Paulinus, whose blindness the young David healed by making the sign of the cross over the monk's eyelids.
He became renowned as a teacher and preacher, founding monasteries in Britain and Brittany (on the west coast of modern France), in a period when neighbouring tribal regions (that were to be united as England three hundred years later) were still mostly pagan. He rose to a bishopric, and presided over two synods, as well as going on pilgrimages to Jerusalem where he was anointed as a bishop by the patriarch.
