Saint David was a 6th-century Welsh prelate who served as the Bishop of Mynyw. Born in Pembrokeshire, he became a renowned teacher and preacher, establishing monastic communities throughout Wales, Brittany, and Dumnonia. He is celebrated as the patron saint of Wales and is remembered for his ascetic lifestyle and his role in opposing Pelagianism. His influence extended to the founding of churches, including a connection to Glastonbury Abbey, and he is traditionally associated with the leek, a symbol of his nation.
