Did you know that Saint Patrick is the patron saint of engineers (as well as of Ireland, St. Brigid, St. Columba, Nigeria, and outcasts)? Although everyone is familiar with the tale of Saint Patrick driving the snakes from Ireland, he is also credited with fostering the development of arts and crafts and introducing the knowledge of the use of lime as mortar in Ireland. He is responsible for the initial construction of clay churches in Ireland in the fifth century. Another of St. Patrick’s achievements was teaching the Irish to build arches of lime mortar instead of dry masonry. These beginnings of ceramic work developed into organized crafts, and that is how St. Patrick became a patron saint of engineers.
