They built round towers for their protection and introduced a study of Hebrew and Greek in the monastic settlement. Oengus gives lists of bishops and pilgrims who lived in groups of seven. The oldest copy of his work, about 1200, is in the Franciscan Convent on Merchant's Quay, Dublin. In addition he wrote The Martyrology of Tallaght and Saltair na Rann, a poem on OT history.
