The earliest works of literature produced in Ireland are by Saint Patrick; his "Confessio" and "Epistola", both in Latin. The earliest literature in Irish consisted of original lyric poetry and prose sagas set in the distant past. The earliest poetry, composed in the 6th century, illustrates a vivid religious faith or describes the world of nature, and was sometimes written in the margins of illuminated manuscripts. "The Blackbird of Belfast Lough", a fragment of syllabic verse probably dating from the 9th century, has inspired reinterpretations and translations in modern times by John Montague, John Hewitt, Seamus Heaney, Ciaran Carson, and Thomas Kinsella, as well as a version into modern Irish by Tomás Ó Floinn.
