Compiled ca. 807 in the Irish archdiocese of Armagh, the Book of Armagh is a work written in Latin and ancient Gaelic which contains almost the whole NT, some ecclesiastical texts, but esp. some documents regarding St. Patrick c. 373 461 and his mission: two Lives, an incomplete collection of memoirs Dicta Patricii, in part ascribable to Trechn, and an abbreviated version of the Confessio, written by the then-aged Patrick to thank God and explain the meaning of his episcopate, in some ways closely following Augustine’s Confessions.
