The MS. from which the following extracts are taken is a beautiful vellum codex, substantially bound in dark red stamped morocco leather, with plain brass clasps, numbered 1586, 4to, Gl. Kong. Saml. (Old Royal Collection). It was written in 1488, at Mariager Cloister, near Aarhus in Jutland, by a monk residing there named Niels Morgensen, by order of the Prioress, Elizabeth Herman's daughter, as we are informed at the end of each part. It is the only text known. It contains, in addition to the portions now published, which form the second and fourth parts respectively, (I) A letter from St. Eusebius to Domacius, Bishop of Portoci, and Theodosius, a Roman Senator, announcing the death of St. Jerome, (III) Cyril's reply to St. Augustine's letter, and (V) A Life of St. Katharine of Siena, which last comprises almost a third of the whole.
