1911 Encyclopædia Britannica/Marianus Scotus
MARIANUS SCOTUS (1028-1082 or 1083), chronicler (who must be distinguished from his namesake Marianus Scotus, d. 1088, abbot of St Peter’s, Regensburg), was an Irishman by birth, and called Moelbrigte, or servant of Bridget. He was educated by a certain Tigernach, and having become a monk he crossed over to the continent of Europe in 1056, and his subsequent life was passed in the abbeys of St Martin at Cologne and of Fulda, and at Mainz. He died at Mainz, on the 22nd of December 1082 or 1083.
Marianus wrote a Chronicon, which purports to be a universal history from the creation of the world to 1082. The Chronicon was very popular during the middle ages, and in England was extensively used by Florence of Worcester and other writers. It was first printed at Basel in 1559, and has been edited with an introduction by G. Waitz for the Monumenta Germaniae historica. Scriptores (Bd. v.). See also W. Wattenbach, Deutschlands Geschichtsquellen (Bd. ii., 1894).
