Marianus Scotus
Marianus Scotus a noted ecclesiastic, was born in Ireland or Scotland A.D. 1028; became a monk; traveled on the Continent in 1058, especially in Germany, and frequented the German monasteries of Cologne, Fulda, and Mentz, and died A.D. 1086. Marianus Scotus was the first to correct the inaccurate chronologies of the chronicles in his Chronicon (3 vols. to 1084; continued by Dodechin up to 1200). It is published among the Scriptores rerum Germanlicarun by Struve and others. The most valuable is the 3d volume, treating of the Carlovingian and following emperors.
