Books by Bishop of Freising Otto

The 12th-century bishop Otto of Freising was an outstanding historian of his century. "The Two Cities" was his masterwork, spanning in time from Adam and Eve to the coming of the last days - which he believed were imminent.

The Deeds of Frederick Barbarossa is the "official biography" of German king and Holy Roman Emperor Frederick I. This historical firsthand account was begun by his maternal uncle, Bishop Otto of Freising, the leading medieval church figure and notable historian, and continued by a less well known cleric, Rahewin.
