Otto was born in Klosterneuburg as the fifth son of Leopold III, margrave of Austria, by his wife Agnes, daughter of Emperor Henry IV.[1] Having entered the Cistercian order, Otto convinced his father to found Heiligenkreuz Abbey in 1133, thus bringing literacy and sophisticated agriculture (including wine making) to the region that would become Vienna.This diocese, and indeed the whole of Bavaria, was then disturbed by the feud between the Welfs and the Hohenstaufen, and the church was in a deplorable condition; but a great improvement was brought about by the new bishop in both ecclesiastical and secular matters.The chronicle, which was held in very high regard by contemporaries, covers the years up until 1146, and from this date until 1209 it was continued by Otto, abbot of St Blasius (died 1223).[3] In the Chronica, Otto reports a meeting he had with Bishop Hugh of Jabala, who told him of a Nestorian Christian king in the east named Prester John.It is not confined to German affairs, as the author digresses to tell of the preaching of Bernard of Clairvaux, of his zeal against the heretics, and of the condemnation of Pierre Abélard; he also discourses on philosophy and theology.
