CORRADO di WALDHAUSEN (C. d'AUSTRIA). - Regular canon, born in Upper Austria certainly before 1320, died in Prague on 8 Dec. 1369. He was a canon at Waldhausen; having become a priest, he worked as a preacher for 15 years.
In his sermons he vigorously advocated a radical reform of clergy and people. He achieved good results, but his overly impassioned and biting speech brought upon him the charge of heresy, from which he had to clear himself in Rome in 1359. He therefore composed his Apologia, which he published in 1365; the principal information about his life is drawn from this work. C. also held the office of parish priest in various places. None of his sermons has survived. Besides the aforementioned Apologia, seventy-three manuscript discourses are known by him, transmitted as Postilla studentium Universitatis Pragensis, and a treatise De arte oratoria, likewise still in manuscript.
