(Matthias), b. Oldens worth, in Holstein, 1645. He early lost his parents, and was brought to an uncle at Königsberg, where he studied philosophy. He took to the adventurous life of a wandering scholar and propagated his principles in many places. In 1674 he preached Atheism publicly at Jena, in Germany, and had followers who were called “Gewi ener,” from their acknowledging no other authority but conscience. It is said there were seven hundred in Jena alone. What became of him and them is unknown. A letter dated from Rome gives his principles. He denied the existence of either God or Devil, deemed churches and priests usele , and held that there is no life beyond the present, for which conscience is a sufficient guide, taking the place of the Bible, which contains great contradictions. He also wrote two dialogues.
