OLEARIUS (Godfrey), son of Godfrey Olearius, D. D. superintendent of Halle in Saxony, was born there in 1639. He became professor of Greek at Leipzig; and showed his abilities in that language by 52 excursions on the dominical epistles, and upon those parts of the epistles in the New Testament which are read in the public exercises, and which among the Lutherans are the subject of part of their sermons. He discharged the most important posts in the university, and among other dignities was ten times rector of it. His learning and industry were displayed in 106 theological disputations, 61 in philosophy, some programmas upon difficult points, several speeches and theological counsels; which make two thick volumes: beside his Moral Theology, his Introduction to Theology, which treats of cases of conscience, and his Hermeneutica Sacra. He lived to a good old age, dying in 1713. His eldest son of his own name, was a man of genius and learning, a professor in the same university, who published several works, but died young of a consumption before his father.
