JABLONSKI, DANIEL-ERNEST, a learned Polish protestant divine, was born at Dantzic, on the 20th of November 1660. He commenced his studies at the gymnasium of Lissa, then attended the academical course of the university of Frankfort, and, after taking his degrees, visited Holland and England, in which last country he remained a year to hear the prelections of the Oxford professors. On his return he became successively minister of Magdeburg, Lissa, Königsberg, and Berlin; and was at length appointed ecclesiastical counsellor, and president of the Academy of Sciences at Berlin. He took great pains to effect an union between the Lutherans and Calvinists, and wrote some works which are esteemed. He died in 1741. His works consist of, 1. A German and Hebrew Catechism, 1708, in 4to; 2. Sermons in German, 1718, in 4to; 3. The History of the Consensus of Sendomir, in Latin, 1730; 4. Different writings, in Latin and German, in favour of the Protestants of Poland, amongst which may be mentioned, Afflicted Thorn, or a Relation of what passed in that City since the 16th of July 1724, of which there is a French translation by Beausobre, Amsterdam, 1726, in 12mo, now very rare.
