ALTING (Henry), professor of divinity at Heidelberg and Groningen, was born at Embden in 1583, of a family which had been long conspicuous in Frisland. His father, Menso Alting, was the first, who, with two others, preached the reformation in the territory of Groningen, about the year 1566, under the tyrannical government of the duke of Alva; and the first that preached in the great church of Groningen, after the reduction of that town by the States General in 1594. Henry was chosen, in 1605, preceptor to the three young counts of Nassau, Solms, and Izenberg. After various difficulties, he settled at Groningen, where he continued till his death, August 25. 1644. He was a sound protestant divine, a pious Christian, a useful member of society in many respects, and one who suffered much for the truth. Most of his works were never published; those which have been are the following: Note in decadem problematum J. Behm, 1618. Loci communes explicatio catecheseos Palatine, 1646, in 3 vols. Exegesis Augustana confes. 1647. Methodus theologiae, 1650. It appears from the catalogue of his works annexed to his life, that the Medulla hist. prophane, published by Dr Pareus, was composed by Alting. The most remarkable piece among Alting's MMS. is, The ecclesiastical history of the Palatinate, from the reformation to the administration of John Casimir.
