HORNIUS (George), professor of history at Leyden, was born in the Palatinate, and died at Leyden in 1670. He was a little maniacal towards the end of his life; which disorder was supposed to be occasioned by the loss of 6000 florins he had entrusted with an alchemist at the Hague. His works are, 1. Historia Ecclesiastica ad an. 1666. This has been well esteemed. 2. De Originibus Americanis, 1652, 8vo. 3. Geographia Vetus & Nova. 4. Orbis Politicus. He was a man of vast reading, rather than great parts.
