DIONYSIUS (Halicarnassensis), a celebrated historian, and one of the most judicious critics of antiquity, was born at Halicarnassus; and went to Rome after the battle of Actium, where he staid 22 years, under the reign of Augustus. He there composed in Greek, his History of the Roman Antiquities, in 20 books, of which the first 11 only are now remaining. There are also still extant several of his critical works. The best edition of the works of this author is that of Oxford, in 1704, in Greek and Latin, by Dr Hudson.
