ARNOLD, doctor of laws. This celebrated literary character was a native of Utrecht, and was born on the 1st of January 1684, and in which city he was afterwards professor of rhetoric and history. Gravius and Burmann taught him the belles lettres, and Cornelius Van Eck was his preceptor while he devoted his attention to the law. He succeeded Professor Burmann in the year 1716, and terminated his mortal career in 1748, in the 64th year of his age. He was an author of very considerable eminence, as the following publications sufficiently evince. His dissertation entitled, Disputatio Philologica. His de praefectis urbis, in 4to, proves him to have been an able philologist, and gave flattering indications of future eminence. Its intrinsic merit caused it to be reprinted at Frankfort-on-the-Oder, in 1759, by Professor Uhl, accompanied with a life of his learned author. His next work, entitled Disputatio de officio praefectorum pretorio, was published in the year 1707; and ten years after his C. Sili Italici Punicorum, in 17 books, to render which perfect and complete, nothing was omitted by this great man; many historical subjects being engraved for the purpose of elucidating the text, to which his own copious and learned annotations most powerfully contributed. His splendid edition of Livy, with a life of that eminent historian, will render his name immortal. It is entitled T. Livii Patavinii historiarum ab urbe condita libri, qui superant, omnes. Lugd. Batav. 1738 and 1746; 7 tom. The preface to this work is very long, and replete with erudition, giving a particular account of all the literary characters who have at different periods commented on the works of Livy. He took the edition of Gronovius for his model, as being in his estimation the most correct; but he made many important alterations on the authority of manuscripts which it is probable Gronovius had either never seen, or not taken the pains to consult. Upon the whole, this edition of Livy is at once the most elaborate, interesting, and instructive, ever given to the world, since into it he has introduced the criticisms of Duchier, Gronovius, Perizonius, and Sigonius, in addition to his own, which are certainly fraught with much literature and deep discernment.
