Dr. MOMMSEN has long been known and appreciated through his researches into the languages, laws, and institutions of Ancient Rome and Italy, as the most thoroughly versed scholar now living in these departments of historical investigation. To a wonderfully exact and exhaustive knowledge of these subjects, he unites great powers of generalization, a vigorous, spirited, and exceedingly graphic style and keen analytical powers, which give this history a degree of interest and a permanent value possessed by no other record of the decline and fall of the Roman Commonwealth. "Dr. Mommsen's work," as Dr. Schmitz remarks in the introduction, "though the production of a man of most profound and extensive learning and knowledge of the world, is not as much designed for the professional scholar as for intelligent readers of all classes who take an interest in the history of by-gone ages, and are inclined there to seek information that may guide them safely through the perplexing mazes of modern history." CRITICAL NOTICES. "A work of the very highest merit; its learning is exact and profound; its narrative full of genius and skill; its descriptions of men are admirably vivid. We wish to place on record our opinion that Dr. Mommsen's is by far the best history of the Decline and Fall of the Roman Commonwealth."--_London Times_. "Since the days of Niebuhr, no work on Roman History has appeared that combines so much to attract, instruct, and charm the reader. Its style--a rare quality in a German author--is vigorous, spirited, and animated. Professor Mommsen's work can stand a comparison with the noblest productions of modern history."--_Dr. Schmitz._ "This is the best history of the Roman Republic, taking the work on the whole--the author's complete mastery of his subject, the variety of his gifts and acquirements, his graphic power in the delineation of national and individual character, and the vivid interest which he inspires in every portion of his book. He is without an equal in his own sphere."--_Edinburgh Review_. "A book of deepest interest."--_Dean Trench_. ANOTHER GREAT HISTORICAL WORK. _The History of Greece,_ By Prof. Dr. ERNST CURTIUS.
