its deficiency could not be excused. And lastly, under the Antonines (and earlier [37]), disgust at the false taste of the day produced an irrational reaction in favour of the archaic modes of thought and expression, so that Gellius, for instance, extols the simplicity, sweetness, or noble vigour of writings in which we, like Cicero, should see only jejune and rugged immaturity. [38] Pliny speaks of Piso as a weighty author (_gravis auctor_), and Pliny's penetration was not easily warped by style or want of style. We may conclude, on the whole, that Piso, though often misled by his want of imagination, and occasionally by inaccuracy in regard to figures, [39] brought into Roman history a rational method, not by any means so original or excellent as that of Cato, but more on a level with the capacities of his countrymen, and infinitely more productive of imitation. The study of Greek rhetoric had by this time been cultivated at Rome, and the difficulty of composition being materially lightened [40] as well as its results made more pleasing, we are not surprised to find a number of authors of a somewhat more pretentious type. VENNONIUS, CLODIUS LICINUS, C. FANNIUS, and GELLIUS are little more than names; all that is known of them will be found in Teuffel's repertory. They seem to have clung to the title of annalist though they had outgrown the character. There are, however, two names that cannot be quite passed over, those of SEMPRONIUS ASELLIO and CAELIUS ANTIPATER. The former was military tribune at Numantia (133 B.C.), and treated of that campaign at length, in his work. He was killed in 99 B.C. [41] but no event later than the death of Gracchus (121 B.C.) is recorded as from him. He had great contempt for the old annalists, and held their work to be a mere diary so far as form went; he professed to trace the motives and effects of actions, rather, however, with the object of stimulating public spirit than satisfying a legitimate thirst for knowledge. He had also some idea of the value of constitutional history, which may be due to the influence of Polybius, whose trained intelligence and philosophic grasp of events must have produced a great impression among those who knew or read him.
