It will be seen from the above _résumé_ that the poem discusses several questions of great interest. Rising above the technicalities of the science, Manilius tries to preach a theory of the universe which shall displace that given by Lucretius. He is a Stoic combating an Epicurean. A close study of Lucretius is evidenced by numerous passages, [82] and the earnestness of his moral conclusions imitates, though it does not approach in impressiveness, that of the great Epicurean. Occasionally he imitates Horace, [83] much more often Virgil, and, in the legends, Ovid. [84] His technical manipulation of the hexameter is good, though tinged with monotony. Occasionally he indulges in licenses which mark a deficient ear [85] or an imperfect comprehension of the theory of quantity. [86] He has few archaisms, [87] few Greek words, considering the exigencies of his subject, and his vocabulary is greatly superior to his syntax; the rhetorical colouring which pervades the work shows that he was educated in the later taste of the schools, and neither could understand nor desired to reproduce the simplicity of Lucretius or Virgil. [88] CHAPTER V. PROSE-WRITERS OF THE AUGUSTAN PERIOD. Public oratory, which had held the first rank among studies under the Republic, was now, as we have said, almost extinct. In the earlier part of Augustus's reign, Pollio and Messala for a time preserved some of the traditions of freedom, but both found it impossible to maintain their position. Messala retired into dignified seclusion; Pollio devoted himself to other kinds of composition. Somewhat later we find MESSALINUS, the son of Messala, noted for his eloquent pleading; but as he inherited none of the moral qualities which had made his father dangerous, Augustus permitted him to exercise his talent. He was an intimate friend of Ovid, from whom we learn details of his life; but he frittered away his powers on trifling jests [1] and extempore versifying. The only other name worthy of mention is Q. HATERIUS, who from an orator became a noted declaimer. The testimonies to his excellence vary; Seneca, who had often heard him, speaks of the wonderful volubility, more Greek than Roman, which in him amounted to a fault. Tacitus gives him higher praise, but admits that his writings do not answer to his living fame, a persuasive manner and sonorous voice having been indispensible ingredients in his oratory. [2] The activity before given to the state was now transferred to the basilica. But as the full sway of rhetoric was not established until quite the close of Augustus's reign, we shall reserve our account of it for the next book, merely noticing the chief rhetoricians who flourished at this time. The most eminent were PORCIUS LATRO, FUSCUS ARELLIUS, and ALBUCIUS SILUS, who are frequently quoted by Seneca; RUTILIUS LUPUS, [3] who was somewhat younger; and SENECA, the father of the celebrated philosopher. [4] Fuscus was an Asiatic, and seems to have been one of the first who
