with his promise at the outset he traces with much more effect the gradually increasing moral decadence. It is when Rome comes into contact with Asia that her virtue, already tried, collapses almost without a struggle. The army, once so steady in its discipline, riots in revelry, and marches against Antiochus with as much recklessness as if it were going to butcher a flock of sheep. [37] The soldiers even disobey orders in pillaging Phocaea; they become cowards, _e.g._, the Illyrian garrison surrenders to Perseus; and before long the abominable and detested oriental orgies gain a permanent footing in Rome. Meanwhile, the senate falls from its old standard, it ceases to keep faith, its generals boast of perfidy, [38] and the corrupted fathers have not the face to check them. [39] The epic of decadence proceeds to its _dénouement_, and if we possessed the lost books the decline would be much more evident. It must be admitted that in this department of his subject Livy paints with a master's hand. But nothing can atone for his signal deficiency in antiquarian and constitutional knowledge. He had (it has been said) a taste for truth, but not a passion for it. Had he gone into the _Aedes Nympharum_, he might have read on brass the so-called royal and tribunician laws; he might have read the treaties with the Sabines, with Gabii and Carthage; the Senatus Consulta and the Plebi Scita. Augustus found in the ruined temple of Jupiter Fucinus [40] the _spolia opima_ of Cossus, who was there declared to have been consul when he won them. All the authorities represented him as military tribune. Livy, it seems, never took the trouble to examine it. When he professes to cite an ancient document, it is not the document itself he cites but its copy in Fabius. He seems to think the style of history too ornate to admit such rugged interpositions, [41] and when he inserts them he offers a half apology for his boldness. This _dilettante_ way of regarding his sources deserves all the censure Niebuhr has cast on it. If it were not for the fidelity with which he has incorporated without altering his better-informed predecessors, the investigations of Niebuhr and his successors would have been hopelessly unverifiable. The student who wishes to learn the value of Livy for the history of the constitution should read the celebrated Lectures (VII. and VIII.) of Niebuhr's history. Their publication dethroned him, nor has he yet been reinstated. But it must be remembered that this censure does not attach to him in other aspects, for instance as a chronicler of Rome's wars, or a biographer of her worthies. As a geographer, however, he is untrustworthy; his description of Hannibal's march is obscure, and many battles are extremely involved. It is evident he was a clear thinker only on certain points; his preface, _e.g._, is intricate both in matter and manner.
