It was only in its lighter forms that poetry continued to make progress. The _Silvæ_ of Statius, which were shorter occasional poems in elegiac or lyric measures thrown off at odd moments with ease and rapidity, are far more interesting than his frigid epic. Martial, the Spanish writer of _vers de société_, has a pretty wit that is often surprisingly modern in its tone. Certainly Juvenal towers over all others who have attempted satire. Horace had been content with an easy familiarity of tone which might wheedle a friend into the path of good sense by poking fun at his follies. Juvenal thunders his denunciations of wickedness with a moral heat which is surprising in an age often accused of feebleness. He does, however, resemble Lucan in spoiling some of his effects by want of light and shade, by a too-persistent flow of rhetoric. He seems unable to distinguish between harmless follies like playing the flute and real delinquencies like murdering one’s mother. He clearly draws far too black a picture of the men and morals of his day. But the pulpit from which he preaches is a high one. If Juvenal is supreme over the poets of his time, Tacitus is as clearly monarch of the prose-writers. He was continuing the work of Livy and writing from the same republican standpoint. But for history-writing he had certainly discovered a finer style of rhetoric. Both are rhetoricians first and historians a long way after, but the packed epigrams of Tacitus say more in a line than Livy is capable of thinking in a chapter. In describing a battle, a riot, or a panic, or in painting some tragic scene, such as the death of Vitellius, Tacitus is unequalled. The freedom that was permitted to him and Suetonius in depicting the crimes and follies of the earlier Cæsars affords remarkable evidence of the freedom of letters under Nerva, Trajan, and Hadrian. Here, again, it is necessary, as in the case of Juvenal, to beware of accepting too literally the severity of his criticisms upon the preceding generation. To praise the past at the expense of the present was one of the traditions of Roman literature. But Tacitus was the last of Rome’s great historians and his loss was irreparable.
