In reading the lives of the chief post-Augustan writers we are struck by the fact that many, if not most of them, held offices of state. The desire for peaceful retirement, characteristic of the early Augustans, the contentment with lettered leisure that signalises the poetry of the later Augustans, have both given place to a restless excitement, and to a determination to make the most of literature as an aid to a successful career. Hitherto we have observed two distinct classes of writers, and a corresponding double relation of politics and literature. The early poets, and again those of Augustus's era, were not men of affairs, they belonged to the exclusively literary class. The great prose writers on the contrary rose to political eminence by political conduct. Literature was with them a relaxation, and served no purpose of worldly aggrandisement. Now, however, an unhealthy confusion between the two provinces takes place. A man rises to office through his poems or rhetorical essays. The acquirements of a professor become a passport to public life. Seneca and Quintilian are striking and favourable instances of the school door opening into the senate: "Si fortuna volet fies de rhetore consul." [8] But nearly all the chief writers carried their declamatory principles into the serious business of life. This double aspect of their career produced two different types of talent, under one or other of which the great imperial writers may be ranged. Excluding men of the second rank, we have on the one side Lucan, Juvenal, and Tacitus, all whose minds have a strong political bias, the bias of old Rome, which makes them the most powerful though the most prejudiced exponents of their times. Of another kind are Persius, Seneca, and Pliny the elder. Their genius is contemplative and philosophical; and though two of them were much mixed in affairs, their spirit is cosmopolitan rather than national, and their wisdom, though drawn from varied sources, cannot be called political. These six are the representative minds of the period on which we are now entering, and between them reflect nearly all the best and worst features of their age. Quintilian, Statius, and Pliny the younger, represent a more restricted development; the first of them is the typical rhetorician, but of the better class; the second is the brilliant improvisatore and ingenious word-painter; the third the cultivated and amiable but vain, common-place, and dwarfed type of genius which under the Empire took the place of the "fine gentlemen" of the free Republic.
