But while satire, from one side, is to be regarded as the directest expression of Roman public life, it was, at the same time, the truest exponent of the character, pursuits, and interests of the individual writer. The old definition of it by a Latin grammarian, 'Carmen maledicum et ad carpenda hominum vitia compositum,' is quite inapplicable to those familiar writings of Horace, in which he gives a pleasant account of his habits and mode of life in town and country, or that in which he humorously narrates his various adventures on his journey to Brundisium. The writings of Horace and Lucilius bore a more varied and miscellaneous character than that of the satire of the Empire or of modern times. Horace expresses his opinions and feelings in the form sometimes of a dialogue, sometimes of a familiar epistle, sometimes of a discourse put into the mouth of another, sometimes of a moral disquisition. He makes abundant use of fables, anecdotes, personal portraiture, real and imaginary, autobiography, and self-analysis. The fragments of Lucilius, and the notices about him in ancient authors, prove that in these respects Horace followed in his footsteps. The testimony of the lines-- Ille velut fidis arcana sodalibus olim, etc., implies that Lucilius used his satire as a natural vehicle for expressing everything that interested him, in his own life and in the circumstances of his time. In regard to the miscellaneous nature of the topics treated by him, and the frankness of his personal revelations, his truest modern parallel is Montaigne,--the father of the prose essay, which has performed the function of the older Roman satire more completely than even the poetical satire of modern times. Among the poets of the Republic, whose works have reached us only in fragments, Lucilius is only second in importance to Ennius. Roman Satire owes as much in form, substance, and spirit to him as the Roman epic does to the older poet. While Ennius represents the highest mood of Rome, and first gave expression to that imperial idea which ultimately realised itself in history, Lucilius is the exponent of her ordinary moods, manifested in the streets and the forum, and of those internal dissensions and destructive forces by which her political life was agitated and ultimately overthrown. His personal characteristics and literary position can be inferred with nearly as much certainty as those of Ennius. The most important external evidence from which we form our idea of him is that of Horace and Cicero. But the numerous fragments of his writings bear a strong impress of his personality. From the confirmation which they give to other testimonies, we may endeavour to recover some of the lines and colours of that 'votiva tabula' which the contemporaries of Horace found in his books, and to realise the nature of the work performed by him and of the influence which he exercised over his countrymen.
