This relation to Memmius is the only additional fact which an examination of the poem brings into light. Nothing is learned from it of the poet's parentage, his education, his favourite places of residence, of his career, of his good or evil fortune. There were eminent Epicurean teachers at Athens and Rome (Patro, Phaedrus, Philodemus, etc.) during his youth and manhood, but it is useless to ask what influence of teachers or personal experience induced him to become so passionate a devotee of the doctrines of Epicurus. Yet though no direct reference to his circumstances is found in his writings, we may yet mark indirect traces of the impression produced upon him by the age in which his youth and manhood were passed; we seem to catch some glimpses of his habitual pursuits and tastes, to gain some real insight into his being, to apprehend the attitude in which he stood to the great teachers of the past, and to know the man by knowing the objects in life which most deeply interested him. Nothing, we may well believe, was further from his wish or intention than to leave behind him any record of himself. No Roman poet has so entirely sunk himself and the remembrance of his own fortunes in absorption in his subject. But his strong personal force and individuality have penetrated deeply into all his representation, his reasoning, and his exhortation. From the beginning to the end of the poem we feel that we are listening to a living voice speaking to us with the direct impressiveness of personal experience and conviction. No writer ever used words more clearly or more sincerely: no one shows a greater scorn for the rhetorical artifices which disguise the lack of meaning or insinuate a false conclusion by fine-sounding phrases:-- Quae belle tangere possunt Auris et lepido quae sunt fucata sonore[12]. The union of an original and independent personality with the utmost sincerity of thought and speech is a characteristic in which Lucretius resembles Thucydides. It is this which gives to the works of both, notwithstanding their studied self-suppression, the vivid interest of a direct personal revelation. The tone of many passages in the poem clearly indicates that Lucretius, though taking no personal part in the active politics of his age, was profoundly moved by the effects which they produced on human happiness and character. Thus the lines at iii. 70-74-- Sanguine civili rem conflant, etc.-- recall the thought and spectacle of crime and bloodshed vividly presented to him in the impressible years of his youth[12]. Other passages are an immediate reflexion of the disturbance and alarm of the times in which the poem was written. Thus the opening lines of the second book, which contrast the security of the contemplative life with the strife of political and military ambition, seem to be suggested by the action of what is sometimes called the first triumvirate. The lines-- Si non forte tuas legiones per loca campi, etc.--
