Besides Epicurus and Empedocles Lucretius mentions Democritus and Anaxagoras, and speaks even of those whom he confutes as 'making many happy discoveries by divine inspiration,' and as 'uttering their responses from the shrine of their own hearts with more holiness and truth than the Pythia from the tripod and laurel of Apollo.' The reverence which other men felt in presence of the ceremonies of religion he feels in presence of the majesty of Nature; and to the interpreters of her meaning he ascribes the holiness claimed by the ministers of religion. Thus, to a doctrine of Democritus he applies the words 'sancta viri sententia.' The divinest faculty in man is that by which truth is discovered. The highest office of poetry is to clothe the discoveries of thought with the charm of graceful expression and musical verse[33]. Of other Greek authors, Homer and Euripides are those of whom we find most traces in the poem. To the first he awards a high pre-eminence above all other poets,-- Adde repertores doctrinarum atque leporum, Adde Heliconiadum comites; quorum unus Homerus Sceptra potitus eadem aliis sopitu' quietest[34]. The passages in which Lucretius imitates him show how clearly he recognised his exact vision of outward things, and his true appreciation of the moral strength and dignity of man. The frequent imitations of Euripides[35] show that while he felt the spell of his pathos, he was also attracted by the poetic mould into which the tragic poet has cast the physical speculations of Anaxagoras. Allusion is made in tones of indifference or disparagement to other poets of Greece, as having, in common with the painters of former times, given shape and substance to the superstitious fancies of mankind. It is characteristic of his powerful and independent genius, that, unlike the younger poets of his generation, he adheres to the older writers of the great days of Greece, and acknowledges no debt to the Alexandrine School. Although amply furnished with the knowledge necessary for the performance of his task, he is a poet of original genius much more than of learning and culture: and he is thus more drawn to those who acted on him by a kindred power, than to those who might have served him as models of poetic form or repertories of poetic illustration. The strength of his understanding attracted him to some of the great prose-writers of Greece, by whom that quality is most conspicuously displayed; notably to Thucydides, whom he has closely followed in his account of the 'Plague at Athens,' and, as has been shown by Mr. Munro, to Hippocrates. The kind of attraction which the last of these has for him confirms the criticism of Goethe, that Lucretius shows the observing faculty of a physician, as well as of a poet.
