Rh "On the Nature of Things," he drew quite as largely, but in another field. Virgil is said to have been born on the very day of Lucretius's death, and he had an intense admiration for both his diction and his philosophy. There are passages in Virgil's writings which would seem to show that his greatest ambition would have been to have sung, like Lucretius, of the secrets of nature, rather than either of heroic legends or of country life. And here and there, throughout these books of Georgics, wherever he has the opportunity, he forgets the farmer in the natural philosopher, and breaks off in the midst of some practical precepts to indulge in speculations on the hidden causes of nature's operations, which would have sorely puzzled a Roman country gentleman or his bailiff, if we could suppose that the work was really composed with a view to their practical instruction.

He addresses his poem to his noble patron Mæcenas. And amongst the long list of divine powers whom, as the guardians of fields and flocks, he invokes to aid his song, he introduces the present Autocrat of Rome.

Thou, Cæsar, chief, where'er thy choice ordain,

To fix 'mid gods thy yet unchosen reign—

Wilt thou o'er cities stretch thy guardian sway,

While earth and all her realms thy nod obey?

The world's vast orb shall own thy genial power,

Giver of fruits, fair sun, and favouring shower;

Before thy altar grateful nations bow,

And with maternal myrtle wreathe thy brow.

O'er boundless ocean shall thy power prevail,

Thee her sole lord the world of waters hail?
