Vergil's Georgica is the culmination of a long tradition in antiquity of poems about agriculture, beginning with Hesiod in the eighth c. BC. His poem is a rich admixture of allusion to that tradition: didactic poem, eulogium of Augustus, the neoteric epyllion about Orpheus, Epicurean philosophy as presented by his predecessor and model, Lucretius. Thomas Jefferson imagined his gentleman farmer tilling his fields with a copy of the Georgics between the handles of the plowshare.
