Virgil's Georgics, considered to be one of the great poems of Western literature, is ostensibly a didactic poem on agriculture. Challenging this idea, the late Sir Roger Mynors argues that the poem's true subject is humanity and its place in nature and society. The poem is also a landmark in the use of the natural world as material for literature and of special interest because the poet draws not only on his own experience but also on his wide reading of Greek poetry. This commentary examines Virgil's meaning and choice of expression to provide a fuller understanding of the poetry.
