Virgil was an ancient Roman poet of the Augustan period. He composed three of the most famous poems in Latin literature: the Eclogues the Georgics, and the epic Aeneid. "Aeneid" is a Latin epic poem that tells the legendary story of Aeneas, a Trojan who fled the fall of Troy and travelled to Italy, where he became the ancestor of the Romans. It comprises 9,896 lines in dactylic hexameter. The first six of the poem's twelve books tell the story of Aeneas' wanderings from Troy to Italy, and the poem's second half tells of the Trojans' ultimately victorious war upon the Latins, under whose name Aeneas and his Trojan followers are destined to be subsumed. "The Eclogues" – Taking as his generic model the Greek bucolic poetry of Theocritus, Virgil created a Roman version partly by offering a dramatic and mythic interpretation of revolutionary change at Rome in the turbulent period between roughly 44 and 38 BC. Virgil's book contains ten pieces, each called not an idyll but an eclogue, populated by and large with herdsmen imagined conversing and performing amoebaean singing in largely rural settings, whether suffering or embracing revolutionary change or happy or unhappy love. Performed with great success on the Roman stage, they feature a mix of visionary politics and eroticism that made Virgil a celebrity, legendary in his own lifetime. "The Georgics" – The subject of the poem is agriculture; but far from being an example of peaceful rural poetry, it is a work characterized by tensions in both theme and purpose. The Georgics is considered Virgil's second major work, following his Eclogues and preceding the Aeneid. The poem draws on a variety of prior sources and has influenced many later authors from antiquity to the present. The Georgics consists of 2,188 hexametric verses divided into four books. The yearly timings by the rising and setting of particular stars were valid for the precession epoch of Virgil's time, and so are not always valid now.
