Virgil
Chances are that The Ecologues will not be on your exam, though they were very important for later poets like Edmund Spenser. The Aeneid will be on the exam, though it may only account for a question or two.
Aeneid
The Aeneid is a Latin epic written by Virgil in the 1st century BC (between 29 and 19 BC) that tells the legendary story of Aeneas, a Trojan who traveled to Italy where he became the ancestor of the Romans. It is written in dactylic hexameter.
Virgil begins his poem with a statement of his theme (Arma virumque cano…, "I sing of arms and the man...") and an invocation to his Muse (Musa, mihi causas memora…, "O Muse, relate to me the reasons…"). He then explains the cause of the principal conflict of the plot; in this case, the resentment held by Juno against the Trojan people. This is in keeping with the style of the Homeric epics, except in that Virgil states the theme and then invokes his Muse, whereas Homer invokes the Muse and then states the theme.
Also in the manner of Homer, the story proper begins in medias res, with the Trojan fleet in the eastern Mediterranean, heading in the direction of Italy. Juno stirs up a storm which is on the verge of sinking the fleet. Neptune takes notice: although he himself is no friend of the Trojans, he is infuriated by Juno's intrusion into his domain, and stills the winds and calms the waters. The fleet takes shelter on the coast of Africa, where Aeneas gains the favor of Dido, queen of Carthage, a city which has only recently been founded by refugees from Tyre and which will later become Rome's greatest enemy.
At a banquet given in the honor of the Trojans, Aeneas recounts the events which occasioned the Trojans' fortuitous arrival. He begins the tale shortly after the events described in the Iliad, and tells of the end of the Trojan War, the ruse of the Trojan Horse, the sack of Troy by the Greek armies, and his escape with his son Ascanius and father Anchises, his wife Creusa having been separated from the others and subsequently killed in the general catastrophe. She was later turned into a minor goddess. He tells of how, rallying the other survivors, he built a fleet of ships and made landfall at various locations in the Mediterranean (including Thrace, Crete and Epirus) before being divinely advised to seek out the land of Italy (also known as Ausonia or Hesperia), where his descendants would not only prosper, but in time rule the entire known world. The fleet reached as far as Sicily and was making for the mainland, until Juno raised up the storm which drove it back across the sea to Carthage.
During the banquet, Dido realizes that she has fallen madly in love with Aeneas, although she had previously sworn fidelity to the soul of her late husband, Sychaeus, who was murdered by her cupidinous brother Pygmalion. Juno seizes upon this opportunity to make a deal with Venus, Aeneas' mother, with the intention of distracting him from his destiny of founding a city in Italy. Aeneas is inclined to return Dido's love, and during a hunting expedition, a storm drives them into a cave in which Aeneas and Dido presumably have sex, an event that Dido takes to indicate a marriage between them. But when Jupiter sends Mercury to remind him of his duty, he has no choice but to part. Her heart broken, Dido commits suicide by stabbing herself upon a pyre with a sword. Before dying, she predicts eternal strife between Aeneas's people and hers; "rise up from my bones, avenging spirit" is an obvious invocation to Hannibal. Looking back from the deck of his ship, Aeneas sees Dido's funeral pyre's smoke and knows its meaning only too clearly. However, destiny calls and the Trojan fleet sails on to Italy.
Aeneas's father Anchises having been hastily interred on Sicily during the fleet's previous landfall there, the Trojans returned to the island to hold funeral games in his honor. Eventually, the fleet lands on the mainland of Italy and further adventures ensue. Aeneas descends to the underworld through an opening at Cumae, where he speaks with the spirit of his father and has a prophetic vision of the destiny of Rome. Returning to the land of the living, he leads the Trojans to settle in the land of Latium, where he courts Lavinia, the daughter of king Latinus. A war ensues between the Trojans and some of the indigenous peoples of Italy, which is brought to a close when Lavinia's rejected suitor Turnus, king of the Rutuli, challenges Aeneas to a duel in which Turnus is slain.
The Eclogues
Written in around 37 BC, it consists of ten poems with a rural setting. (For this reason, they are sometimes known as "The Bucolics".) Most of the individual poems are in the form of conversations between characters with names such as "Tityrus" (supposedly representing Virgil himself), "Meliboeus", "Menalcas" and "Mopsus".
