Whether Silius committed his philosophic dialogues and speeches to writing or not, we cannot say. His only preserved work is his epic poem entitled
Punica, about the Second Punic War (218–201 BC) in seventeen books, comprising some twelve thousand lines, making it the longest preserved poem in Latin literature.
The Punica by Raphael is based on an episode in Book 15 of the Punica'', the choice of Scipio. The dating of the
Punica has been a difficult issue for classical scholars, but two passages, 3.594 and 14.680ff., along with several poems of Martial cited above, indicate that it was composed sometime between 83 and 101, with Book 3 being dated to AD 84 and Book 14 around AD 96. Other books cannot be dated with any precision. The poem is divided into 17 books and is composed in
dactylic hexameter. It has been thought that the poem was initially planned in hexads and that the original intent was to round off the composition in 18 books. The poem takes Virgil as its primary stylistic and dramatic inspiration throughout; from its opening, the
Punica is configured as the continuation of Juno's grudge against Rome developed in the
Aeneid.
Livy and
Ennius are important sources for historical and poetic information, and Homer specifically is declared an important model by Silius who remarks of him at 12.788-9, "his [Homer's] poetry embraced the earth, sea, stars, and shades and he rivalled the Muses in song and Phoebus in glory." Lucan is also an important model for the writing of historical epic, geographical excursus, and Stoic tone, although Silius' approach toward the gods is much more traditional. The poem opens with a discussion of Juno's wrath against Rome on account of
Aeneas' treatment of
Dido and of
Hannibal's character and upbringing. Hannibal attacks
Saguntum and receives a Roman embassy. In Book 2, the Roman legation is heard at
Carthage, but Hannibal takes the city after the defenders heroically commit suicide. The Carthaginians are catalogued, Hannibal crosses the Alps, and
Jupiter reveals that the Punic War is a test of Roman manliness in Book 3. In 4 and 5 the Romans suffer defeat at
Ticinus,
Trebia, and
Lake Trasimene. Book 6 looks back to the exploits of
Marcus Atilius Regulus in the
First Punic War, while Book 7 describes
Fabius Verrucosus's delaying strategy. Books 8-10 describe in vivid detail the battle of
Cannae; Juno prevents Hannibal from marching on Rome. In Book 11, Hannibal's army winters in Capua, where Venus enfeebles them with luxury. Hannibal is defeated at
Nola in 12, emboldening the Romans. He makes an attempt on the city, but Juno stops him, revealing that the gods are against him. Book 13 reports the Romans' invasion of Capua and the death of two Scipios, which leads to
Scipio Africanus' journey to the underworld (
nekyia), his meeting with famous dead heroes, and a prophecy by the
Sibyl of Hannibal's defeat. In 14 the
Marcellus' successful Sicilian campaign and the siege-craft of
Archimedes are described. In 15, Scipio, choosing Virtue over Vice, has a successful campaign in Spain, while at the
Battle of the Metaurus, Hannibal's brother is killed. 16 describes the alliance between Rome and
Masinissa and Scipio's crossing into Africa, while 17 describes the bringing of the statue of
Cybele to Rome, Hannibal's stormy crossing into Africa, Juno's appeal to Jupiter for the life of Hannibal, and the
Battle of Zama. The poem ends with Scipio's triumphal return to Rome. Silius' style is unlike Virgil in that he does not focus on a few central characters but divides his action up between many significant heroes. This encourages him to present important events from the Roman past as a reflection on the characters and their actions in the poem's present, echoing the Roman tradition of using
exempla. While many important set pieces of epic are included, such as elaborated similes,
ekphrases of objects, such as Hannibal's shield in 2.391-456, a
nekyia, and divine participation in and prophecy of events, there are also important elements of historiography such as paired contrasting speeches and detailed geographical description. Allegory is particularly important in Silius, and he includes such figures as Fides, faith, in Book 2, Italia in 15, and Virtus and Voluptas also in Book 15, continuing a trend towards allegory which was significant in
Statius, Silius' contemporary. Silius' metrics and language can be closely compared to Virgilian usage, especially his use of
spondees. Stoicism and stoic ethical thought are significant themes in the
Punica. The war is configured as a trial of Roman
virtus which must be overcome with hard work, akin to the Stoic ideal of overcoming adversity with inner courage and trial. The "
choice of Hercules", a favorite Stoic parable, is given to Scipio in Book 15, and everywhere the war brings out moral lessons and discussions of Stoic concepts like emotion, reason, and destiny. ==Influence==
