Caesar and, by extension, to his adopted son Augustus, by immortalizing the tradition that renamed Aeneas' son, Ascanius (called Ilus from Ilium, meaning Troy), Iulus, thus making him an ancestor of the gens Julia, the family of Julius Caesar, and many other great imperial descendants as part of the prophecy given to him in the Underworld. (The meter shows that the name "Iulus" is pronounced as three syllables, not as "Julus".) The perceived deficiency of any account of Aeneas' marriage to Lavinia or his founding of the Roman race led some writers, such as the 15th-century Italian poet Maffeo Vegio (through his Thirteenth Book of the Aeneid widely printed in the Renaissance), Pier Candido Decembrio (whose attempt was never completed), Claudio Salvucci (in his 1994 epic poem The Laviniad), and Ursula K. Le Guin (in her 2008 novel Lavinia) to compose their own supplements. Despite the polished and complex nature of the Aeneid (legend stating that Virgil wrote only three lines of the poem each day), the number of half-complete lines and the abrupt ending are generally seen as evidence that Virgil died before he could finish the work. Some legends state that Virgil, fearing that he would die before he had properly revised the poem, gave instructions to friends (including the current emperor, Augustus) that the Aeneid should be burned upon his death, owing to its unfinished state and because he had come to dislike one of the sequences in Book VIII, in which Venus and Vulcan made love, for its nonconformity to Roman moral virtues. The friends did not comply with Virgil's wishes and Augustus himself ordered that they be disregarded. After minor modifications, the Aeneid was published. Because it was composed and preserved in writing rather than orally, the text exhibits less variation than other classical epics. Style As with other classical Latin poetry, the meter is based on the length of syllables rather than the stress, though the interplay of meter and stress is also important. Virgil also incorporated such poetic devices as alliteration, onomatopoeia, synecdoche, and assonance. Furthermore, he uses personification, metaphor, and simile in his work, usually to add drama and tension to the scene. An example of a simile can be found in book II when Aeneas is compared to a shepherd who stood on the high top of a rock unaware of what is going on around him. It can be seen
