Question: Os Lusíadas is frequently compared to a poem by Virgil written in which language ?

full_context: Document 1: Ascanius: Ascanius ( ) (said to have reigned 1176-1138 BC) a legendary king of Alba Longa and is the son of the Trojan hero Aeneas and Creusa, daughter of Priam. He is a character in Roman mythology, and has a divine lineage, being the son of Aeneas, who is the son of the goddess Venus and the hero Anchises, a relative of the king Priam; thus Ascanius has divine ascendents by both parents, being descendant of god Jupiter, his wife Juno and Dardanus. He is also an ancestor of Romulus, Remus and the Gens Julia. Together with his father, he is a major character in Virgil's "Aeneid", and he is depicted as one of the founders of the Roman race.
Document 2: Didone (opera): The plot is based on Virgil's "Aeneid" (Book 4 in particular), though Busenello, in his second libretto for Cavalli, replaces Dido's tragic suicide of Virgil with a happy ending in which Dido marries Iarbas, King of the Getuli, who saves Dido from herself after Aeneas abandons her. The action is divided into a prologue and 3 acts.
Document 3: Livius Andronicus: Lucius Livius Andronicus (c. 284 – c. 205 BC) was a Greco-Roman dramatist and epic poet of the Old Latin period. He began as an educator in the service of a noble family at Rome by translating Greek works into Latin, including Homer's "Odyssey". They were meant at first as educational devices in the school he founded. He wrote works for the stage—both tragedies and comedies—which are regarded as the first dramatic works written in the Latin language of ancient Rome. His comedies were based on Greek New Comedy and featured characters in Greek costume. Thus, the Romans referred to this new genre by the term comoedia palliata (fabula palliata). The Roman biographer Suetonius later coined the term "half-Greek" of Livius and Ennius (referring to their genre, not their ethnic backgrounds). The genre was imitated by the next dramatists to follow in Andronicus' footsteps and on that account he is regarded as the father of Roman drama and of Latin literature in general; that is, he was the first man of letters to write in Latin. Varro, Cicero, and Horace, all men of letters during the subsequent Classical Latin period, considered Livius Andronicus to have been the originator of Latin literature. He is the earliest Roman poet whose name is known.
Document 4: Aeneas: In Greco-Roman mythology, Aeneas ( ; Greek: Αἰνείας, "Aineías", possibly derived from Greek αἰνή meaning "praised") was a Trojan hero, the son of the prince Anchises and the goddess Venus (Aphrodite). His father was a first cousin of King Priam of Troy (both being grandsons of Ilus, founder of Troy), making Aeneas a second cousin to Priam's children (such as Hector and Paris). He is a character in Greek mythology and is mentioned in Homer's "Iliad". Aeneas receives full treatment in Roman mythology, most extensively in Virgil's "Aeneid," where he is an ancestor of Romulus and Remus. He became the first true hero of Rome. Snorri Sturluson identifies him with the Norse Æsir Vidarr.
Document 5: Pedro Álvares Cabral: Pedro Álvares Cabral (] ] ; c. 1467 or 1468 – c. 1520) was a Portuguese nobleman, military commander, navigator and explorer regarded as the discoverer of Brazil. Cabral conducted the first substantial exploration of the northeast coast of South America and claimed it for Portugal. While details of Cabral's early life are unclear, it is known that he came from a minor noble family and received a good education. He was appointed to head an expedition to India in 1500, following Vasco da Gama's newly opened route around Africa. The object of the undertaking was to return with valuable spices and to establish trade relations in India—bypassing the monopoly on the spice trade then in the hands of Arab, Turkish and Italian merchants. Although the previous expedition of Vasco da Gama to India, on its sea route, recorded signs of land west of the southern Atlantic Ocean (in 1497), Cabral is regarded as the first captain who ever touched four continents, leading the first expedition that united Europe, Africa, America, and Asia.
Document 6: Aeneid: The Aeneid ( ; Latin: "Aeneis" ] ) is a Latin epic poem, written by Virgil between 29 and 19 BC, that tells the legendary story of Aeneas, a Trojan who 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's 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.
Document 7: Os Lusíadas: Os Lusíadas (] ), usually translated as The Lusiads, is a Portuguese epic poem by Luís Vaz de Camões (sometimes anglicized as "Camoëns"). It is often regarded as the most important work of Portuguese literature and is frequently compared to the Aeneid, Virgil's great epic poem. The work celebrates the discovery of a sea route to India by the Portuguese explorer Vasco da Gama (1469–1524). The ten cantos of the poem are in ottava rima and total 1,102 stanzas.
Document 8: Adamastor: Adamastor is a Greek-type mythological character famed by the Portuguese poet Luís de Camões in his epic poem "Os Lusíadas" (first printed in 1572), as a symbol of the forces of nature Portuguese navigators had to overcome during their discoveries.
Document 9: The Twelve of England: The Twelve of England (in Portuguese: Os Doze de Inglaterra) is a Portuguese chivalric legend of 15th-century origin, famously related by the poet Luís de Camões in his 1572 "Os Lusíadas" (Canto VI). It tells the story of twelve Portuguese knights who travelled to England at the request of twelve English ladies to avenge their insult by a group of English knights.
Document 10: The Old Man of Restelo: The Old Man of Restelo ("Velho do Restelo"), some translations also refer as The Old Man of Belem, is a character introduced by the Portuguese epic poet Luís de Camões in Canto IV of his work the Lusíadas. The Old Man of Restelo is variously interpreted as a symbol of the pessimists, or those who did not believe in the likely success of the then upcoming Portuguese voyages of 'discovery'. He comes up just before the first expedition to India with warnings about the odyssey that was about to happen:
Document 11: Portuguese literature: Portuguese literature is, generally speaking, literature written in the Portuguese language, particularly by citizens of Portugal; it may also refer to literature written by people living in Portugal, Brazil, Angola and Mozambique, as well as other Portuguese-speaking countries. An early example of Portuguese literature is the tradition of a medieval Galician-Portuguese poetry, originally developed in Galicia and northern Portugal. The literature of Portugal is distinguished by a wealth and variety of lyric poetry, which has characterized it from the beginning of its language, after the Roman occupation; by its wealth of historical writing documenting Portugal’s rulers, conquests, and expansion; by the then considered Golden Age of the Renaissance period of which it forms part the moral and allegorical Renaissance drama of Gil Vicente, Bernardim Ribeiro, Sá de Miranda and especially the great 16th-century national epic of Luís de Camões, author of national and epic poem "Os Lusíadas" (The Lusiads).
Document 12: Luís de Camões: Luís Vaz de Camões (] ; sometimes rendered in English as Camoens or Camoëns (e.g. by Byron in "English Bards and Scotch Reviewers"), ; c. 1524 or 1525 – 10 June 1580), is considered Portugal's and the Portuguese language's greatest poet. His mastery of verse has been compared to that of Shakespeare, Vondel, Homer, Virgil and Dante. He wrote a considerable amount of lyrical poetry and drama but is best remembered for his epic work "Os Lusíadas" ("The Lusiads"). His collection of poetry "The Parnasum of Luís de Camões" was lost in his lifetime. The influence of his masterpiece "Os Lusíadas" is so profound that Portuguese is sometimes called the "language of Camões".
Document 13: On First Looking into Chapman's Homer: "On First Looking into Chapman's Homer" is a sonnet written by the English Romantic poet John Keats (1795–1821) in October 1816. It tells of the author's astonishment while reading the works of the ancient Greek poet Homer as freely translated by the Elizabethan playwright George Chapman.
Document 14: Trojan War: In Greek mythology, the Trojan War was waged against the city of Troy by the Achaeans (Greeks) after Paris of Troy took Helen from her husband Menelaus, king of Sparta. The war is one of the most important events in Greek mythology and has been narrated through many works of Greek literature, most notably through Homer's "Iliad". The "Iliad" relates four days in the tenth year of the decade-long siege of Troy; the "Odyssey" describes the journey home of Odysseus, one of the war's heroes. Other parts of the war are described in a cycle of epic poems, which have survived through fragments. Episodes from the war provided material for Greek tragedy and other works of Greek literature, and for Roman poets including Virgil and Ovid.
Document 15: Odyssey: The Odyssey ( ; Greek: Ὀδύσσεια "Odýsseia", ] in Classical Attic) is one of two major ancient Greek epic poems attributed to Homer. It is, in part, a sequel to the "Iliad", the other work ascribed to Homer. The "Odyssey" is fundamental to the modern Western canon, and is the second-oldest extant work of Western literature; the "Iliad" is the oldest. Scholars believe the "Odyssey" was composed near the end of the 8th century BC, somewhere in Ionia, the Greek coastal region of Anatolia.
