Chariton of Aphrodisias ( ; Greek: Χαρίτων Ἀφροδισεύς ) was the author of an ancient Greek novel probably titled "Callirhoe" (based on the subscription in the sole surviving manuscript), though it is regularly referred to as "Chaereas and Callirhoe" (which more closely aligns with the title given at the head of the manuscript).
 Recent evidence of fragments of the text on papyri suggests that the novel may have been written in the mid 1st century AD, making it the oldest surviving complete ancient prose romance and the only one to make use of apparent historiographical features for background verisimilitude and structure, in conjunction with elements of Greek mythology, as Callirhoë is frequently compared to Aphrodite and Ariadne and Chaereas to numerous heroes, both implicitly and explicitly.
 As the fiction takes place in the past, and historical figures interact with the plot, "Callirhoe" may be understood as the first historical novel; it was later imitated by Xenophon of Ephesus and Heliodorus of Emesa, among others.
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.
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.
Since the second half of the 20th century, inscriptions have been found on pottery in a variety of locations in China, such as Banpo near Xi'an, as well as on bone and bone marrows at Hualouzi, Chang'an County near Xi'an.
 These simple, often geometric, marks have been frequently compared to some of the earliest known Chinese characters appearing on the oracle bones, and some have taken them to mean that the history of Chinese writing extends back over six millennia.
 However, only isolated instances of these symbols have been found, and they show no indication of representing speech or of the non-pictorial processes that a writing system requires.
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.
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".
Factory model school and factory model education are terms describing both a style of learning and of educational facilities.
 The educational style, or pedagogy, first emerged in Europe in the late 18th Century and then in North America in the mid-19th century.
 The key characteristics of factory model education are top-down management, separation from the community, emphasis on management, centralized planning, standardization, outcomes designed to meet societal needs, and efficiency in producing results.
 They are frequently compared to the factory system of production.
 Factory model school facilities are typified by the school design of the mid to late 20th century - the modern or international style of architecture typified by efficiency and uniformity, often resembling a factory building.
 The system has been described as being "designed to create docile subjects and factory workers.”
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).
Os Magriços was the nickname of the Portugal national football team which finished third in the 1966 FIFA World Cup in England.
 It was based on the Benfica team that won two consecutive European Cups, in 1961 and 1962, and which included Mário Coluna, Eusébio, José Augusto, José Augusto Torres and António Simões.
 It was selected by Manuel da Luz Afonso and coached by Brazilian trainer Otto Glória.
 The nickname is derived from a 15th-century Portuguese chivalric legend - "The Twelve of England" (Portuguese: "Os Doze de Inglaterra").
 It was made famous by the poet Luís de Camões in his 1572 "Os Lusíadas".
 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.
 One of these Portuguese knights, Álvaro Gonçalves Coutinho, was nicknamed "O Magriço".
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.
