Pope Pius II in the context of "Flavio Biondo"

The Gutenberg Bible, also known as the 42-line Bible, the Mazarin Bible or the B42, was the earliest major book printed in Europe using mass-produced metal movable type. It marked the start of the "Gutenberg Revolution" and the age of printed books in the West. The book is valued and revered for its high aesthetic and artistic qualities and its historical significance.

The Gutenberg Bible is an edition of the Latin Vulgate printed in the 1450s by Johannes Gutenberg in Mainz (Holy Roman Empire), in present-day Germany. Out of either 158 or 180 copies that were originally printed, 49 survive in at least substantial portion, 21 of them in entirety; of these, the copy with the earliest visible print date is marked as 15 August 1456. They are thought to be among the world's most valuable books, although no complete copy has been sold since 1978. In March 1455, the future Pope Pius II wrote that he had seen pages from the Gutenberg Bible, displayed in Frankfurt to promote the edition.

Ladislaus V, more commonly known as Ladislaus the Posthumous (Hungarian: Utószülött László; Croatian: Ladislav Posmrtni; Czech: Ladislav Pohrobek; German: Ladislaus Postumus; 22 February 1440 – 23 November 1457), was Duke of Austria and King of Hungary, Croatia and Bohemia. He was the posthumous son of Albert of Habsburg with Elizabeth of Luxembourg. Albert had bequeathed all his realms to his future son on his deathbed, but only the estates of Austria accepted his last will. Fearing an Ottoman invasion, the majority of the Hungarian lords and prelates offered the crown to Vladislaus III of Poland. The Hussite noblemen and towns of Bohemia did not acknowledge the hereditary right of Albert's descendants to the throne, but also did not elect a new king.

After Ladislaus's birth, his mother seized the Holy Crown of Hungary and had Ladislaus crowned king in Székesfehérvár on 15 May 1440. However, the Diet of Hungary declared Ladislaus's coronation invalid and elected Vladislaus I as king. A civil war broke out which lasted for years. Elizabeth appointed her late husband's distant cousin, Albert VI as her child's guardian. However, as a representative of the interests of the Austrian and Hungarian estates, he could not defend himself against his older brother and rival, Frederick III, King of the Romans, who in turn took over his role as guardian of Ladislaus. Albert had to renounce his guardianship and in return received the mighty Hungarian border castle Forchtenstein, including a principality in the Hungarian-Styrian-Carinthian area. Ladislaus lived at Frederick's court (mainly in Wiener Neustadt), where Aeneas Silvius Piccolomini (later Pope Pius II) wrote a treatise on his upbringing.

Pinturicchio, or Pintoricchio (US: /ˌpɪntəˈriːkioʊ/, Italian: [pintuˈrikkjo]; born Bernardino di Betto; 1454–1513), also known as Benetto di Biagio or Sordicchio, was an Italian Renaissance painter. He acquired his nickname (meaning "little painter") because of his small stature and he used it to sign some of his artworks that he produced during the fifteenth and sixteenth centuries.

The Liber Pontificalis (Latin for 'pontifical book' or Book of the Popes) is a book of biographies of popes from Saint Peter until the 15th century. The original publication of the Liber Pontificalis stopped with Pope Adrian II (867–872) or Pope Stephen V (885–891), but it was later supplemented in a different style until Pope Eugene IV (1431–1447) and then Pope Pius II (1458–1464). Although quoted virtually uncritically from the 8th to 18th centuries, the Liber Pontificalis has undergone intense modern scholarly scrutiny. The work of the French priest Louis Duchesne (who compiled the major scholarly edition), and of others has highlighted some of the underlying redactional motivations of different sections, though such interests are so disparate and varied as to render improbable one populariser's claim that it is an "unofficial instrument of pontifical propaganda."

The title Liber Pontificalis goes back to the 12th century, although it only became current in the 15th century, and the canonical title of the work since the edition of Duchesne in the 19th century. In the earliest extant manuscripts it is referred to as Liber episcopalis in quo continentur acta beatorum pontificum Urbis Romae ('episcopal book in which are contained the acts of the blessed pontiffs of the city of Rome') and later the Gesta or Chronica pontificum.
