Clement VIII in the context of "Long Turkish War"

Federico Commandino (1509 – 5 September 1575) was an Italian humanist and mathematician.

Born in Urbino, he studied at Padua and then at Ferrara, where he received his doctorate in medicine under Antonio Musa Brassavola. He had numerous patrons throughout his life. Initially, aided by Grassi, the bishop of Viterbo, he then came under the patronage of Pope Clement VIII. In Urbino, he was sponsored by Guidobaldo II della Rovere, but then came to Rome with cardinal Ranuccio Farnese. In Rome, he was patronized by Cardinal Cervini, who served briefly as Pope. Lured back to Urbino by Francesco Maria II della Rovere. In Urbino, he putatively met John Dee, and corresponded with the scholars Conrad Dasypodius (il Dasipodio), Gerolamo Cardano, Francesco Maurolico, and Christopher Clavius.

Antonio Musa Brassavola (variously spelled Brasavola or Brasavoli; 16 January 1500 – 6 July 1555) was an Italian physician and one of the most famous of his time. He studied under Niccolò Leoniceno and Giovanni Manardo. He was the friend and physician of Ercole II, the duke of Este. He was also the consulting physician of Kings Francis I, Charles V, Henry VIII and Popes Paul III, Leo X, Clement VIII and Julius III. He performed the first successful tracheotomy, and published an account of it in 1546. He was the chair of philosophy in Ferrara and also studied botany and medicine. A genus of orchid, called Brassavola, is named after him.

Torquato Tasso (/ˈtæsoʊ/ TASS-oh, also US: /ˈtɑːsoʊ/ TAH-soh, Italian: [torˈkwaːto ˈtasso]; 11 March 1544 – 25 April 1595) was an Italian poet of the 16th century, known for his 1581 poem Gerusalemme liberata (Jerusalem Delivered), in which he depicts a highly imaginative version of the combats between Christians and Muslims at the end of the First Crusade, during the Siege of Jerusalem of 1099.

Tasso had a mental illness and died a few days before he was to be crowned on the Capitoline Hill as the king of poets by Pope Clement VIII. His work was widely translated and adapted, and until the beginning of the 20th century, he remained one of the most widely read poets in Europe.
