Leonardo di ser Piero da Vinci was an Italian polymath of the High Renaissance who was active as a painter, draughtsman, engineer, scientist, theorist, sculptor, and architect. While his fame initially rested on his achievements as a painter, he also became known for his notebooks, in which he made drawings and notes on a variety of subjects, including anatomy, astronomy, botany, cartography, painting, and paleontology. Leonardo is widely regarded to have been a genius who epitomized the Renaissance humanist ideal, and his collective works comprise a contribution to later generations of artists matched only by that of his younger contemporary Michelangelo.
Fra. Luca Bartolomeo de Pacioli was an Italian mathematician, Franciscan friar, collaborator with Leonardo da Vinci, and an early contributor to the field now known as accounting.

He was also called Luca di Borgo after his birthplace, Borgo Sansepolcro, Tuscany.
The Biblioteca Ambrosiana is a historic library in Milan, Italy, also housing the Pinacoteca Ambrosiana, the Ambrosian art gallery. Named after Ambrose, the patron saint of Milan, it was founded in 1609 by Cardinal Federico Borromeo, whose agents scoured Western Europe and even Greece and Syria for books and manuscripts. Some major acquisitions of complete libraries were the manuscripts of the Benedictine monastery of Bobbio (1606) and the library of the Paduan Vincenzo Pinelli, whose more than 800 manuscripts filled 70 cases when they were sent to Milan and included the famous Iliad, the Ilias Picta.
