Giorgio Vasari (vəˈsɑːri, also US-ˈzɑːr-,_vɑːˈzɑːri, ˈdʒordʒo vaˈzaːri; 30 July 1511 – 27 June 1574) was an Italian Renaissance painter and architect, who is best known for his work The Lives of the Most Excellent Painters, Sculptors, and Architects, considered the ideological foundation of all art-historical writing, and still much cited in modern biographies of the many Italian Renaissance artists he covers, including Leonardo da Vinci and Michelangelo, although he is now regarded as including many factual errors, especially when covering artists from before he was born.
Giorgio was a Mannerist painter who was highly regarded both as a painter and architect in his day, but rather less so in later centuries. He was effectively what would now be called the minister of Culture to the Medici court in Florence, and the Lives promoted, with enduring success, the idea of Florentine superiority in the visual arts.
Vasari designed the Tomb of Michelangelo, his hero, in the Basilica of Santa Croce, Florence that was completed in 1578. Based on Vasari's text in print about Giotto's new manner of painting as a rinascita (rebirth), author Jules Michelet in his Histoire de France (1835) suggested the adoption of Vasari's concept, using the term Renaissance (rebirth, in French) to distinguish the cultural change. The term was adopted thereafter in historiography and is still in use today.
Vasari was born prematurely on 30 July 1511 in Arezzo, Tuscany. Recommended at an early age by his cousin Luca Signorelli, he became a pupil of Guglielmo da Marsiglia, a skillful painter of stained glass. Sent to Florence at the age of sixteen by Cardinal Silvio Passerini, he joined the circle of Andrea del Sarto and his pupils, Rosso Fiorentino and Jacopo Pontormo, where his humanist education was encouraged. He was befriended by Michelangelo, whose painting style would influence his own.
Vasari enjoyed high repute during his lifetime and amassed a considerable fortune. He married Niccolosa Bacci, a member of one of the richest and most prominent families of Arezzo.
