Antonio Manetti, Italian mathematician and architect (died 1497)

Antonio di Tuccio Manetti was an Italian mathematician and architect from Florence. He is particularly noted for his investigations into the site, shape and size of Dante's Inferno. Although Manetti never himself published his research regarding the topic, the earliest Renaissance Florentine editors of the poem, Cristoforo Landino and Girolamo Benivieni, reported the results of his researches in their respective editions of the Divine Comedy. Manetti is also famous for his short story, The Fat Woodworker, which recounts a cruel practical joke devised by Brunelleschi. Furthermore, his supposed authorship of the biography of Filippo Brunelleschi has been widely discussed and analyzed. Manetti was further a member of the Arte di Por Santa Maria, one of the seven Arti Maggiori guilds of Florence.
