Antonio di Tuccio Manetti (6 July 1423 – May 26, 1497) 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 (also known as Arte della Seta), one of the seven Arti Maggiori guilds of Florence. Born to a family of silk merchants, Manetti not only received an excellent education but was confronted with ample free time in which he was able to cultivate his many interests, which included mathematics, geometry, astronomy and philosophy. Private life From the Parte Guelfa records, it becomes apparent that Manetti had 4 brothers, named Nezzo di Tuccio Marabottino, Lorenzo di Tuccio Marabottino, Marabottino di Tuccio di Marabottino and Benedetto di Tuccio Marabottino. Also present in the records is what seems like his grandson, Benedetto di Tuccio di Marabottino, which would indicate a marriage at some point in his life. Much of what is known about Manetti's private life stems from the works of Milanesi; He writes that Manetti was named a Bonomini in 1470. He became a member of the Balìa a year later and in 1475 he became the Vicario of the Valdarno di Sopra. In 1476 he was one of the Priori and in 1481 he was Vicario of Valdinievole. In 1485 he was Gonfaloniere di Giustizia, and after that he served as Podestà of Colle di Val d'Elsa. He was among the civis et architectus working on the facade of S. Maria del Fiore in January 1491. His presence in the executive branch of the Florentinian government suggests that Manetti was well connected with influential thinkers of his time. Recent documents also suggest that during 1466 Manetti was part of the operai of the Spedale degli Innocenti.
