Antonio Manetti
A Florentine Renaissance man who used geometry to map Dante's Hell and penned a famous tale of a clever, cruel practical joke.

Biography
Living in the shadow of the Florentine giants, Antonio Manetti was a quintessential Renaissance scholar—a mathematician, astronomer, and architect who applied rigorous logic to both art and mystery. He is best remembered for a peculiar and fascinating project: using the text of Dante's 'Inferno' as a blueprint, he calculated the precise dimensions, location, and architecture of Hell itself. His findings, published by friends, treated Dante's poetry as a cosmological puzzle to be solved with Euclidean geometry. Beyond this infernal cartography, Manetti moved in the circles of Brunelleschi and Alberti, contributing to the city's architectural works. His literary legacy rests on 'The Fat Woodworker,' a sharp, novelistic short story that recounts an elaborate hoax orchestrated by Brunelleschi to humble a boastful carpenter. In this tale, as in his Dante studies, Manetti displayed a distinctly Florentine blend of intellectual curiosity, wit, and a taste for the ingeniously contrived.

Key Achievements
- Conducted groundbreaking geometric and topographic research to determine the size, structure, and earthly location of Dante's Inferno.
- Wrote 'The Fat Woodworker' (Il Grasso Legnaiuolo), a celebrated early Renaissance novella about a practical joke by Brunelleschi.
- Served as a consultant and mathematician on significant architectural projects in 15th-century Florence.

Did You Know?
Manetti claimed, based on his calculations, that the entrance to Dante's Hell was a conical pit located under Jerusalem.
He was a close friend and biographer of the architect Filippo Brunelleschi.
His work on Dante attempted to reconcile medieval theology with the new Renaissance spirit of scientific measurement.
He also wrote a biography of the poet Guido Cavalcanti and studied ancient Roman architecture.
“Measure the circles of Hell; geometry is the key to the poet's vision.”
