Baccio Pontelli

Baccio Pontelli (c. 1449 – c. 1494) was an Italian architect and worker in wood inlays, who designed the Sistine Chapel in Vatican City.

[1] He trained in artistic woodwork such as marquetry in the workshop of Giuliano and Benedetto da Maiano in Florence, and was influenced by Francesco di Giorgio Martini during a trip to Urbino (1480–1482), where he worked on the Studiolo of Duke Federico de Montefeltro, in the Palazzo Ducale, Urbino.

The tendency of Giorgio Vasari to attribute most Papal building commissions in the period to his fellow-Florentine has rather confused matters.

[2] That said, his projects included: Santa Aurea and fortifications in Ostia; the Ponte Sisto in Rome; the hospital of Santo Spirito in Sassia; the church Sant'Agostino; the facade of Santa Maria del Popolo; San Pietro in Vincoli; Santi Apostoli and design for the Sistine Chapel.

In the last years of his life he worked in the Marche region on the military fortresses of Acquaviva Picena Jesi, Osimo and Senigallia.
