This towering figure of the Early Renaissance was a sculptor (the Sacrifice of Isaac for the Baptistery, now in the Bargello; the Crucifix in the Gondi Chapel in Santa Maria Novella) and architect in Florence. Among his masterpieces we may admire today the dome over Santa Maria del Fiore, the Hospital of the Innocenti, the Church of Santo Spirito, the Church and Sacristy of San Lorenzo, and the Pazzi Chapel.
Also attributed monuments to him are buildings scattered among the towns of Signa, Malmantile and Vicopisano, which could constitute the interesting stages of an itinerary that is only apparently a "minor" one.
Brunelleschi exerted notable influence on Leonardo, who re-elaborated his construction site machines in the Codex Atlanticus.
Thanks to a folio of the Leonardesque school (now in the Uffizi, Cabinet of Drawings and Prints) the projects for a river boat called the "Badalone" and for a self-propelled wagon invented by Brunelleschi, of whom no autograph drawings have hitherto been found, are known to us. Lastly, Brunelleschi was indirectly Leonardo's master in perspective and probably, through their mutual friend Paolo dal Pozzo Toscanelli, in his mathematical concepts.
