Alberti, between 1428 and 1443, has written, in Latin and Italian, love poems and dialogues, a Latin comedy, fables, and treatises on agriculture, the care of horses, law, marriage, sculpture, and virtue.

Della tranquilita dell' animo (“On Peace of Mind”) written in 1442, is among the finest of these.

Nineteen-year-old painter Andrea del Castagno has won recognition in Florence for a representation, on the facade of the Palazzo del Podesta, of hanged men who had been traitors to Florence during the Battle of Anghiari in 1440.

This work earns him the sobriquet “Andreino degli Impicatti" ( "Little Andrew of the Hanged Men" ).

Upon his return from Venice in 1443, Castagno works at the Duomo, where he supplies the cartoon for the stained-glass window depicting the deposition of Christ. (Although little is known of Castagno's earliest training, his figure drawing, characterized by a monumental, sculptural grandeur even in his earliest works, indicates that he is strongly affected by the works of Masaccio. Domenico Veneziano, Donatello, Ghiberti, and Piero della Francesca are also influential in his development.)

Florentine sculptor and architect Michelozzo di Bartolommeo, like Brunelleschi, has received many commissions from Cosimo de' Medici, including those for the library of the Convent of San Marco, constructed between 1436 and 1443.
