Lorenzo Ghiberti (; 1378 – 1 December 1455), born Lorenzo di Bartolo, was a Florentine Italian artist of the  Early Renaissance best known as the creator of the bronze doors of the Florence Baptistery, called by Michelangelo the Gates of Paradise. Trained as a goldsmith and sculptor, he established an important workshop for sculpture in metal. His book of Commentari contains important writing on art, as well as what may be the earliest surviving autobiography by any artist.
