Luigi Baccio del Bianco or Baccio del Bianco (31 October 1604 – July 1657) was an Italian architect, engineer, scenic designer and painter. He was born at Florence and studied painting under Giovanni Bilivert from 1612 to 1620. Baccio's work and letters also show the influence exerted on the painter by Vincenzio Bocaccio of Rome, who came to Florence, delegated as one of the best students of the architect and painter Lodovico Cigoli. He also apprenticed under Giulio Parigi.
In 1620 he visited Germany; on his return he decorated several houses, and painted for churches and theatres. In 1622 he went to Vienna to assist Giovanni de Galliano Pieroni (1586–1654), and later the same year both went on to Prague, where he performed extensive work in fresco, some with help of assistants. He did not stay long, as there is evidence he lived in Milan shortly thereafter and was back in Florence in 1625. In 1651 he went to Spain to paint stage designs for theatres. He died at Madrid in 1657. In Spain he was known as Bartolomeo del Blanco, since Baccio is an Italian diminutive for Bartolommeo or Bartolomeo, while Bianco and Blanco are Italian-Spanish equivalents of "white". Accordingly, he shows up as such in certain sources.
