# Bronze doors \(detail\) [View the canonical artwork record]() ## Artwork - Artist: [BONANNO DA PISA]() - Date: 1151-1200 - Technique: Bronze ## Commentary We know the names of many of the medieval master bronze-founders. The celebrated Bonanno da Pisa was the founder of the bronze doors of the Duomo at Pisa and those of the main entrance of Monreale cathedral. There is still the problem of how the tasks were distributed between sculptor and founder, unless they were one and the same person. ## Related artworks - [Bronze doors \(detail\)]() - [Bronze doors \(detail\)]() ## Attribution [Web Gallery of Art]()
