Arnolfo di Cambio
The Spanish Chapel was decorated from 1365 to 1367 by Andrea di Bonaiuto, also known as Andrea da Firenze. The large fresco on the right wall depicts an "Allegory of the Active and Triumphant Church and of the Dominican order". It is especially interesting because in the background it shows a large pink building that some think may provide some insight into the original designs for Florence Cathedral by Arnolfo di Cambio (before Brunelleschi's dome was built). However, such an interpretation is fantasy since the Duomo was never intended to be pink, nor to have the bell tower at the rear. This fresco also contains portraits of pope Benedict IX, cardinal Friar Niccolò Albertini, count Guido di Poppi, Arnolfo di Cambio and the poet Petrarch.
