The cassone ("large chest") was one of the trophy furnishings of rich merchants and aristocrats in Italian culture, from the Late Middle Ages onward.
At the end of the 15th century, a new classicising style arose, and early Renaissance cassoni of central and northern Italy were carved and partly gilded, and given classical décor, with panels flanked by fluted corner pilasters, under friezes and cornices, or with sculptural panels in high or low relief.
By the mid-sixteenth century Giorgio Vasari could remark on the old-fashioned cassoni with painted scenes, examples of which could be seen in the palazzi of Florentine families.
They were part of the immobili ("unmoveables"), perhaps even more than the removable glazed window casements, and might be left in place, even if the palazzo passed to another family.
In the east part of Emilia Romagna, the "cassone" term is also used to describe a local food, which is a round flat bread cooked on a special pan called "testo".
