The Bamboccianti were genre painters active in Rome from about 1625 until the end of the seventeenth century. Most were Dutch and Flemish artists who brought existing traditions of depicting peasant subjects from sixteenth-century Netherlandish art with them to Italy, and generally created small cabinet paintings or etchings of the everyday life of the lower classes in Rome and its countryside.
Typical subjects include food and beverage sellers, farmers and milkmaids at work, soldiers at rest and play, and beggars, or, as Salvator Rosa lamented in the mid-seventeenth century, "rogues, cheats, pickpockets, bands of drunks and gluttons, scabby tobacconists, barbers, and other 'sordid' subjects." Despite their lowly subject matter, the works themselves sold for high prices to esteemed collectors.
