Copy of a panel of the first set of reliefs decorating the base of Giotto's Campanile. The panel shows a medieval ambulatorium or medical dispensary: several women are waiting to hand the doctor a urine glass with the urine to be analyzed. The original bas-relief, now housed in the Museo dell'Opera del Duomo, was sculpted between 1334 and 1336 by Andrea Pisano and his assistant(s), or by his son Nino. The work was long attributed to Andrea Pisano.
