Siena Duomo: Clerestory


Detail of clerestory in the nave, with striped marble to match the pillars below. The cornice is decorated with busts of popes made in the workshop of Giovanni di Stefano beginning in 1495. Only four or five terracotta molds were used to make the busts, so many of them are identical. 13th century. Duomo, Siena, Italy.
