Round, or tondo, frames housing mirrors or devotional images were a popular type of domestic furnishing in Tuscany in the fifteenth and sixteenth centuries. Carved from a single piece of poplar and embellished with griffins and harpies, this example, which was made as a mirror frame, bears the coat of arms of the Cinuzzi family of Siena and is almost certainly of Sienese manufacture—it may have been designed by the sculptor Giovanni di Stefano, son of the famous painter Sassetta (see 1975.1.27). The present mirror is not original.
