KANTER: Two of the most easily overlooked objects in this room are the two round mirrors exhibited to the side of either of the doorways. These are fifteenth-century mirror frames, and, as you can see, the glass in each of them is convex, a peculiarity of fifteenth-century mirrors that we still have no idea how to explain.

AMORY: The mirror to the left of the Venetian glass display still contains its original glass. The reflective surface in the other mirror is a modern replacement, imitating the original convex glass. Laurence Kanter.

KANTER: Both mirrors were designed by architects and made by prominent sculptors. They both include coats of arms. In one case, we were able to identify that as the Cinuzzi family of Siena. And we know the architect who redid their palace and therefore we can attribute the mirror frame with some certainty to a particular maker. It is very unusual to be able to identify frames of any kind from the fifteenth-century by who made them. They're very rare objects to survive, and even rarer is documentation that might go along with them. The Lehman Collection overall has perhaps the world's most distinguished collection of fifteenth- and sixteenth-century frames. These two examples are particularly fine and interesting ones in the context of a domestic interior.

AMORY: Other frames from this period are on view elsewhere in the Lehman Wing.
