One of the treasures of The New York Public Library's Spencer Collection, The Medici Aesop is a 15th-century Florentine manuscript of Aesop's fables, traced to the library of Lorenzo de Medici's son Piero and illustrated with exquisite miniature paintings, among the loveliest in any Renaissance work. Its magnificently illustrated pages feature a rainbow of brilliant colors and elaborate decorations that dazzle today's reader as they once did the Medicis.
