Cenacolo di Sant'Apollonia

This guide to the Cenacolo di Sant'Apollonia in Florence follows a Last Supper fresco that almost no man was allowed to see for nearly four hundred years, painted in 1447 by Andrea del Castagno inside a cloistered Benedictine convent sealed off from the city since 1339. You'll hear why the chronicler Giorgio Vasari, who catalogued nearly every great Florentine painter, never once mentioned it, and what restorers found hidden beneath the fresco when they detached it from the wall in 1953. Look closely at how Castagno set Judas apart from the other apostles at the table.
