Beneath the cycles of "The Life of Moses" and "The Life of Christ", the lower level of the walls is decorated with frescoed hangings in silver and gold. Above the narrative frescos, the upper tier is divided into two zones. At the lower level of the windows is a "Gallery of Popes" painted at the same time as the "Lives". Around the arched tops of the windows are areas known as the "lunettes" which contain the "Ancestors of Christ", painted by Michelangelo as part of the scheme for the ceiling.
