Grosso also always insisted upon something in advance and payment on delivery, and pleasantly described his workshop as being the Sign of the Burning Books,--since if his books were burnt how could he enter a debt?
This rule earned for him from Lorenzo the nickname of "Il Caparra" (earnest money).

Another of Grosso's eccentricities was to refuse to work for Jews.
Within the palace, up stairs, is the little chapel which Gozzoli made so gay and fascinating that it is probably the very gem among the private chapels of the world.

Here not only did the Medici perform their devotions--Lorenzo's corner seat is still shown, and anyone may sit in it--but their splendour and taste are reflected on the walls.

Cosimo, as we shall see when we reach S.Marco, invited Fra Angelico to paint upon the walls of that convent sweet and simple frescoes to the glory of God.

Piero employed Fra Angelico's pupil, Benozzo Gozzoli to decorate this chapel.
In the year 1439, as chapter II related, through the instrumentality of Cosimo a great episcopal Council was held at Florence, at which John Palaeologus, Emperor of the East, met Pope Eugenius IV.
