In the chapel at the end we find Donatello's wooden crucifix which led to that friendly rivalry on the part of Brunelleschi, the story of which is one of the best in all Vasari.

Donatello, having finished this wooden crucifix, and being unusually satisfied with it, asked Brunelleschi's opinion, confidently expecting praise.

But Brunelleschi, who was sufficiently close a friend to say what he thought, replied that the type was too rough and common: it was not Christ but a peasant.

Christ, of course, was a peasant; but by peasant Brunelleschi meant a stupid, dull man.

Donatello, chagrined, had recourse to what has always been a popular retort to critics, and challenged him to make a better.
