Then it recites the terms suggested by the Duke of Urbino in his letter of March 6, 1542, according to which three of the statues of the tomb may be assigned to capable craftsmen, while the other three, including the Moses, will have to be finished by Michelangelo himself.

Raffaello da Montelupo has already undertaken the Madonna and Child, a Prophet, and a Sibyl.

Giovanni de' Marchese and Francesco da Urbino are at work upon the architecture.

It remains for Michelangelo to furnish the Moses and two Captives, all three of which are nearly completed.

The Captives, however, were designed for a much larger monument, and will not suit the present scheme.
Accordingly, he has blocked out two other figures, representing the Active and Contemplative Life.
