Let it be known to all that Filippo di Filippo, painter, has engaged to paint for Filippo di Matteo degl’ Strozzi, his chapel in Sta. Maria Novella, next to the high altar, under the following conditions: In the ceiling there are to be four figures, either Doctors, or Evangelists, or others, as the said Strozzi prefers, to be decorated in blue and gold as richly as can be; the remainder of the ceiling to be all of blue ultramarine of the finest, of the cost of at least 4 “fiorini larghi” the ounce, and the shafts and capitals are to be adorned with painting and gold, according to necessity. And on either side there are to be two stories [paintings] the subjects to be given by the said Filippo Strozzi; and the sides of the window, and the pillars, and the arch of the chapel inside and out, and the coats of arms, are to be ornamented as the said Filippo orders; and in every place where it be necessary such gold and ultramarine as is called for, shall be used, and every other colour shall be good and perfect. And the said Filippo di Filippo promises to the said Strozzi to paint it in fresco and to finish it with all the care and diligence he is capable of; and all with his own hand, especially the figures. And it is agreed that the said Filippo is to have for his work, with painting, colours, azure, scaffoldings, lime, wood and everything else, so that the said Strozzi shall have no other calls upon him, 300 fiorini di suggello[92] paid as follows: 35 fiorini now, when he begins the work, for the wood, lime, and other necessaries; the remainder, up to 100 fiorini, when he desires to go to Venice;[93] and the rest from time to time as he works, but so that 50, or at least 40, fiorini shall remain, which the said Strozzi promises to pay punctually when he has finished, which he promises to do by the 1st March, 1480....
