Meanwhile Sebastiano della Seta, the Warden of Works of the Duomo, having heard from Cervelliera of the qualities and abilities of Domenico, and being desirous to finish the work so long delayed by Giovanni Antonio Sogliani, allotted two of the pictures for that recess to Domenico, to the end that he might execute them at Siena and send them finished to Pisa; and so it was done. In one is Moses, who, having found that the people had sacrificed to the Golden Calf, is breaking the Tables; and in this Domenico painted some nudes that are figures of great beauty. In the other is the same Moses, with the earth opening and swallowing up a part of the people; and in this, also, are some nudes killed by flaming thunderbolts, which are marvellous. These pictures, when taken to Pisa, led to Domenico painting four pictures for the front of that recess--namely, two on each side--of the four Evangelists, which were four very beautiful figures. Whereupon Sebastiano della Seta, who saw that he had been served quickly and well, commissioned Domenico, after these pictures, to paint the altar-piece of one of the chapels in the Duomo, Sogliani having by that time painted four. Settling in Pisa, therefore, Domenico painted in that altar-piece Our Lady in the sky with the Child in her arms, upon some clouds supported by some little Angels, with many Saints both male and female below, all executed passing well, but yet not with that perfection which marked the pictures described above. But he, excusing himself for this to many of his friends, and particularly on one occasion to Giorgio Vasari, said that since he was away from the air of Siena and from certain comforts of his own, he did not seem to be able to do anything. Having therefore returned home, determined that he would never again go away to work elsewhere, he painted for the Nuns of S. Paolo, near S. Marco, an altar-piece in oils of the Nativity of Our Lady, with some nurses, and S. Anne in a bed that is foreshortened and represented as standing within a door; and in a dark shadow is a woman who is drying clothes, without any other light but that which comes from the blaze of the fire. In the predella, which is full of charm, are three scenes in distemper--the Presentation of the Virgin at the Temple, her Marriage, and the Adoration of the Magi. In the Mercanzia, a tribunal in that city, the officials have a little altar-piece which they say was painted by Domenico when he was young; it is very beautiful, and it contains in the centre a S. Paul seated, and on one side his Conversion, in little figures, and on the other the scene of his Beheading.
