Another piece of work with which these months were occupied was the design of "Fortune," for one of the spaces on the pavement of Siena Cathedral. The pavement of Siena is a remarkable production differing from any other work of art in existence; a mixture of _intaglio_ or engraving on stone, varied by _intarsia_ or inlay of marbles. The work had been long in progress, and designs for the various scenes had been furnished by artists from 1369 onwards. One painter of Umbrian extraction, Matteo di Giovanni, had already supplied his favourite subject of the "Murder of the Innocents." Pintoricchio's design is reproduced in the fourth space as we walk up the nave. It is an allegory of the excellence of Wisdom and the folly of Pleasure. The sky is of pure black marble, the island of grey, the fields, the sea, and the figures of pale marble, engraved with dark lines and inlaying. In the middle sits Wisdom, crowned with flowers, and bearing a palm branch and a book. On one hand Socrates receives from her the palm; on the other a philosopher casts a collection of trinkets and baubles into the sea. On a lower plane, a company of pilgrims, the foremost of whom is presumably a portrait, climbs a path set with stones and thistles, and beset with serpents, lizards, a tortoise, and a snail. One sits down and falls asleep, another turns to shake his fist at Pleasure, a fair, naked woman, holding a cornucopia of flowers, and spreading a sail to catch the passing breeze. One foot rests on the ball of Fortune, as she steps off the shore on to a rudderless boat, and a young man, the last in the procession, casts back a wistful glance in her direction. This design is significant as showing what the painter could do when colour was denied him. The balance of the groups is kept with great art, and the outline of Pleasure is full of grace and daring. The general shape of the reliefs, in light against dark and as furnishing a pattern, is treated with perfect success.

With the spring Pintoricchio again began the painting of the Library frescoes, but he had not proceeded far when Andrea Piccolomini, one of the late Pope's executors, died. That this must have necessitated a further re-adjustment, and meant another period of delay, we may gather from finding that, in June 1505, Pintoricchio was once more in Rome. The ten months that followed must have been very busy ones, and no doubt the master, after the repeated hitches under his new patrons, was relieved to find himself once more working for those earlier ones in whose service he had always had good fortune.
