Besides Bernardo, Andrea had a brother called Jacopo, who was engaged in sculpture, but with little profit; and in making on occasion for this Jacopo designs in relief and in clay, there came to him the wish to make something in marble and to see whether he remembered the principles of that art, wherein, as it has been said, he had worked in Pisa; and so, putting himself with more study to the test, he made progress therein in such a fashion that afterwards he made use of it with honour, as it will be told. Afterwards he devoted himself with all his energy to the study of architecture, thinking that at some time or another he would have to make use of it. Nor did his thought deceive him, seeing that in the year 1355, the Commune of Florence having bought some citizens' houses near their Palace (in order to have more space and to make a larger square, and also in order to make a place where the citizens could take shelter in rainy or wintry days, and carry on under cover such business as was transacted on the Ringhiera when bad weather did not hinder), they caused many designs to be made for the building of a magnificent and very large Loggia for this purpose near the Palace, and at the same time for the Mint where the money is struck. Among these designs, made by the best masters in the city, that of Orcagna being universally approved and accepted as greater, more beautiful, and more magnificent than all the others, by decree of the Signori and of the Commune there was begun under his direction the great Loggia of the square, on the foundations made in the time of the Duke of Athens, and it was carried on with squared stone very well put together, with much diligence. And what was something new in those times, the arches of the vaulting were made no longer quarter-acute, as it had been the custom up to that time, but they were turned in half-circles in a new and laudable method, which gave much grace and beauty to this great fabric, which was brought to completion in a short time under the direction of Andrea. And if there had been taken thought to put it beside S. Romolo and to turn the arches with the back to the north, which they did not do, perchance, in order to have it conveniently near to the gate of the Palace, it would have been as useful a building for the whole city as it is beautiful in workmanship; whereas, by reason of the great wind, in winter no one can stand there. In this Loggia, between the arches on the front wall, in some ornamental work by his own hand, Orcagna made seven marble figures in half-relief representing the seven Theological and Cardinal Virtues, as accompaniment to the whole work, so beautiful that they made him known for no less able as sculptor than as painter and architect; not to mention that he was in all his actions as pleasant, courteous, and lovable a man as was ever any man of his condition. And because he would never abandon the study of any one of his professions for that of another, while the Loggia was building he made a panel in distemper with many large figures, with little figures in the predella, for that chapel of the Strozzi wherein he had formerly made some works in fresco with his brother Bernardo; on which panel, it appearing to him that it could bear better testimony to his profession than the works wrought in fresco could do, he wrote his name with these words: ANNO DOMINI MCCCLVII, ANDREAS CIONIS DE FLORENTIA ME PINXIT.
