Andrea Tafi and Apollonio the Greek, then, in order to cover this tribune with mosaics, made therein a number of compartments, which, narrow at the top beside the lantern, went on widening as far as the level of the cornice below; and they divided the upper part into circles of various scenes. In the first are all the ministers and executors of the Divine Will, namely, the Angels, the Archangels, the Cherubim, the Seraphim, the Powers, the Thrones, and the Dominions. In the second row, also in mosaic, and after the Greek manner, are the principal works done by God, from the creation of light down to the Flood. In the circle that is below these, which goes on widening with the eight sides of that tribune, are all the acts of Joseph and of his twelve brethren. Below these, then, there follow as many other spaces of the same size that circle in like manner onward, wherein there is the life of Jesus Christ, also in mosaic, from the time when He was conceived in Mary's womb up to the Ascension into Heaven. Then, resuming the same order, under the three friezes there is the life of S. John the Baptist, beginning with the appearing of the Angel to Zacharias the priest, up to his beheading and to the burial that his disciples gave him. All these works, being rude, without design and without art, I do not absolutely praise; but of a truth, having regard to the method of working of that age and to the imperfection that the art of painting then showed, not to mention that the work is solid and that the pieces of the mosaic are very well put together, the end of this work is much better--or to speak more exactly, less bad--than is the beginning, although the whole, with respect to the work of to-day, moves us rather to laughter than to pleasure or marvel. Finally, over the side of the principal chapel in the said tribune, Andrea made by himself and without the help of Apollonio, to his own great credit, the Christ that is still seen there to-day, seven braccia high. Becoming famous for these works throughout all Italy, and being reputed in his own country as excellent, he well deserved to be largely honoured and rewarded. It was truly very great good-fortune, that of Andrea, to be born at a time when, all work being rudely done, there was great esteem even for that which deserved to be esteemed very little, or rather not at all. This same thing befell Fra Jacopo da Turrita, of the Order of S. Francis, seeing that, having made the works in mosaic that are in the recess behind the altar of the said S. Giovanni, notwithstanding that they were little worthy of praise he was remunerated for them with extraordinary rewards, and afterwards, as an excellent master, summoned to Rome, where he wrought certain things in the chapel of the high-altar of S. Giovanni Laterano, and in that of S. Maria Maggiore. Next, being summoned to Pisa, he made the Evangelists in the principal apse of the Duomo, with other works that are there,
