Vatican and Araceli Temple possess some of his works; at Siena he painted, in ten pictures, the history of Pio II. and added one of Pio III. his employer, and these, with what he left in the Dome of Spello, are the best of his labours. Of at more independent and grander spirit was Andrea Luigi, of Assisi, surnamed L'Ingegno, the Genius. He assisted Pietro in the Change-hall at Perugia, and there and in his Prophets and Sibyls at Assisi, aggrandized and mellowed the style of his master to a degree, which led Sandrart, with others, to ascribe the latter work to Raphael; but blindness checked his career in the bloom of life, and left the art to Raphael without a rival. Domenico di Paris Alfani added, likewise, some improvements to the style of Pietro. His name was nearly sunk in that of his son or brother Orazio, and time and dates alone have re-asserted its right to some excellent works long adjudged to the other; and which, were it not for an insipid sweetness of tone bordering on that of Baroccio, seem to have been inspired by the principles of Raphael. Of Pietro's many ultramontane pupils, Giovanni Spagnuolo, a Spaniard, called Lo Spagna, who settled at Spoleto, is considered by Vasari as the most eminent. But all these names united confer less celebrity on Pietro, than the felicity of having reared the powers of Raffaello Sanzio, if not the founder, the great establisher of the Roman School. Raffaello Sanzio, born at Urbino on Holy Friday, April 1483, was the son of Giovanni Sanzio, named among the contemporaries and occasional helpers of Pietro, in whose school, after having imparted the first rudiments of Art to his son, conscious of his own inferiority, he had the modesty to place him. Here his progress was so rapid that he soon rendered himself completely master of Vannucci's style, soon became his favourite pupil, soon his co-adjutor, and in a short period more than his competitor: for though the pictures which he painted at Cività di Castello and Perugia, and are so amorously dwelt on by Lanzi, still betray in composition, design, and colour, the principles of the master, they exhibit symptoms of that expression, that beauty, those simple graces, that refinement and precision of finish, which not only had remained unknown to Pietro, but in their purity were never attained by any subsequent artist.--Some of these are perceivable already, if scantily, in the Procession to Golgotha, preceded by horsemen and attended by the Madonna and her female train; and still less perceptibly in one of its predelle which exhibits the Saviour held extended by his Mother, Magdalen and John: they cannot be mistaken in the predelle which represents him among the sleeping disciples praying in the garden,--performances of his puerility, and most probably before he left the school of Pietro.
