A good many of his works in Siena shew traces of, and even whole figures by other hands; having been finished by Vanni, and Ventura Salimbeni, or by other artists, either of his own or of different schools. Ilario Casolani, his son, by a daughter of Rustici, finished the Assumption for the Church of S. Francis; and afterwards went to Rome, where he was "noticed by Cav. Pomaranci, out of respect to his father," says Mancini, as of a thing he knew, and adds, that Pomaranci had good hopes of him. Baglione and Pio called him Cristoforo, a name he, perhaps, received along with several others at baptism; and which probably the Sienese artist thought more becoming at Rome than Ilario, since he is named Cristoforo, by Roncalli. Under Pomaranci he became a proficient in his style in fresco, and imitated it particularly at Madonna de' Monti, in some pictures from the history of the Virgin, and in an Ascension on the ceiling; the best work, perhaps, produced in the short course of his life. Titi uniformly names him Cristoforo Consolano; but a consideration of the anecdotes of Mancini and Baglione leads us to convert it into Casolano. A Resurrection of Lazarus, begun by Alessandro for the church of S. Francis, was finished by Vincenzio Rustici; who was probably his scholar and his kinsman, and who is the least celebrated among this family of painters. One of his pictures, intended for Santuccio, was finished by Sebastiano Folli. The frescos of this artist are more numerous at Siena than his oil pictures: the ornamental parts of them are superior to his figures, in which he inclined to mannerism; his compartments are beautiful, his architecture finely conducted, his imitations of stucco deceive the eye, and he was expert in foreshortening what was to be seen from below. In 1608 he painted the frescos of S. Sebastian, in competition with various artists, and in this trial of skill he only yields to Rutilio Manetti. In the Guide of the Cav. Pecci I find mention made of designs of Casolani, executed in fresco by Stefano Volpi, whose name not unfrequently occurs in that work, and who was probably a scholar of that excellent artist.
