Cellini's method of forming a silver vase was on this wise. The original plate of silver had to be red hot, "not too red, for then it would crack,--but sufficient to burn certain little grains thrown on to it." It was then adjusted to the stake, and struck with the hammer, towards the centre, until by degrees it began to take convex form. Then, keeping the central point always in view by means of compasses, from that point he struck "a series of concentric circles about half a finger apart from each other," and with a hammer, beginning at the centre, struck so that the "movement of the hammer shall be in the form of a spiral, and follow the concentric circles." It was important to keep the form very even all round. Then the vase had to be hammered from within, "till it was equally bellied all round," and after that, the neck was formed by the same method. Then, to ornament the vase, it was filled with pitch, and the design traced on the outside. When it was necessary to beat up the ornament from within, the vase was cleared out, and inverted upon the point of a long "snarling-iron," fastened in an anvil stock, and beaten so that the point should indent from within. The vase would often have to be filled with pitch and emptied in this manner several times in the course of its construction. Benvenuto Cellini was one of the greatest art personalities of all time. The quaintness of the aesthetic temperament is nowhere found better epitomized than in his life and writings. But as a producer of artistic things, he is a great disappointment. Too versatile to be a supreme specialist, he is far more interesting as a man and craftsman than as a designer. Technical skill he had in unique abundance. And another faculty, for which he does not always receive due credit, is his gift for imparting his knowledge. His Treatises, containing valuable information as to methods of work, are less familiar to most readers than his fascinating biography. These Treatises, or directions to craftsmen, are full of the spice and charm which characterize his other work. One cannot proceed from a consideration of the bolder metal work to a study of the dainty art of the goldsmith without a glance at Benvenuto Cellini. The introduction to the Treatises has a naive opening: "What first prompted me to write was the knowledge of how fond people are of hearing anything new." This, and other reasons, induced him to "write about those loveliest secrets and wondrous methods of the great art of goldsmithing." Francis I. indeed thought highly of Cellini. Upon viewing one of his works, his Majesty raised his hands, and exclaimed to the Mareschal de France, "I command you to give the first good fat abbey that falls vacant to our Benvenuto, for I do not want my kingdom to be deprived of his like."
