We may here again refer to Ruscelli’s directions for globe construction,[303] to which he added certain suggestions for globe adornment, that they might appeal to princes and nobles. “Globes of copper, bronze or silver,” he says, “such as princes would desire to possess, to be fine, durable and rare should be plated, that is, the circles, the letters, the outlines of the countries should first be engraved and then there should be added gold or silver plating.” “A generous prince,” he adds, “could have them made in Asimino or Tausia style, as they say, that is, have the copper surface engraved, and the grooves filled with silver or gold thread. By forcing this in the work can be made very strong.” He states in one of his chapters that globes so constructed are usually small, but he adds that he had seen globes three and a half palms in diameter, such as that sent to him by Zurelio Porcelaga. Of this last he speaks in words of praise, passing on to refer to two large ones then under construction in Venice. “One of these,” he says, “is of copper being made by Giulio Sanuto, which it is hoped will be one of the best as one of the most beautiful of any constructed up to the present time.” The implication seems to be, from the words of Ruscelli, that at least some part of the printing was to be made directly on the surface of the sphere. Further information given by Ruscelli touching Sanuto and Gonzaga in this connection is here of interest. He states “besides the fact that Giulio Sanuto is very skilful in drawing and engraving, especially in geographical maps of the world and its parts, he is, in this task, being aided by Livio Sanuto,[304] a Venetian nobleman, his brother, among whose many good qualities he possesses to a degree above the ordinary, are his attainments in the profession of geography. Both are giving so much attention to this globe that it is expected, in both matter and form, it will be perfect. Another globe three arm’s length in diameter has, since last year, been begun by Curtio Gonzaga, which he intends shall contain all of those things that Taisnero has included in his globe as well as many other things that the said gentleman intends to add, hoping to make one of the most beautiful and perfect spheres to be seen for many years to come. This can easily be believed, for he will do everything himself, and as the greater diligence will thus be exercised we will have all of the advantages of his great knowledge of geography, to which subject as ever, he is giving all of his attention, and the advantage of his great skill in lettering and designing.”[305]
