The Biblioteca Laurentiana of Florence possesses four small armillary spheres, bearing neither date nor author legends.[328] The larger of these has a diameter of about 32 cm., is of brass, and rests upon an artistic support composed of a group of bronze satyrs. The other three, by reason of their close resemblance, appear to be the work of the same artist. Each has a diameter of about 23 cm. and a base of brass on which stands a small bronze statue, which bears on its shoulders a globe. This globe supports the several circles composing the armillary sphere. The supporting statue in one of these is clad and is represented as wearing sandals on the feet, supposedly representing the mythical Atlas. In another of these the statue is that of a man resting on the right knee with the left hand uplifted, while in the third the statue is that of a woman resting upon the left knee, having the right hand uplifted. These globes are reported as not being in good condition, but each exhibits artistic merit of a high order. There is likewise to be found in the Biblioteca Nationale of Florence a small celestial globe of bronze, and a celestial and terrestrial globe of silver. These globes are neither signed nor dated but are thought to belong to the period now under consideration. The bronze globe has the constellations represented in relief. It is exceedingly small, having a diameter of about 10 cm. The silver globes have diameters about half the preceding, or about 4.5 cm. They are furnished with horizon and meridian circles, and have mountings which clearly are modern. The several constellations represented on the celestial globe are exceedingly well done, as are all of the decorative figures appearing on the terrestrial globe. Geographical names are necessarily few because of the size of the globe. Attention has been called to the references which Ruscelli makes in his ‘Geografia’ to globe construction.[329] Notice may likewise here be called to a similar reference, though much more brief, made by Francesco Maurolico, a native of Messina, and often referred to as the new Archimedes, because of his great fame acquired in the field of mathematics and astronomy. In his work, published in the year 1575,[330] he devoted part of one chapter to the subject “De sphaera solida,” describing the construction of a celestial globe, and the use of the same. We have no evidence that he was ever engaged in the construction of such instruments as aids in the study of his science. Lastly, in this chapter, mention may be made of the work of Mario Cartaro. It appears that with his work that of the Italian globe makers of the century practically came to a close; the names of but two or three appear in the last quarter.
