indicated with appropriate accompanying inscriptions. Two pairs of Praetorius’ globes are now known, one pair in the Mathematical Salon of Dresden (Fig. 68),[312] and the other in the Germanisches National Museum of Nürnberg. These globes are of brass, each having a diameter of 28 cm.; each is supplied with meridian, horizon, and hour circles and rests on a tripod base. They are richly engraved pieces, the terrestrial example being remarkably well preserved, the celestial being slightly injured, through rubbing which has removed parts of certain figures of the constellations. [Illustration: Fig. 68. Globe of Johannes Praetorius, 1566.] Among those Italians who, in the sixteenth century, acquired well-merited fame as globe makers may be mentioned Ignazio Danti (1536-1586),[313] known as Pellegrino before he entered the order of the preaching friars in his nineteenth year. The name Danti appears to have been given him chiefly on account of his great learning, particularly in the field of mathematics and astronomy. In the same branches of science his father had achieved distinction, and likewise his grandfather, Vicenzo de Rinaldi, who, in the year 1571, issued a translation of the ‘Sfera’ of Sacrobosco, and who constructed, as we are told, an astrolabe and an armillary sphere.[314] It seems to have been early in the year 1563 that Danti was called to Florence by Duke Cosimo for the purpose of constructing, under his patronage, nautical and astronomical instruments and geographical maps. Of his work which is still known to us there may be first mentioned an astronomical quadrant placed on the façade of the church of Santa Maria Novella, and an equinoctial armilla placed within the same church. We have first mention in Vasari’s ‘Lives’ of the globe and map work of his which especially concerns us here. It is an interesting account of his activity in this field, an account worthy of citation. “Fra Ignazio Danti is very learned in cosmography and a man of distinguished ability in letters, in so much that the Duke Cosimo has committed to his care a work than which none more perfect in design, or more important in the results to be expected from it, has ever been executed in that kind. His excellency has caused a room of considerable extent to be prepared on the second floor of his palace, as a continuation of, and an addition to the guardaroba; around this room he has had cabinets arranged seven braccia high, and richly carved in walnut wood, intending to place within them the most valuable and beautiful works of art in his possession; and on the doors of the same he has caused fifty-seven pictures, about two braccia in height and of proportionate width, to be painted in oil on wood in the manner of miniatures. The subjects delineated are the Ptolemaic Tables, measured by Don Ignazio with the most exact perfection, and corrected according to the latest authorities; sea-charts of the utmost accuracy are added,
