An excellent example of this first issue may be found in the Museum of The Hispanic Society of America (Fig. 102), this being one of the most valuable in its large collection. It has a diameter of 50 cm., and is mounted on a wooden base having four feet, which, though evidently very old, is clearly not the original base. It is furnished with a narrow wooden horizon circle which is not graduated, and the calendar and other representations, which one usually finds pasted on this circle in early globes, are entirely wanting. The meridian circle of iron, likewise, is not graduated, and like the wooden base is not a part of the original mounting. The sphere itself is remarkably well preserved, there being scarcely a noticeable injury to its surface save the slight discoloration of age. The engraved gore map covering the papier-mâché ball, which is of very light construction, is composed of twelve sections, or rather of twenty-four, since each of the sections is cut at the equator, and the poles are covered with small circular discs. [Illustration: Fig. 102. Terrestrial Globe of Mattheus Greuter, 1632.] In the south Atlantic and near the great southern continent, in a neat cartouch surmounted by the coat of arms of the Boncompagni family of Bologna, is the following dedication: “Illustrissimo et Excellentissimo Principi D. Iacobo Boncompagno Sorae Arcisque Duci Marchioni Vignolae Aquini Comiti Dno suo colendissimo. Mattheus Greuter Humill. obseqii ergo. D. D.” “To the Most Illustrious and Excellent Prince Lord Jacob Boncompagni, Duke of Sora and Arce, Marquis of Vignola and Count of Aquino, his Most Worshipful Lord Mattheus Greuter with humble obedience dedicates (this globe).” Iacopo Boncompagni, to whom Greuter dedicated his work, belonged to a famous family of Bologna.[58] He was born in Sora in the year 1613 and died in the year 1636. It was his great-grandfather, Hugo, who, in the year 1572, at the age of seventy, became Pope Gregory XIII, and who immortalized himself through his reform of the calendar. Iacopo, the grandfather of that member of the family to whom Greuter dedicated his globe, was in position, at the time of the elevation of his father to the Papacy, to have bestowed upon him great honors and riches. He was nominated Castellan of St. Angelo, and shortly thereafter, receiving the title General of the Holy Church, was sent to Ancona with a commission to defend the maritime regions of the papal states. He was soon thereafter admitted to the nobility of Rome, of the Kingdom of Naples, and of Venice. Through the riches of the Papacy he was able to purchase from Alfonso II of Este the Marquisate of Vignola for seventy-five thousand Roman scudi, the Duchy of Sora and of Arce from the Duke of Urbino for one hundred and ten thousand ducats, and the lands of Arpino and Roccasecca, together with the County of Aquino from Alfonso of Avalon, Marquis of Guasto, for one hundred and forty thousand ducats.
