The Lancisiana Biblioteca of Rome possesses an artistically constructed armillary sphere, apparently the work of Giovanni Maria Barrocci, who, in the second half of the sixteenth century, achieved distinction as a maker of watches and of mathematical instruments. Fiorini gives reason for thinking this to be of about the year 1570, as well as reason for attributing the work to Barrocci,[325] finding it in an epitaph of a member of the family in which there is allusion to the construction of a celestial globe for Pope Pius V. Two globes, one celestial attributed to Hieronymo de Boncompagni, and one terrestrial attributed to Emanuele Filiberto and probably constructed about the year 1570, are briefly referred to by Fiorini as belonging to the Osservatorio del Collegio Romano.[326] Further reference to these globes has not been obtainable, there being no mention of the same in a communication received by the author from this observatory. The Biblioteca Nationale Vittorio Emanuele of Rome possesses two remarkably fine manuscript globes, a terrestrial and a celestial, the latter bearing the inscription “Anno Jobel[327] 1575 ad que supputatae sunt stellae.” “In the Jubilee year for which the positions of the stars have been computed.” While not giving with certainty the exact date of their construction, it seems that it could not have been later than that given in the legend. The globes bear the coat of arms of the Jesuits, which may only suggest that the maker was a member of that order. Each of these globes, or globe balls, is constructed of a wooden framework, covered with a preparation of plaster, over which has been added a coat of thick varnish. On the surface thus prepared the map has been drawn and painted in colors. Each has a diameter of about 70 cm., is mounted on a pyramidal base, 77 cm. in height, from which rises a rod 45 cm. in length, supporting two semicircles which serve as a direct base support for the iron horizon circle. The celestial globe has represented on its surface the equator, the tropics, the polar circles, the colures, the ecliptic, and the zodiac, and the figures representing the several constellations. These figures are very artistically painted, having their several names written in gold in the Latin language; some figures and names unfortunately are wanting by reason of injury to the surface of the globe. On the terrestrial globe the equator, the tropics, and the polar circles are represented, while but two meridians are indicated, the prime meridian passing through the Canary Islands while the other has been drawn ninety degrees from this, that is, cuts it at right angles at the poles.
