The celestial globe has represented on its surface both the equator and the ecliptic with their respective poles indicated; circles of latitude and of longitude are omitted. The year 1600 was selected as the normal year for recording the position of the stars, and a statement is made noting the corrections becoming necessary by reason of the precession of the equinoxes. Only the Ptolemaic constellations are given, and the figures representing the same are very artistically drawn. The famous star which appeared in the year 1572 and the position of numerous comets are indicated, with the date of the appearance of each. Until the year 1862 these globes were preserved in the Altieri Library, when they were offered for sale and were purchased by Prince D. Camillo Massimo, finding a place in his palace at the Villa Peretti. If Benci, through his cosmographical studies, as well as through his other studies, brought fame to himself and to his order of Silvestrin monks, to Amantius Moroncelli, likewise a member of this order and a contemporary, no less credit should be given for his achievements as a maker of manuscript globes.[74] It has been noted that but one pair of Benci’s globes can now be located, but no less than ten constructed by Moroncelli may today be found in Italian libraries and museums, most of which possess both scientific and artistic value of a high order. A pair of his earliest globes is in the possession of the Biblioteca di S. Marco of Venice (Fig. 105). These were probably constructed as early as the year 1672 for the monastery of Cassenesi, located on the Island of S. Georgio Maggiore. The director of the S. Marco Library informs the author[75] that they have a diameter of more than 2 m., and that through want of proper care they are in a very bad state of preservation, being so darkened with age as to render their maps quite illegible. On the terrestrial globe there is a portrait, opposite which is a representation of the coat of arms of a bishop. The celestial globe is somewhat better preserved, having a title, only a part of which can be deciphered, reading “In hoc coelesti globo adnotantur omnes stellae fixae ad annum ... ac cometae,” and concluding “Extruxit D. Silvester Amantius Moroncellus Fabrianensis benedictinus sub congregationem Silvestri Abbatis. Venetiis in Augustissima bibliotheca S. Georgii Majoris....” The director of the library reads the date as 1683, others have thought it to be 1672. [Illustration: Fig. 105. Terrestrial Globe of Silvester Amantius Moroncelli, 1672.]
