The globe with a diameter of 127 cm rests on a robust wooden base with the clockwork for rotation inside. Wooden ribs of the globe´s frame are covered with thin sheet metal to make them robust and light. Constellations are painted on parchment or paper, glued to the properly shaped surfaces of the brass sheet and fixed on the ribs from the outside. On the horizon belt are the Latin names of the winds and a calendar. The globe was made in 1725 by Caspar Pflieger (1665-1730), a mechanician and the first custodian of the Klementinum Mathematical Museum (Musaeum mathematicum). The globe bears the coat of arms of Bishop Johann Rudolph Count Sporck, canon of the Prague chapter at St. Vitus, and the year 1725, indicating thus the probable sponsor and the year of the origin. Depicted are sixty-seven constellations, the Pleiades and the Milky Way. Source: Šolc, Martin – Hvězdný glóbus Caspara Pfliegera; http://wwwold.nkp.cz/bp/bp2001_4/13.htm
