| omschrijving | Islamic globe. Astronomical details on the sphere include stars and constellations. The zodiacal figures are engraved with dotted lines, and a total of 74 stars labelled in Arabic. The ecliptic longitudes of eight stars have been determined. By comparing these values for the longitudes with those in the Ptolemaic catalogue for AD 137, and using the Arabic rate of precession, the epoch of the stars has been determined as 1622, with an uncertainty of 24 years. For full details about the cartography and construction of this globe please refer to the related publication.
