c6.s1.t1.83

The longitude values are somewhat irregular and illustrate the inherent difficulty in the determination. The errors for Jerusalem and Cairo and Mecca seem to be traditional. The list of names on ‘Jaipur B’ (figure 13) is interesting as being copied from Ulugh Beg’s table.¹ The number of towns is the same, but the astrolabe designer left out some of the western places [*e.g.*, those in the country of Rūm and some of those of Shām (Syria) ], and added some extra towns for India. Otherwise the names, the order and the latitudes and longitudes are the same.
