The Astronomical Observatories of Jai Singh c10.113

c10.113

The graduated parts of the Jai Prakāś require refacing either with marble or other suitable stone. The original was in lime plaster, but it did not last very long; and in 1910 the facing was again done in lime plaster, but the graduations are already becoming obliterated (see figures 32 and 33). The central iron rod (galvanised piping) should be removed and the cross wires replaced.
