The Astronomical Observatories of Jai Singh c10.10

c10.10

On the top of the gnomon is a circular pillar, which was probably used originally for rough azimuth observations, but which is now surmounted by a small sundial of the European type. This was probably constructed in 1910: the pillar, but not the dial, appears in the Daniells' drawings (figures 43 and 44).²
