The Astronomical Observatories of Jai Singh c9.s1.33

c9.s1.33

34. Of other masonry instruments there are the Miśra Yantra (‘mixed instrument’) at Delhi and the Rāśi Valaya (zodiac dials) at Jaipur. There are some indications that these two instruments, or rather sets of instruments, were not devised by Jai Singh, and, therefore, they will be described in detail when the observatories at Delhi and Jaipur are dealt with. The most notable feature of the Miśra Yantra is the set of arcs for meridians at Greenwich and Zurich on the west, and two corresponding places on the east. The Rāśi Valaya is a set of twelve dials connected with the rising signs, and which show the sun's latitude and longitude.
