The Astronomical Observatories of Jai Singh c4.s2.9

c4.s2.9

Observations were made at most of the important places through which they passed. The observatories at Delhi and Jaipur are mentioned but not those at Benares and Mathurā, at both of which places they made astronomical observations, and this means that the observatories at Benares and Mathurā were probably built after their visit, which took place in the early part of 1734.
