Jai Singh's Observatory, Delhi

A preparatory sketch for plate 19 in the Daniells’ Oriental Scenery (London, 1808). The Daniells visited the Observatory at Delhi on 24 February 1789. The  monumental astronomical instrument known as the Jantar-Mantar was built around 1724. It was one of a series of observatories built by Maharaja Savai Jai Singh II of Jaipur. Thomas Daniell remarked on the '...singularity as well as the magnitude of such astronomical instruments'.
