| This is one of the many strange looking astronomical devices in the Jantar Mantar Observatory; one of the sundials here was capable of resolving down to the half second. Built by Maharaja Jai Singh in 1725, it is one of five that he built; I later saw the only one still in working order in Jaipur. |
