Jantar Mantar

Under
patronage from the emperor, he set on himself the task of correcting the existing
astronomical tables and updating the almanac with more reliable instruments.
Delhi's Jantar Mantar is the first of the five observatories that he built with
large masonary instruments.
At first sight, the Jantar Mantar appears like a gallery of modern art.
It is, however, an observatory. Sawai Jia Singh II of Jaipur (1699-1743), a
keen astronomer and a noble in the Mughal court, was dissatisfied by the errors
of brass and metal astronomical instruments.
The observatory has the Samrat Yantra, a simple equal hour sun dial, the Ram
yantra for reading altitudinal angles; Jai Prakash for ascertaining the position
of the sun and other celestial bodies, and the Misra Yantra which is a combination
of four scientific gadgets.
