of Interest Jantar Mantar

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.
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.
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.
