A Jantar Mantar (Hindustani pronunciation: [d͡ʒən̪t̪ər mən̪t̪ər]) is an assembly of stone-built astronomical instruments, designed to be used with the naked eye. There were five Jantar Mantars in India,all of them built at the command of the RajahJai Singh II, who had a keen interest in mathematics, architecture and astronomy; The largest example is the equinoctialsundial belonging to Jaipur's assembly of instruments, consisting of a gigantic triangular gnomon with the hypotenuse parallel to the Earth's axis. On either side of the gnomon is a quadrant of a circle, parallel to the plane of the equator. The instrument can be used with an accuracy of about 20 seconds by a "skilled observer" to measure the time of day, and the declination of the Sun and the other heavenly bodies. It is the world's largest stone sundial, known as the Samrat Yantra.[1][2] The Jaipur Jantar Mantar is a UNESCO World Heritage Site.[3]
In the early 18th century, MaharajaJai Singh II of Jaipur constructed five Jantar Mantar in total, in New Delhi, Jaipur, Ujjain, Mathura and Varanasi; they were completed between 1724 and 1735.The Mathura one was 95 percent destroyed by the Mughals .
The Jantar have like[clarification needed] Samrat Yantra, Jai Prakash, Ram Yantra and Niyati Chakra; each of which are used to for various astronomical calculations. The primary purpose of the observatory was to compile astronomical tables and to predict the times and movements of the sun, moon and planets.
The name "Jantar Mantar" is at least 200 years old, finding a mention in an account from 1803.[4] However, the archives of Jaipur State, such as accounts from 1735 and 1737–1738, do not use this as Jantra, which in the spoken language is corrupted to Jantar.[4] The word Jantra is derived from yantra, instrument, while the suffix Mantar is derived from mantrana meaning consult or calculate.[4]
