Name
The name "Jantar Mantar" is at least 200 years old, being mentioned in an account from 1803.[5] 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.[5] The word Jantra is derived from yantra, instrument, while the suffix Mantar is derived from mantrana meaning consult or calculate.[5]
