Summary
| Description |
English: The Jantar Mantar, Jaipur is a collection of 19 astronomical instruments built in 1734. It is a UNESCO World Heritage Site.
Prakash Yantra, tracks movement of the Sun. It is based on concepts dating to as early as 300 B.C. when the Greco-Babylonian astronomer Berosus made a hemispherical sundial. This yantra includes two hemispherical bowls like sundials with graded marble slabs. The elevation, azimuth, hour angles and exact position of heavenly bodies are detected using the inverted image of the sky, and the movement of the inverted shadows on the slabs.
