What a fascinating find for today’s MotM. While it was built for use as a scientific instrument, to me it’s a beautiful piece of art. This sculpture provides more evidence for me in support of the idea that science can be used and presented in a creative, artistic way…and all the more reason to bring science and art together more often.

The Jai Prakash Yantra structure is part of  the Jantar Mantar monument of Jaipur, Rajasthan. It

“is a collection of nineteen architectural astronomical instruments, built by the Rajput king Sawai Jai Singh, and completed in 1738 CE. It features the world’s largest stone sundial.” – wikipedia

It is one of 19 structures in the whole collection and consists of

“two hemispherical bowl-based sundials with marked marble slabs that map inverted image of [the] sky and allows the observer to move inside the instrument, measures altitudes, azimuths, hour angles and declinations.”

Here’s a photo of the second bowl shot by Beth Moon and posted on her flickr site.

And finally, here’s a photo of the site for a bit of perspective on the size of these two bowls (where the two larger groupings of people are standing).
