Indian cosmology never ceases to amaze, whether it's a matter of Hindu eclipse demons or the highly precise astronomical architecture we see represented in this 1808 aquatint by T & W Daniell. It's called the Samrat Yantra (giant sundial) at Jantar Mantar, an outdoor astronomical observatory in Delhi constructed in the early 18th century at the behest of Maharajah Jai Singh II (1686-1743).

Sigh questioned the accuracy of European, Islamic and Hindu astronomical tables inaccurate, so he built several observatories to accurately measure the position of the sun, stars, moon and planets via naked eye sight and massive, precise construction.
