Centuries back, when man had no access to technology and machines, he created something that would serve us very well in the times to come. Literally! The acquisition of data using astronomy, meaning the sun, moon and stars, is a tradition that dates back to the 1600BC. And it was this tradition, which made us travel to the Konark Sun Temple in Orissa, and then, Jantar Mantar in Jaipur. Submerged in age old glory and stories of stone, these astronomical wonders were one of the earliest constructions by our ancestors that gave the world the ability to tell time. The Konark Sun Temple possesses sundials, which had, and still have the ability to tell time to the exact minute using the position of the sun. Jantar Mantar, on the other hand, is a collection of architectural astronomical instruments, which can tell the time, follow the location of stars, track ellipses and the positions of the sun, moon and planets.
