India’s mythology, amazing temple carvings and sacred texts are full of stories of incredible technologies. From flying chariots to moving idols in mythological texts, all these mythological machines indicate that the thinkers and makers of India must have had much more knowledge of technology than we think. Some people consider it a myth, while others would compare it to real inventions lost to history.

In ancient texts, there is mention of optical instruments, which served as special lenses or mirrors used to study the stars and also to reflect light in temples.
