The video discusses three fascinating things about ancient India that are not commonly known. Firstly, chess was invented in India, where it was initially known as ashtapada and eventually evolved into chaturanga during the Gupta Empire's Reign.

Travelers, artists, and even royalty carried different variations of the game along the Silk Road, eventually introducing it to Persia and Japan, where it underwent further adaptations. Secondly, the mausoleum of Emperor Humayun in Delhi is a historically significant architectural masterpiece constructed in 1570.

It holds the distinction of being the first Garden tomb in the Indian subcontinent and is part of a cluster of 16th-century Mughal Garden tombs. Thirdly, the dancing girl of Mohenjodaro is a 4500-year-old bronze statuette from the ancient Indus Valley Civilization, discovered in 1926. Crafted through the lost wax casting technique, the dancing girl showcases the mastery of bronze artistry during her time.
