The Jains comprise about 0.4 percent of India's population of 1.2 billion and are a generally religious, prosperous and literate community.
Historian Sugam Anand said: "The findings should have led to serious research, but that was not done. You need time and resources. Definitely before Akbar built his capital in Fatehpur Sikri, there is proof of habitation, of temples and commercial centres. The open space on the ridge was used by Akbar to build his capital. But we still need a lot of research."
The statues and artefacts discovered buried in a pond have been kept in a guest house in Fatehpur Sikri by the ASI.
