Apair of rock-cut landforms can be found in India’s Jehanabad area’s Barabar and Nagarjuni hills, of which the Lomas Rishi cave is the most stunning and completely unexplainable ancient relic ― an almost 2,400-year-old cave carved with great care from solid granite.
Six crudely carved tunnels cut into big stones that litter the surrounding slopes might be interpreted as inept, an attempt to replicate what can be seen on the hill’s crest. But if you look closely, you can observe how perfectly and skillfully it was made.
It clearly displays ancient, complicated technology that has almost certainly been lost over millennia. Is this cave an evidence of a long-forgotten civilization who had such advanced knowledge ahead of its time? We would struggle to equal their sensitivity and accuracy even now.
