In March, just before the lockdown, I climbed up up Dhosi hill with @ArjunSKadian. Near Haryana Rajasthan border, this hill has great historical importance as it was home to Rishi Bhrigu & his clan.1/n

The Bhrigus are both respected and somewhat feared alchemists in the Vedas. It was here that Bhrigu's eldest son Chavana invented early ayurveda medicine (including Chavanyaprash) 2/n

Dhosi is an extinct volcano & the top has a flat depression with a small temple of the Bhargava clan & the kund where Chavana is said to have been cured of disease by taking a dip. There is also a cave where he meditated. 3/n

The top is very interesting. One can see both the copper rich ridges of Khetri on side & the Ghaggar-Saraswati valley on the other. Rakhigarhi is also very close by. The Bhrigus were alchemists and were experts in bronze technology. 4/n

Interestingly we also found a bull grazing on the top. He looked like he modelled for the Harappan seals 5/n.

There is an interesting after story. When Ghori defeated Prithviraj, the latter's younger brother took refuge here and built a hideout. His fortifications are still standing. 6/n

Also interesting, note that Hemu - the great 16th century general & briefly king of Delhi - was a Bhargava (ie of Bhrigu's clan) from a village not far from Dhosi 7/n
