A new look at our ancient History

When myself and my daughter started publishing our articleson our ancient history, friends like Prof UR Prasad Of IISC and Prof VCS Rao of Arbaminch university have started asking us "have you read viswanatha satyanarayana’s Purana Vairi Granthamala" yes we did
But we we read beyond his story books We read astronomical works which most of the readers have not read
Viswanatha quotes Kota venkatachalam . His articles were written around 1950. Around the same time Thiruvenkatacharyulu has written about astronomy in Telugu Vignana Sarvasvam published by Telugu akademy. These findings were refuted By TS Kuppanna Sastry around 1959
The basis for all these articles are the articles of TS Narayana sastry in !918 ,. This has been brought to our notice by Dr Kundurthi Rajani kanth (Former IISc Professor)
