Dating of the mahabharata by dr v vartak
Ramayan shows that the flag was being hoisted to celebrate the new year on Ashwin Paurnima (Kishkindha 16/37, Ayodhya 74/36).Ayodhya 77 mentions that the flags were defaced and damaged due to heat and showers.Vishwamitra modified this and started measuring from the nakshatra at the Autumnal Equinox. C, which is therefore the probable period when Vishwamitra existed and also that of the Ramayanic Era.Formerly, the year initiated with the Varsha-Rutu (season) and therefore was termed "Varsha".One author claims it can be dated to the 12th century BC (ibid., 166), and Hiltebeitel condemns this as baseless speculation-- it would require 800 years of oral transmission. You'd simply have to acknowledge the caveat that many of the details were still being rewritten between 400 BC and 400 AD.The dates of 7300 BC and 5561 BC are wild speculation, but the general supposition is that an underlying oral narrative does exist (ibid., 155), so the limits of how far back you want to go are defined only by the size of your imagination.Are the astronomical aspects of his method reliable? Vartak claims to have similarly dated the Mahabharata to 5561 BCE.
Just because they talk about battles between gods and demons is no reason to dismiss their accounts of kings and other contemporary developments as great story telling.
This astral configuration can be calculated to have occured around 7400 B. So it appears that the primary basis for estimating a date is the calendar by Vishwamitra.
Other estimates are arrived at relative to this conclusion.
Rama is also a hero in Indonesia (despite it being a Muslim country), in Thailand and in several other South East Asian countries.
Without the weight of historical tradition and without the stamp of truth, the Ramayana would have been swept by the tidal waves of conquests that swept India.
