Please see below a letter from Dr RN Iyengar to some of his friends, including me and our fellow blogger Kosla Vepa, followed by my reply.
Friends,
Jacobi a German indologist in 1894, argued that the Vedic people knew alpha-Draconis as their Pole Star.This claim was opposed by Whitney, Keith and others who were against arguments, however logical they might have been, that would push the Rigveda to a date more ancient than 1500 BCE. It turns out Jacobi was right, even though his arguments were weak. His opponents, claiming to know the whole of the Vedic corpus, suppressed information that would have helped Jacobi. I have pursued this topic from a totally different perspective. The complete article may be read at

Thanks. RN Iyengar
Dear Dr. Iyengar,
The evidence from BrP and TA assembled so ably by you and discussed is total.
Alpha Draconis should indeed have been the pole star known to the vedic Indians as a Dhruva star and confirmed by the Puranics as the Dhruva star asssociated with the story of Utthaanapada's son.
Jacobi would indeed be pleased. If you choose to use this beautiful analysis to give a range to date the vedic period, you will be more than justified.
Warm regards. Desikan.
