Geologists have dated Tirupati Hills range and the information tallies with what Hindu Puranas say about the age of the Hills. It is about 2100 Million years old.

Based on this and references to this mountain by Tamil literature one can infer Tamils , to have described this mountain, should have lived when it was in existence and also when Himalayas was formed around 70 Million years ago.Tamil hints at the emergence of Himalayas by the pressure of tectonic plates , by saing that Sage Agastya was sent to South to balance the earth as Himalayas was pressed down and Southern plateau tilted up.’வடதிசை இமயமும், தென்திசை ஆய்குடியும் உலகைச் சமனிலை கொள்ளச் செய்யும். – புறம் 132′ This poem 132 from Puranaanuru states that Himalayas of the North and the Clan of Ay, a Tamil Clan shall balance the earth.There are innumerable poems that state Sage Agastya came to South while Siva Parvathi marriage took palce to regain earth’s balance and Tamilnadu has Temples where Siva was reported to have given Darshan of His marriage with Parvathi to Agastya as Agastya could not be present at Himalayas.

Then we have the seven Root Races of the world.Among these are Lemuria.This is dated around 230 Million years old where it existed .I had written on this and also on MU civilization.

Now landmass which was later known as Aryavartha, how was it called? Aryavartha people and Puran call South of Vindhyas as Dravida Desa ,Southern Country.

What did Dravida Desa people call the Northern landmass?

Navalantheevu, நாவலன் தீவு.Navalpazham is the name for Jamboo fruit in Tamil.How do puranas, Shruthi and Smriti describe Landmass? Jamboothdweepe Bharathavarshe Bharathak kande ‘( Sankalpa we do in Pooja and on religious occasions).Tamil therefore refers to North as Navalan theevu.It was surrounded by oceans.

And what did lie between Thiruvengadam, the Northern boundary of Tamils and Himalayas.Vindhyas and Satpura mountain ranges, called as Krauncha Parvatha.Tamil literature refers to it as the landmass that lay as (lies now Vindhya and Satpura) Krauncha parvatha and Subrahmanya, Murugan broke it into two with his Vel ,Spear. ‘மாய அவுணர் மருங்கு அறத் தபுத்தவேல், நாவலந்தண்பொழில் வடமொழி ஆயிடைக் குருகொடு பெயர்பெற்ற மால்வரை உடைத்து, மலையாற்றுப்படுத்த மூவிரு கயந்தலை – பரிபாடல் 5-9 Paripadal 5- 9.(Murugan broke with his Spear the Mountain that lay between the land of Ay Clan and Land where people spoke Sanskrit) குருகு எறி வேலோய் – பரிபாடல் 19-36 (The one with Spear thou had throrn it to break open the Range.)

So Tamil land was different from Aryavartha.Aryavartha was called Navalan Theevu,Jaboodweepa.These two were separated by Vindhya and Satpura mountains.South of it lay the Northern boundary of Tamils. Tamil Literature asserts this.And Northern territory was surrounded by oceans.
