Though Manu is reported to have sprung from Vivaswan,Surya,Sun, and recorded as first Human, Offspring of Saptha Rishis are shown as progenitors of Human race.For example Daksha.Saptha Rishis change for each Manvantara.
Chozha genealogy tallies with Matsya Purana,Vishnu Purana.
The Order of Kings is not followed in Tamil.
Marici is the father of Kasyapa.Tamil says it is the other way around,which is incorrect.
However, Names of other Kings tally.
Surya,Sun is mentioned in Tamil as well as the First of the Dynasty, Kasyapa and Marici being Rishis.
Tamil conveys the purport of Sisumara Chakra aspect of Surya, by calling Sun as ‘ one who drives a chariot with one Wheel.
Tamil also calls Sun as one who rules lands within all Boundaries, implying that Sun covers the whole land.
Marici is known for his truthfulness. Tamil also records this by calling him as ‘Mythakka Mayaru Kaatchiyon.
Manu is correctly called as the son of Surya,Sun.
Tamil adds one information that Manu dispensed Justice to a Cow.
There is also a view that Poompuhar,Kaverippommpattinam,the harbour of Chozhas was submerged because of failure to celebrate Indira festival.
However,the information is that Sibi or his descendants established the Madra Kingdom. This is located in the northwest of India.This confirms my earlier view that Sibi , Chola King ruled from the Northern part of India ,
Shibi, Vara, Krmi, Dakshas were the sons of king Ushinara.
So That makes Sibi as the Great Grand son of Yayati.Yayati and Devayani , Daughter of Sukracharya were the ancestors of of Sibi .Yayai and Devayani were the parent’s of Sibi’s Grandfather,Anu.
