Vizhignam - as this place is now known - is a Shore town as most of us are aware of. Hence Educational Academy teaching martial Arts - Military disciplines including ship building - ship wars etc., theories are put forward. Geographical point also made it a watch point to monitor any help from the West to Ealam. Pandyas & Cheras almost shared their borders near this Western Sea port.
Can we compare Poompuhar & Chidambaram in the same way on the East for Cholas? Are you aware that there exists a KEEZHACHALAI near Thiruvengadu even today?
Awaiting Pandyas Copper plate details.,
Re Srirangam there is another theory : Ranganatha was worshipped by Itshwaghu .. ancestor of Sri Rama. Kodai Nachiyar wedded Sri Ranganatha and thus considered respectable even by Sita Devi .. When one takes pradakshinam, he will walk slowly when moving away from Ranganatha's feet (East to West ) and walk quickly when moving toward the feet (towards East?!) Unending & untiring ..
