.The contact between the Romans and the people of Sanatana Dharma is quite ancient.

Vedic texts refer to there areas as Yavana, though it is normally taken s denoting the Greeks.

Yavanas are referred to in The Vedas,Mahabharata and Tami Literature speaks  in detail about Yavanas.

The Great Tmail epic Silappdikarm, which is set in the background of Madurai and Poompuhar, called as Kaverippompattinam mentions that Yavanas hd a flourishing Trade with all the Tamil Kings, Chera, Chola and Pandyas.

The trade reached its peak during the period of Augustus and the Roman currency depreciated alarmingly.

During Augustus’s period ratio of Gold to 1:9.3 aureus, aureus being 25 Silver Dinari.

Because of the heavy import from India, the ratio became 1:96 during the period of Nero and this economic decline was one of the reasons for Rome’s .disintegration as an Empire.

 

 

‘The recorded history of the city goes back to the 3rd century BCE, being mentioned by Megasthenes, the Greek ambassador to India, and Kautilya, a minister of the Mauryan emperor Chandragupta Maurya.
