Lanka

[3][4] Some scholars have interpreted the content of these texts to determine that Lanka was located at the point where the Prime-Meridian of India passes the Equator.

The most original of all the existing versions of Valmiki's Ramayana also suggest the location of Ravana's Lanka to be in the western Indian Ocean.

It indicates that Lanka was in the midst of a series of large island-nations, submerged mountains, and sunken plateaus in the western part of the Indian Ocean.

[9][10][11][12] This speculation is supported by the presence of Minicoy Island in the vicinity between India and Maldives, the ancient name being Minikaa, or Mainaka (the mountain met by Hanuman on his way to Lanka), which in the ancient language of the place means "cannibal", probably a reference to Sursa, as cannibals from the Nicobars were frequently found here, along with snakes.

Sahadeva, the son of Pandu, conquered the town of Sanjayanti and the country of the Pashandas and the Karanatakas utilizing his messengers alone and made all of them pay tributes to him.

And, He has arrived at the seashore, then dispatched with great assurance messengers unto the illustrious Vibhishana, the grandson of Pulastya and the ruler of Lanka (2:30).

The Vangas and Angas and Paundras and Odras and Cholas and Dravidas and Cheras and Pandyas and Mushika and Andhakas, and the chiefs of many islands and countries on the seaboard as also of frontier states, including the rulers of the Sinhalas, the barbarous mlecchas, the natives of Lanka, and all the kings of the West by hundreds, and all the chiefs of the seacoast, and the kings of the Pahlavas and the Daradas and the various tribes of the Kiratas and Yavanas and Sakras and the Harahunas and Chinas and Tukharas and the Sindhavas and the Jagudas and the Ramathas and the Mundas and the inhabitants of the kingdom of women and the Tanganas and the Kekayas and the Malavas and the inhabitants of Kasmira... (3:51).
