Scythians were a civilization that flourished as per present evolving study of Ancient Human civilizations, in Central Asia, sometimes described as Inner Asia.
The Scythian people were referred to in Mahabharatha, one of the two great Epics of India as Milechas, that is those who do not follow Vedic system of Living.
They were called as Sakas and the region they lived was called Saka Dweepa, Saka Island.
The island might refer to the present Black Sea and the Sakas could have lived north of Black Sea in the present Russia.
There is ample evidence of these people having evolved from India tribes.
And look at the reference in Mahabharatha here.
‘Sakas are described in Sanskrit sources as a Mlechcha tribe grouped along with the Yavanas, Tusharas and Barbaras. There were a group of Sakas called Apa Sakas meaning water dwelling Sakas, probably living around some lake in central Asian steppes. Sakas took part in Kurukshetra War….
Note that Siva who was only indirectly mentioned in the Vedas through Sri Rudram, there is no Siva Suktha or Hymns directly addressed to Shiva, is mentioned as having been worshiped in Saka Dweepa.
Not only this.
IT was a place where Siddhas lived.
Siddhas are unique to Tamil Culture.
They were realized Souls.
Shiva is regarded as the First Siddha, Adi Siddha.
Agastya, Bhogar and Panini ere his chief disciples.
Agastya along with Shiva is believed to have founded Tamil Language.
Tamil is still spoken in its rudimentary form in the North Western province of present Pakistan.
Tamil Chola King, Sibi ancestor of Lord Rama ruled from the northwest Region of India, where his second capital was located.
Alexander when he invaded India subdued the Sagodas a sub tribe of Sakas.
His wife Roxane was a Saka or Sagoda probably.
IT looks as though the Scythians were connected to Tamils or were Tamils.
Will be writing on Tamils and Scythians:the Vasishta connection to Scythians:Scythian Tamil land anamoly.
