Dravidians refer to a mythical continent - Kumari Kandam in their ancient texts written 18 to 20 centuries back
Pl read my posts - Sanskrit is a dravidian origin, South Brahmins are Dravidians. Jain texts written 1000s of years back clearly say Ramayana & Mahabarata are stories of Dravidian Cheiftains, this is stated by the Archealogy dept of India.
In Ramayana, Ravana is described as a "White Man" - Blonde hair (Golden hair like Sun), Blue eyes (eyes like deep blue sea), White Skin (Skin color like the white clouds). Dravidians knew the White Man very well & they talk about them living in their land, and the mixed race. Rama is Dark skinned, Lakshmana is White. etc..
