Most legends are based on fact. Here's another example. http://www.pbs.org/wnet/secrets/previous_seasons/case_amazon/about.html#
There's been plenty of evidence for a long time that the Skythians (pre Hun steppe nomads) had female warriors. No news here. Also according to the Greeks the Amzons were from Africa.
I have a friend whos mom was Mrs John Deere. Great guy who does good things with his wealth. Rufus is a big man, 6-4, 280+, and his wife is a pretty 6-0 big breasted blonde. She just spent 3 months in the Amazon basin living with the 4 foot Indians learning their herbology.. She is the stuff legends are made of in the back country.
I believe that the Greeks had the Amazons in what today is Turkey. Anyway, this is based on genetic evidence linking blond, blue-eyed girls in Mongolia to the Caucusus.
