I've been reading a book that I got from my public library named The Reach of Rome by Derek Williams. It talks about the beginning of the permanent roman frontier. Most of the subjects he touches on I can agree with and I can back up with historical data. But one statement bothers me. He states that the Getai were a Sarmation not Thracian people. This doesn't sound right to me since in all the sources I've read about them it specifically states that they were of Thracian stock. It even says it on wikipedia http://en.wikipedia.org/wiki/Getae. Am I wrong because this looks like blatant error or oversight . Please EB team help me in this perplexing problem.
