Scythians - First Century AD

[Aquilae1]

First of all I want to thank all of you for your responses, most helpful

Also I was aware of the somewhat generic term for "Scythians", as used by the Romans, as well as the fact they were absorbed (if you will) by the Sarmatians.

I guess my follow up question is I have been under the impression, (from what I have read), that the Sarmatians were originally a Scythian tribe that conquered / absorbed the regional tribes around them. Understanding that over time, as they conquered other tribes, they culturally changed.

If I am understanding correctly, (which I admit I may not be), the Sarmatians originally consisted of four "sub tribes" as follows: the Lazygess, The Urgi, The Royal Scythians, and the Roxolani. So while their origin seems uncertain (Amazon women, etc) they are often associated as one of the "Scythians tribes" that outgrew the others.

So were Sarmatians originally a Scythian tribe, (or Scythian related tribe) which may be part of the reason why the Romans continued to use the term Scythian? (Again, I am not stating as fact, just from some articles I have read.)

Again thank you for responses, very much appreciated!
