According to Herodotus (cum gano salus: he was, after all, called both the Father of History and the Father of Lies - never met a Tall Tale he didn't like) the women of the Roxolani 'tribe' of the Scythians, the Only 'Amazon-like' fighters he mentions, were the horse archers of the tribe: the men fought in armor, with lances, but the women, supposedly, fought at a distance with bows, because they weren't allowed to marry and start a family until they had killed an enemy in combat. Taking a hard-nosed attitude towards this, they would shoot someone off his horse, then ride up and finish him off with a long knife and hack off some Very Important Part of his body to take back and prove that she had finished with this silliness and could go home now and do something really useful. According to Herodotus, other tribes really, really did not like to fight the Roxolani...
So, perhaps an Amazon on her horse with a bow in one hand and a severed head in the other and a 'You got a problem with this?" expression on her face.
