Amazons
From BiblePortal Wikipedia
Amazons [1]
A fabulous race of female warriors, who had a queen of their own, and excluded all men from their community; to perpetuate the race, they cohabited with men of the neighbouring nations; slew all the male children they gave birth to, or sent them to their fathers; burnt off the right breasts of the females, that they might be able to wield the bow in war.
