The 5 Most Terrifying Civilizations In The History of the World
They say that those who ignore history are doomed to repeat it, so pay attention for Christ's sake. It turns out that many of our ancestors achieved levels of violence that take them right out of the realm of "badass" and into the less cool area of ball-shriveling atrocity. These are the civilizations you don't want to face during, say, your next time travel adventure. And yes, the Spartans are down there. History is kind of spotty on the Celts (they never wrote anything down, and many of the witnesses died brutally) but what facts survived confirm one thing: They had gigantic Celtic balls. First of all, they had a thing for severed heads. If they felt that yours was a head of particular importance, they'd embalm it and whip it out at parties to brag about how awesome they were. The reason for all of these head-chopping-good-times was that the Celts believed that the head held the soul, and so if you cut a dead guy's head off before all of that juicy soul leaked out of it, it was yours.
