One thing you will realize by the end of this list is that people, at least in the past, were very fond of cannibalism, sacrifice, and torture. As a case in point, not long ago as several archaeologists were searching through the sewers beneath a Roman/Byzantine bathhouse in Israel when they came across something terrifying…baby bones, and lots of them. For whatever reason someone in the bathhouse above apparently felt compelled to dispose of hundreds of babies in the sewer below.

Although it has been known for years that the Aztecs hosted numerous bloody sacrificial festivals, in 2004 a grisly discovery was made outside of modern day Mexico City. Numerous decapitated and mutilated bodies of both humans and animals shed some light on just how horrific the rituals could get.

Unlike modern burials, Egyptians didn’t take into account the fact that if you don’t strap the chin to the skull, it will fall open in a permanent scream. Although most mummies exhibit this sort of profile, it can get significantly more terrifying. Every once in a while archaeologists discover mummies that seem to have truly been screaming at their death due to some sort of ritual torture. The one above is name Unknown Man E and was found by Gaston Masparo in 1886.
