15. Crucifixion
The original crucifixion, used by the Ancient Greeks and Romans, didn’t involve the actual cross. The wooden construction used was more in a T shape and often a simple plank was used. It was only later, after the most famous crucifixion in history that Christians started using a cross as their symbol. A particularly interesting detail about this method of execution was the fact that a sign of mercy was breaking victim’s legs, so they couldn’t support themselves and would die much faster. Without it, they could linger in pain for days.
