40 Strange Photos That Make You Do a Double Take

Here’s the deal with pentagrams: they’re not just for metal bands and Satanists anymore. In fact, did you know that the pentagram has been used as a symbol for various meanings and cultures throughout history? The Greek mathematician Pythagoras used them to represent the five elements, so they’re not so weird.

Even the ancient Egyptians used it as a symbol of the five senses! According to a survey, only 1% of people with pentagram tattoos are actually Satanists. So, before judging someone for having a pentagram tattoo, remember that it could symbolize their love for math or sense of smell.
