History has and always will be shrouded in mystery. Despite documentation, we will never truly know everything that has happened in the past. This is what makes history so incredibly interesting — and obscure.
While some of our biggest questions about the past may remain unknown, we have managed to answer some. From discovering what really happened to the lost colony of Roanoke to debunking the mysteries of the Bermuda Triangle, these are the biggest questions from the past that have been answered.
For hundreds of years, we never had a way of deciphering hieroglyphs. That is, until Jean-François Champollion came along.
The Roman “Gate to Hell”
Over 2,000 years ago, people from around the region would come to a Greco-Roman temple in Hierapolis to a cave that was believed to be an entrance into the underworld. Priests would bring sacrificial animals into a cave known as “Plutonium” where the animals would die upon entering. From bulls to birds, the Greek geographer Strabo wrote that “any animal that passes inside meets instant death.”
However, in 2013, it was discovered that the entrance to the cave emits deadly amounts of carbon dioxide — more than enough to kill a large animal. They also believe because the animals were lower to the ground they died quickly.
