Did you ever wonder how people could see their way around at night before street lights?
In ancient times, if travelers didn’t make it to the safety of a city before dark, they would have to spend the night in a very dark and hazardous situation. They were at the mercy of such things as hungry lions, poisonous vipers and such. But, a huge bonfire was kindled every night outside city gates to show travelers the way. In the pitch-black of the desert, travelers headed toward the light of the signal fire.
