There is a legend from Greek mythology that the god Hercules was once walking along a narrow road when a strange-looking creature appeared threateningly in front of him.
Hercules struck this creature with his club and passed on, but soon afterwards was surprised to be confronted by this same creature, only now three times as large.
Hercules struck it again and again and each time it grew in size until finally it completely blocked the road.
Then the goddess Pallas Athena appeared to Hercules and told him to stop.
"The monster is called Strife," she said. "Let it alone, and it will soon become as small as it was at first."
