In Greek mythology, what was the name of mortal that discovered fire?
There is no specific name for the mortal who discovered fire as it was a God who gave them fire. The God Prometheus gave humanity fire. This is because, Zeus had given all the other creatures on earth tools for them to survive apart from humans who were too scared to come out, so Prometheus who liked the humans went down and gave them fire, so they could hunt,keep warm and protect themselves from wild animals.
According to Greek mythology Promethius sneaked into the heavens and stole the fire form the Gods themselves and ran with a branch of it down mount olympus and gave it to man. Zeus was said to be so nagered that for his punishment he was tied to a rock and an eagle was sent to peck out his liver. Every night his liver grows back and every morning the eagle comes back to peck it out again. It was said that his punishement would last for as long as man uses fire.
