In the old Greek myth, Prometheus took fire from the gods and gave it to the people. For this, he was severely punished. His crime was to take knowledge that was reserved for the gods and give it to the people.
In Frankenstein, Victor Frankenstein takes the power to create life away from the gods and gives it to himself. He is clearly taking knowledge that was never meant for people to have. Because of this, he is punished as well.
To me, this is the connection between the two stories.
