When Hercules sets off to find the nine-headed hydra accompanied by his nephew Iolaus, he probably didn't think of the risk Iolaus was taking on his behalf. Hercules being the strongest man alive, was used to impossible tasks and pleasing the gods with his strength. On the other hand, his nephew Iolaus could have been very strong, but he certainly wasn't any match for Hercules.
You don't hear much about Iolaus, because he is a minor character isn't worth that much in stories or myths. It took a great deal of courage from Iolaus to slay the hydra. Hercules seemed very unafraid of the hydra because of his super human strength. All in all Hercules was a tad conceited and thought very much of himself and his strengths. When you're his accomplice you can't help but feel inferior to his strength. Iolaus must have had to overcome that fear of the dreaded hydra to be able to battle it as fiercely as Hercules had.
In my tapestry I am going to connect the virtue of courage to overcoming and acknowledging fear when faced with mortal danger or a dangerous quest. I will explore the scale of courage, from those who believe that fear is just a matter of overcoming, exploring, accepting, resisting, or mastering.
