the teacher asked this question under the Hercules. this weblink is given by my teacher, you can answer by your own in general sense
Think of other heroes you’ve studied. What do they have in common?
I would agree that heroes all have many of the same traits. The ones mentioned above are all good ones. I like the fact that a "Code of Honor" seems to be a common trait. I also like the idea of comparing the failings of heroes.
You might also like to think about the failings of heroes. Most heroes (especially epic heroes) seem to have at least one failing that often threatens to be their downfall. For example, Enkidu suffers from the moral failing of pride that gets him into trouble. You might find it interesting to analyse a list of heroes and identify their failings and consider how these failings are used in their stories.
Another quality common to all heroes is that they have a code of behavior to which they valiantly adhere. They will die rather than betray this code of honor. In Sir Gwain and the Green Knight, for instance, Gawain values his sense of knightly virtue.
I am reminded of King Arthur, Beowulf, Perseus, and the lot. They are strong, stubborn, noble, courageous, and larger than life. They represent the people from whom they came, and they always come to the rescue of the weak (whether she's a beautiful maiden or a town in need of help in ridding themselves of a blood-thirsty villain). They almost always act from some sense of honor and/or duty--Arthur had pledged his loyalty to his knights and the people of Camelot; Beowulf came out of duty to King Hrothgar since the King had helped Beowulf's father years before, etc.
One quality all heroes of this genre share is the inevitability of fate. As mentioned above, they were a fearless bunch. It was easier to be fearless when you believed you would only die as the gods willed it. I think of Beowulf who had this very belief and fought every battle with the reckless abandon of one who is absolutely fearless in the face of death despite the great odds against him. That's certainly due, in part, to his extraordinary strength; however, it's easier to flaunt Death if you believe He can only come for you at apre-ordained, appointed time.
If we were to look at the Greek heroes, there are some definite common links. One of these common threads is the lack of fear. Heroes like Achilles, Odysseus, and Hercules share a complete abandonment of fear. These heroes are willing to stare death in the face and not hesitate to confront such a grim adversary. Part of their heroic composition is their unwillingness to retreat in the face of death. Another one of their shared links is the reality of their strength. Heroes like the aforementioned Greek standard are not weak. They are strong in both physicality and in their mentality. In the end, this level of mental austerity and brawn allows them to achieve a level of arete to which all others aspire. These are but a few of the common threads that the Greek heroes share.
Some common things that heroes have is strength. Either emotional or physical strength, it is a very common attribute. Another is courage. That is almost linked to the no fear of death trait, which is all about courage. Another is to help the misfortunate or weaker people that can not help themselves.
