The "media" of the ancient world was the medium of oral tradition. Stories, passed from city to city by travelers, evolved into myths, and the great tales became legends. Poetic license was used liberally to emphasize certain aspects of the stories' themes, or the heroes' strengths and foibles. Of course, bards would no doubt exaggerate the physical feats of their heroes to make audiences happy.
Taken as archetypes, heroes are a combination of opposites. Well-formed mythic heroes possess a signature strength or skill, which they use to accomplish their heroic acts. Heroes will likewise possess foibles that mark them as human, or at least as imperfect. It is the tension between these two details that make heroes compelling. As a result, every hero and their adventures are inseparable because the experience is what lays bare the hero's weaknesses, and showcases their strengths.
