There are universal stories that resurface with each generation, slightly modified to meet the times. These stories will emerge, almost as if there is a social need for them, at certain moments in history.
We count these moments - moments when we dare to aim higher, to break barriers, to reach for the stars or to make the unknown known - we count these moments as our highest achievements.
The epic tales we tale are meant to inspire greatness, to remind us of what can be done or what can be lost when man goes astray.
But the way those stories get told give us a bit of focus on the temper of our times.
If you look closely enough, you'll see certain personality traits emerging in our heroes or being retconned into our legends.
Just an observation.
