1) Both texts emphasize the strength of mortals over that of the gods.
Explanation:
Here's what the poet says: [From the story of Prometheus,]
"A mighty lesson we inherit: Thou art a symbol and a sign
To Mortals of their fate and force; Like thee, Man is in part divine,"
The sufferings inflicted by Gods or fate can seem to be unbearable. But although the flesh may be weak, the spirit can still be strong. And that's what Byron confirms in conclusion:
"To which his <u>Spirit may oppose</u> Itself—and equal to all woes,
And <u>a firm will,</u> and <u>a deep sense</u>, Which even in torture can descry
<u>Its own concenter'd recompense</u>, Triumphant where it dares defy,
And making Death a Victory."
