Rebellion
The major theme underlying the poem is that of the power of resistance to tyrannical figures. Prometheus defied the God’s by stealing their fire, which resulted in eternal punishment. However, his act of defiance resulted in the civilisation of humankind and ultimately painted both him and humans as those with “triumphant” spirits who have the power to change history.
Sacrifice
Sacrifice is another major theme of the poem. By stealing the fire, Prometheus subjected himself to eternal damnation. This is a constant source of struggle for him as he endures "the sufferings of mortality" with his own physical suffering. Ultimately, he highlights the “endurance” of individuals in doing the right thing.
Empowerment
The overall message of the poem is one that inspires individuals to take a stand. Prometheus is a symbol for hope and strength to humans, as he was able to bear the burden of his heroic actions. The poem comments on the "impenetrable Spirit" of humanity and the power to liberate themselves from tyrannical rule.
