Titan is a metonymy for Prometheus himself. The speaker addresses him directly, calling attention to his immortal, greater-than-human status. Prometheus is portrayed suffering for giving fire to humanity, symbolizing knowledge and power. The speaker questions Prometheus’ choice “What was thy pity’s recompense?” (5) essentially, what did he gain in return, which is answered as silent suffering on the rock above the lake. By directly addressing Prometheus as “Titan,” Byron adds more force to the message that there can be victory in suffering.
