The quote you provided is a slightly inaccurate rendition of the myth of Prometheus from Greek mythology. While the essence of the story is captured in the quote, there are some discrepancies with the original myth.
In Greek mythology, Prometheus was indeed a Titan who sided with the humans and defied the gods by stealing fire from Mount Olympus and giving it to humanity. Fire was considered a symbol of knowledge, civilization, and progress. As a result of his actions, Prometheus was punished by Zeus, the king of the gods, in a rather gruesome manner.
According to the most well-known version of the myth, Prometheus was bound to a rock or pillar, and an eagle (not birds) was sent by Zeus to peck out his liver daily. The twist here is that because Prometheus was immortal, his liver would regenerate overnight, and the eagle would return to repeat the punishment each day.
The punishment of Prometheus was meant to be eternal torment, as Zeus wanted to make an example of him and deter other Titans and humans from challenging the authority of the gods.
The myth of Prometheus has been interpreted in various ways throughout history, often seen as a symbol of the struggle for knowledge and progress against oppressive forces, and as a representation of the human quest for enlightenment and defiance against divine authority.
