Who said just as an eagle swooped down from the crags where it was born and bred just as it snatched that goose fattened up for the kill inside the house?

The quote you provided is from the ancient Greek philosopher and playwright Aeschylus, specifically from his work "Prometheus Bound." In this play, the imagery of the eagle symbolizes Zeus's punishment of Prometheus, who stole fire for humanity. The eagle represents the power of Zeus, while the goose symbolizes Prometheus’s vulnerability and the consequences of his defiance.
