Plato’s Allegory of the Cave and Sophocles’ Oedipus the King utilize vision-related metaphors to evoke different perceptions of the human condition. Both texts extensively use metaphors related to blindness, sight, and vision to extrapolate truth and knowledge in the context of how physical sight, the human condition, and divine wisdom influence human behavior.

Physical blindness does not imply ignorance in the play “Oedipus the King,” just as physical sight does not ensure knowledge of divine truth. When Tieresias, the blind prophet, stumbles across the stage at the beginning of the play, this fact is made clear. Despite having poor physical vision, he can see into Oedipus’ past and future thanks to his internal or spiritual vision.

The King is already well known for his keen intellect despite his inability to see, particularly after correctly answering the Sphinx riddle (Minnema 440). The king eventually realizes the terrible fate that awaits him and, in his frustration, destroys his physical sight.

A low wall and a raised pathway, behind which people carry models of humans and other living things, separate the prisoners from the fire. The prisoners believe the voices of the people talking are the voices of the shadows because they can only see the shadows that the people’s movements make on the wall…
