As I stood here below, methought his eyes
Were two full moons; he had a thousand noses,
Horns whelked and waved like the enragèd sea.
It was some fiend. Therefore, thou happy father,
Think that the clearest gods, who make them honours
Of men’s impossibilities, have preserved thee.
– William Shakespeare
King Lear, Act 4, Scene 6. Edgar tries to trick Gloucester into believing that the "beggar" who led him to the "cliffs" at Dover so that he could jump and commit suicide was a devil and that the gods saved his life. In reality Edgar brings Gloucester across level ground and not the cliffs, where he only falls a few feet and passes out. Thus Edgar helps his father regain his faith and also rid him of his suicidal thoughts. Edgar has disguised his voice and his blind father doesn’t recognize him.
