Thou art a boil,
A plague-sore, an embossed carbuncle,
In my corrupted blood.
– William Shakespeare
King Lear, Act 2, Scene 4. Lear rages about the unfair treatment he has received from Goneril and says that they’ll never meet or see each other again. While admitting that she is his flesh and blood and daughter, he cannot come to terms with this. He using graphic disease metaphors in this passage to describe her as a boil, plague sore and tumor that corrupts his blood. Relations between dad and mean daughter have reached a new and unforgiving low.
