Annotation is the process of commenting on or explaining an existing text.
Annotation can reveal not only the content of the text but also the beliefs of the one annotating. The man who never in his mind and thoughts traveled to heaven is no artist. Artists who are above a plain understanding are mocked and destroyed by this president of fools. In annotating Reynolds's text, Blake is turning what perhaps Reynold expected to be a monologue into a dialogue. Read the McCormick and Scholes sections with a pen.
