Sometime we see a cloud thats dragonish, A vapour, sometime like a bear, or lion, A towerd citadel, a pendent rock, A forked mountain, or blue promontory With trees upont, that nod unto the world, And mock our eyes with air: thou hast seen these signs; They are the black vespers pageants. Shakespeare.Antony and Cleopatra, Act IV. Scene 12. (Antony to Eros.)
Can such things be, And overcome us like a summer cloud, Without our special wonder? Shakespeare.Macbeth, Act III. Scene 4. (Macbeth, after he had seen the Ghost of Banquo.)
