"Exaggeration, hyperbolism, excessiveness are generally considered fundamental attributes of the grotesque style."
"Of all the features of the human face, the nose and mouth play the most important part in the grotesque image of the body; the head, ears, and nose also acquire a grotesque character when they adopt the animal form or that of inanimate objects... [The grotesque] is looking for that which protrudes from the body, all that seeks to go out beyond the body's confines. Special attention is given to the shoots and branches, to all that prolongs the body and links it to other bodies or to the world outside... But the most important of all human features for the grotesque is the mouth. It dominates all else. The grotesque face is actually reduced to the gaping mouth; the other features are only a frame encasing this wide-open bodily abyss."
