Surface: The Key to Understanding Moby-Dick
There are many key themes and words in Herman Melville's Moby-Dick. One of the more interesting words found repeatedly is the word surface. There are several ways to interpret this word; it is the veil under which the unknown resides, it is the dividing line between the limits of human knowledge and that which is unknowable, it is the barrier that protects the soul from falling below, and it is a finite form .

According to Ishmael, the phrenological study of the sperm whale's head is more difficult than solving the riddle of the sphinx and is like finding an answer to pi. Subsequently, in chapter sixty-eight (The Blanket) Ishmael uses the whale as a metonym calling it a hieroglyphic pyramid adding, "Like those mystic rocks, too, the mystic marked whale
