From Charles Olson’s study Call Me Ishmael:
Melville wanted a god. Space was the First, before time, earth, man. Melville sought it: “Polar eternities” behind “Saturn’s gray chaos.” Christ, a Holy Ghost, Jehovah never satisfied him. When he knew peaces it was with a god of Prime. His dream was Daniel’s: the Ancient of Days, garment white as snow, hair like the pure wool. Space was the paradise Melville was exile of.
When he made his whale he made his god. Ishmael once comes to the bones a Sperm whale pitched up on land. They are massive, and his struck with horror at the “antemosaic unsourced existence of the unspeakable terrors of the whale.”
When Moby-Dick is first seen he swims a snow-hill on the sea. To Ishmael he is the white bull Jupiter swimming to Crete with ravished Europa on his horns: a prime, lovely, malignant white.
