Read it through once

Akin to the adventure of Perseus and Andromeda—indeed, by some supposed to be indirectly derived from it—is that famous story of St. George and the Dragon; which dragon I maintain to have been a whale; for in many old chronicles whales and dragons are strangely jumbled together, and often stand for each other. “Thou art as a lion of the waters, and as a dragon of the sea,” saith Ezekiel; hereby, plainly meaning a whale; in truth, some versions of the Bible use that word itself. Besides, it would much subtract from the glory of the exploit had St. George but encountered a crawling reptile of the land, instead of doing battle with the great monster of the deep. Any man may kill a snake, but only a Perseus, a St. George, a Coffin, have the heart in them to march boldly up to a whale.
