Read it through once

But go to the old Galleries, and look now at a great Christian painter’s portrait of this fish; for he succeeds no better than the antediluvian Hindoo. It is Guido’s picture of Perseus rescuing Andromeda from the sea-monster or whale. Where did Guido get the model of such a strange creature as that? Nor does Hogarth, in painting the same scene in his own “Perseus Descending,” make out one whit better. The huge corpulence of that Hogarthian monster undulates on the surface, scarcely drawing one inch of water. It has a sort of howdah on its back, and its distended tusked mouth into which the billows are rolling, might be taken for the Traitors’ Gate leading from the Thames by water into the Tower. Then, there are the Prodromus whales of old Scotch Sibbald, and Jonah’s whale, as depicted in the prints of old Bibles and the cuts of old primers. What shall be said of these? As for the book-binder’s whale winding like a vine-stalk round the stock of a descending anchor—as stamped and gilded on the backs and title-pages of many books both old and new—that is a very picturesque but purely fabulous creature, imitated, I take it, from the like figures on antique vases. Though universally denominated a dolphin, I nevertheless call this book-binder’s fish an attempt at a whale; because it was so intended when the device was first introduced. It was introduced by an old Italian publisher somewhere about the 15th century, during the Revival of Learning; and in those days, and even down to a comparatively late period, dolphins were popularly supposed to be a species of the Leviathan.
