THE NORSEMEN 5 Britain and a great continent beyond the sea where Saturn slept. Other almost prophetic utterances of the kind have been culled from classical authors, but they have mostly the air of specula- tion. It cannot be said that the Greeks or Romans devoted much energy to the remoter reaches of the ocean.
