‘Sever’d Sicilia from the western shore.’ 9

Next, as you will be able to sail close to Charybdis, of which the poets have sung, you will see that greediest of whirlpools, quite smooth if no south wind be blowing, but whenever there is a gale from that quarter, sucking down ships into a huge and deep abyss. You will see the fountain of Arethusa, so famed in song, with its waters bright and pellucid to the very bottom, and pouring forth an icy stream which it either finds on the spot or else plunges it under ground, conveys it thither as a separate river beneath so many seas, free from any mixture of less pure water, and there brings it again to the surface. You will see a harbour which is more sheltered than all the others in the world, whether they be natural or improved by human art for the protection of shipping; so safe, that even the most violent storms are powerless to disturb it.
