“‘When your crew have taken you past these Sirens, I cannot give you coherent directions100 as to which of two courses you are to take; I will lay the two alternatives before you, and you must consider them for yourself. On the one hand there are some overhanging rocks against which the deep blue waves of Amphitrite beat with terrific fury; the blessed gods call these rocks the Wanderers. Here not even a bird may pass, no, not even the timid doves that bring ambrosia to Father Jove, but the sheer rock always carries off one of them, and Father Jove has to send another to make up their number; no ship that ever yet came to these rocks has got away again, but the waves and whirlwinds of fire are freighted with wreckage and with the bodies of dead men. The only vessel that ever sailed and got through, was the famous Argo on her way from the house of Aetes, and she too would have gone against these great rocks, only that Juno piloted her past them for the love she bore to Jason. “‘Of these two rocks the one reaches heaven and its peak is lost in a dark cloud. This never leaves it, so that the top is never clear not even in summer and early autumn. No man though he had twenty hands and twenty feet could get a foothold on it and climb it, for it runs sheer up, as smooth as though it had been polished. In the middle of it there is a large cavern, looking West and turned towards Erebus; you must take your ship this way, but the cave is so high up that not even the stoutest archer could send an arrow into it. Inside it Scylla sits and yelps with a voice that you might take to be that of a young hound, but in truth she is a dreadful monster and no one—not even a god—could face her without being terror-struck. She has twelve mis-shapen feet, and six necks of the most prodigious length; and at the end of each neck she has a frightful head with three rows of teeth in each, all set very close together, so that they would crunch any one to death in a moment, and she sits deep within her shady cell thrusting out her heads and peering all round the rock, fishing for dolphins or dogfish or any larger monster that she can catch, of the thousands with which Amphitrite teems. No ship ever yet got past her without losing some men, for she shoots out all her heads at once, and carries off a man in each mouth. “‘You will find the other rock lie lower, but they are so close together that there is not more than a bow-shot between them. [A large fig tree in full leaf101 grows upon it], and under it lies the sucking whirlpool of Charybdis. Three times in the day does she vomit forth her waters, and three times she sucks them down again; see that you be not there when she is sucking, for if you are, Neptune himself could not save you; you must hug the Scylla side and drive ship by as fast as you can, for you had better lose six men than your whole crew.’
