Charybdis

A large fig tree in full leaf grows upon (the rock) 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, Poseidon 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.
Circe's advice to Odysseus .
Wise advice for the Scylla  lived high up in a cave where she :
 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 .... 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. 


Actually, all was calm and pleasant down at the sea - a seal swam by and looked at me, some cormorants spread their wings out on the rocks, a shrimp pottered in a rock pool and the water was a flat mercury. This pic was taken in the lake though where anything could be lurking.

The sun has only just come out (6.30pm) and himself has made risotto. Catch up later.
