The art of tying up the wind in three knots, so that the more knots are loosed the stronger will blow the wind, has been attributed to wizards in Lappland and to witches in Shetland, Lewis, and the Isle of Man. Shetland seamen still buy winds in the shape of knotted handkerchiefs or threads from old women who claim to rule the storms. There are said to be ancient crones in Lerwick now who live by selling wind.​[1167] In the early part of the nineteenth century Sir Walter Scott visited one of these witches at Stromness in the Orkneys. He says: “We clomb, by steep and dirty lanes, an eminence rising above the town, and commanding a fine view. An old hag lives in a wretched cabin on this height, and subsists by selling winds. Each captain of a merchantman, between jest and earnest, gives the old woman sixpence, and she boils her kettle to procure a favourable gale. She was a miserable figure; upwards of ninety, she told us, and dried up like a mummy. A sort of clay-coloured cloak, folded over her head, corresponded in colour to her corpse-like complexion. Fine light-blue eyes, and nose and chin that almost met, and a ghastly expression of cunning, gave her quite the effect of Hecate.”​[1168] A Norwegian witch has boasted of sinking a ship by opening a bag in which she had shut up a wind.​[1169] Ulysses received the winds in a leathern bag from Aeolus, King of the Winds.​[1170] The {p327} Motumotu in New Guinea think that storms are sent by an Oiabu sorcerer; for each wind he has a bamboo which he opens at pleasure.​[1171] On the top of Mount Agu in Togo, a district of German West Africa, resides a fetish called Bagba, who is supposed to control the wind and the rain. His priest is said to keep the winds shut up in great pots.​[1172] [Sidenote: Frightening, driving away, and killing the spirit of the wind.]
