In many regions of Christendom it is related that these demons, relatives of the Swan-maidens, considered in another chapter, have been converted into friendly or even pious creatures, and baptized into saintly names. Sometimes there are legends which reveal this transition. Thus it is related that in the year 1440, the dikes of Holland being broken down by a violent tempest, the sea overflowed the meadows; and some maidens of the town of Edam, in West Friesland, going in a boat to milk their cows, espied a mermaid embarrassed in the mud, the waters being very shallow. They took it into their boat and brought it to Edam, and dressed it in women’s apparel, and taught it to spin. It ate as they did, but could not be brought to speak. It was carried to Haarlem, where it lived for some years, though showing an inclination to water. Parival, who tells the story, relates that they had conveyed to it some notions of the existence of a deity, and it made its reverences devoutly whenever it passed a crucifix.
Another creature of the same species was in the year 1531 caught in the Baltic, and sent as a present to Sigismund, King of Poland. It was seen by all the persons about the court, but only lived three days.
Fig. 6.—Hercules and the Hydra (Louvre).
The Hydra—the torrent which, cut off in one direction, makes many headways in others—has its survivals in the many diabolical names assigned to boiling springs and to torrents that become dangerously swollen. In California the boiling springs called ‘Devil’s Tea-kettle’ and ‘Devil’s Mush-pot’ repeat the ‘Devil’s Punch-bowls’ of Europe, and the innumerable Devil’s Dikes and Ditches. St. Gerard’s Hill, near Pesth, on which the saint suffered martyrdom, is believed to be crowded with devils whenever an inundation threatens the city; they indulge in fiendish laughter, and play with the telescopes of the observatory, so that they who look through them afterwards see only devils’ and witches’ dances!35 At Buda, across the river from Pesth, is the famous ‘Devil’s Ditch,’ which the inhabitants use as a sewer while it is dry, making it a Gehenna to poison them with stenches, but which often becomes a devastating torrent when thaw comes on the Blocksberg. In 1874 the inhabitants vaulted it over to keep away the normal stench, but the Hydra-head so lopped off grew again, and in July 1875 swallowed up a hundred people.36
The once perilous Strudel and Wirbel of the Danube are haunted by diabolical legends. From Dr. William Beattie’s admirable work on ‘The Danube’ I quote the following passages:—‘After descending the Greinerschwall, or rapids of Grein above mentioned, the river rolls on for a considerable space, in a deep and almost tranquil volume, which, by contrast with the approaching turmoil, gives increased effect to its wild, stormy, and romantic features. At first a hollow, subdued roar, like that of distant thunder, strikes the ear and rouses the traveller’s attention. This increases every second, and the stir and activity which now prevail among the hands on board show that additional force, vigilance, and caution are to be employed in the use of the helm and oars. The water is now changed in its colour—chafed into foam, and agitated like a seething cauldron. In front, and in the centre of the channel, rises an abrupt, isolated, and colossal rock, fringed with wood, and crested with a mouldering tower, on the summit of which is planted a lofty cross, to which in the moment of danger the ancient boatmen were wont to address their prayers for deliverance. The first sight of this used to create no little excitement and apprehension on board; the master ordered strict silence to be observed, the steersman grasped the helm with a firmer hand, the passengers moved aside, so as to leave free space for the boatmen, while the women and children were hurried into the cabin, there to await, with feelings of no little anxiety, the result of the enterprise. Every boatman, with his head uncovered, muttered a prayer to his patron saint; and away dashed the barge through the tumbling breakers, that seemed as if hurrying it on to inevitable destruction. All these preparations, joined by the wildness of the adjacent scenery, the terrific aspect of the rocks, and the tempestuous state of the water, were sufficient to produce a powerful sensation on the minds even of those who had been all their lives familiar with dangers; while the shadowy phantoms with which superstition had peopled it threw a deeper gloom over the whole scene.’
Concerning the whirlpool called Wirbel, and the surrounding ruins, the same author writes: ‘Each of these mouldering fortresses was the subject of some miraculous tradition, which circulated at every hearth. The sombre and mysterious aspect of the place, its wild scenery, and the frequent accidents which occurred in the passage, invested it with awe and terror; but above all, the superstitions of the time, a belief in the marvellous, and the credulity of the boatmen, made the navigation of the Strudel and the Wirbel a theme of the wildest romance. At night, sounds that were heard far above the roar of the Danube issued from every ruin. Magical lights flashed through their loopholes and casements, festivals were held in the long-deserted halls, maskers glided from room to room, the waltzers maddened to the strains of an infernal orchestra, armed sentinels paraded the battlements, while at intervals the clash of arms, the neighing of steeds, and the shrieks of unearthly combatants smote fitfully on the boatmen’s ear. But the tower on which these scenes were most fearfully enacted was that on the Longstone, commonly called the ‘Devil’s Tower,’ as it well deserved to be—for here, in close communion with his master, resided the ‘Black Monk,’ whose office it was to exhibit false lights and landmarks along the gulf, so as to decoy the vessels into the whirlpool, or dash them against the rocks. He was considerably annoyed in his quarters, however, on the arrival of the great Soliman in these regions; for to repel the turbaned host, or at least to check their triumphant progress to the Upper Danube, the inhabitants were summoned to join the national standard, and each to defend his own hearth. Fortifications were suddenly thrown up, even churches and other religious edifices were placed in a state of military defence; women and children, the aged and the sick, as already mentioned in our notice of Schaumburg, were lodged in fortresses, and thus secured from the violence of the approaching Moslem. Among the other points at which the greatest efforts were made to check the enemy, the passage of the Strudel and Wirbel was rendered as impregnable as the time and circumstances of the case would allow. To supply materials for the work, patriotism for a time got the better of superstition, and the said Devil’s Tower was demolished and converted into a strong breastwork. Thus forcibly dislodged, the Black Monk is said to have pronounced a malediction on the intruders, and to have chosen a new haunt among the recesses of the Harz mountains.’
When the glaciers send down their torrents and flood the Rhone, it is the immemorial belief that the Devil may be sometimes seen swimming in it, with a sword in one hand and a golden globe in the other. Since it is contrary to all orthodox folklore that the Devil should be so friendly with water, the name must be regarded as a modern substitute for the earlier Rhone demon. We probably get closer to the original form of the superstition in the Swiss Oberland, which interprets the noises of the Furka Glacier, which feeds the Rhone, as the groans of wicked souls condemned for ever to labour there in directing the river’s course; their mistress being a demoness who sometimes appears just before the floods, floating on a raft, and ordering the river to rise.
There is a tidal demonolatry also. The author of ‘Rambles in Northumberland’ gives a tradition concerning the river Wansbeck: ‘This river discharges itself into the sea at a place called Cambois, about nine miles to the eastward, and the tide flows to within five miles of Morpeth. Tradition reports that Michael Scott, whose fame as a wizard is not confined to Scotland, would have brought the tide to the town had not the courage of the person failed upon whom the execution of this project depended. This agent of Michael, after his principal had performed certain spells, was to run from the neighbourhood of Cambois to Morpeth without looking behind, and the tide would follow him. After having advanced a certain distance he became
