In Dr. Jackson’s Works (1673) we read that he once questioned one of his parishioners as to what he saw or heard when he watched the falling of the Fern-seed, whereupon the man informed him that this good seed is in the keeping of Oberon (or Elberich), King of the Fairies, who would never harm anyone watching it. He then said to the worthy doctor, “Sir, you are a scholar, and I am none. Tell me, what said the angel to our Lady; or what conference had our Lady with her cousin Elizabeth, concerning the birth of St. John the Baptist?” Finding Doctor Jackson unable to answer him, he told him that “the angel did foretell John Baptist should be born at that very instant in which the Fern-seed—at other times invisible—did fall: intimating further that this saint of God had some extraordinary vertue from the time or circumstance of his birth.”
To catch the wonder-working seed, twelve pewter plates must be taken to the spot where the Fern grows: the seed, it is affirmed, will pass through eleven of the plates, and rest upon the twelfth. This is one account: another says that Midsummer night is the most propitious time to procure the mystic Fern-seed, but that the seeker must go bare-footed, and in his shirt, and be in a religious state of mind.
In ancient days it was thought the demons watched to convey away the Fern-seed as it fell ere anyone could possess themselves of it. A writer on Brittany states that he remembers to have heard recounted by one who had gathered Fern-seed, that whilst he was prosecuting his search the spirits grazed his ears, whistling past them like bullets, knocking off his hat, and hitting him with it all over his body. At last, when he thought that he had gathered enough of the mystic seed, he opened the case he had been putting it into, and lo! it was empty. The Devil had evidently had the best of it.
M. Marmier, in his Légendes des Plantes, writes:—“It is on Midsummer night that you should go and seek the Fern-seed: he who is fortunate enough to find it will indeed be happy. He will have the strength of twenty men, he will discover precious metals in the bowels of the earth, he will comprehend the present and the future. Up to the present time, however, no one has been able to secure this precious seed. It ripens but for a minute, and the Devil guards it with ferocious vigilance.”
De Gubernatis, in his Mythologie des Plantes, publishes a communication sent him by the Princess Marie Galitzin Prazorovskaïa, on the subject of the flowering of the Fern, the details of which she obtained from a Russian peasant. “On Midsummer night, before twelve o’clock, with a white napkin, a cross, a Testament, a glass of water, and a watch, one seeks in the forest the spot where the Fern grows; one traces with the cross a large circle; one spreads the napkin, placing on the cross the Testament and the glass of water. Then one attentively looks at one’s watch: at the precise midnight hour the Fern will bloom: one watches attentively; for he who shall see the Fern-seed drop shall at the same time see many other marvels; for example, three suns, and a full moon, which reveals every object, even the most hidden. One hears laughter; one is conscious of being called; if one remains quiet one will hear all that is happening in the world, and all that is going to happen.”
In a work by Markevic, the author says:—“The Fern flowers on Midsummer night at twelve o’clock, and drives away all unclean spirits. First of all it put forth buds, which afterwards expand, then open, and finally change into flowers of a dark red hue. At midnight, the flower opens to its fullest extent, and illuminates everything around. But at that precise moment a demon plucks it from its stalk. Whoever wishes to procure this flower must be in the forest before midnight, locate himself near the Fern, and trace a circle around it. When the Devil approaches and calls, feigning the voice of a parent, sweetheart, &c., no attention must be paid, nor must the head be turned, for if it is, it will remain so. Whoever becomes the happy possessor of the flower has nothing to fear: by its means he can recover lost treasure, become invisible, rule on earth and under water, and defy the Devil. To discover hidden treasure, it is only necessary to throw the flower in the air: if it turns like a star above the Sun, so that it falls perpendicularly in the same spot, it is a sure indication that treasure is concealed there.”
A very ancient method prescribed for obtaining the mystic Fern-seed is given by Dr. Kuhn. At the Summer solstice, if you shoot at the Sun when it has attained its mid-day height, three drops of blood will fall: they must be gathered up and preserved, for that is the Fern-seed.
The Franche-Comté peasantry talk of a mysterious plant that misleads travellers. According to a German authority, this plant is no other than the Fern on Midsummer night. As we have seen, on that night the Fern is reputed to flower, and to let fall its seed: he who secures this seed, becomes invisible; but if the unsuspecting traveller passes by the Fern without noticing it, he will be assuredly misled, even although well acquainted with the road. This is the reason why, in Thuringia, they call the Fern Irrkraut, the misleading plant.
In Poland, there is a popular notion that the plucking of Fern produces a violent thunderstorm.
In Germany, they call the Fern Walpurgiskraut, the superstition being that, on the Walpurgisnacht, the witches procure this plant in order to render themselves invisible. In Lombardy, there exists a popular superstition akin to this. The witches, they say, are particularly fond of the Fern; they gathered it to rub in their hands during a hailstorm, turning it from the side where the hail falls the thickest.
