(M52) More famous, however, than these are the marvellous properties which popular superstition in many parts of Europe has attributed to the fern at this season. At midnight on Midsummer Eve the plant is supposed to bloom and soon afterwards to seed; and whoever catches the bloom or the seed is thereby endowed with supernatural knowledge and miraculous powers; above all, he knows where treasures lie hidden in the ground, and he can render himself invisible at will by putting the seed in his shoe. But great precautions must be observed in procuring the wondrous bloom or seed, which else quickly vanishes like dew on sand or mist in the air. The seeker must neither touch it with his hand nor let it touch the ground; he spreads a white cloth under the plant, and the blossom or the seed falls into it. Beliefs of this sort concerning fern-seed have prevailed, with trifling variations of detail, in England, France, Germany, Austria, Italy, and Russia.(225) In Bohemia the magic bloom is said to be golden, and to glow or sparkle like fire.(226) In Russia, they say that at dead of night on Midsummer Eve the plant puts forth buds like glowing coals, which on the stroke of twelve burst open with a clap like thunder and light up everything near and far.(227) In the Azores they say that the fern only blooms at midnight on St. John’s Eve, and that no one ever sees the flower because the fairies instantly carry it off. But if any one, watching till it opens, throws a cloth over it, and then, when the magic hour has passed, burns the blossoms carefully, the ashes will serve as a mirror in which you can read the fate of absent friends; if your friends are well and happy, the ashes will resume the shape of a lovely flower; but if they are unhappy or dead, the ashes will remain cold and lifeless.(228) In Thuringia people think that he who has on his person or in his house the male fern (_Aspidium filix mas_) cannot be bewitched. They call it St. John’s root (_Johanniswurzel_), and say that it blooms thrice in the year, on Christmas Eve, Easter Eve, and the day of St. John the Baptist; it should be dug up when the sun enters the sign of the lion. Armed with this powerful implement you can detect a sorcerer at any gathering, it may be a wedding feast or what not. All you have to do is to put the root under the tablecloth unseen by the rest of the company, and, if there should be a sorcerer among them, he will turn as pale as death and get up and go away. Fear and horror come over him when the fern-root is under the tablecloth. And when oxen, horses, or other domestic cattle are bewitched by wicked people, you need only take the root at full moon, soak it in water, and sprinkle the cattle with the water, or rub them down with a cloth that has been steeped in it, and witchcraft will have no more power over the animals.(229)
