In France, Piedmont, and Switzerland, the country-people tell of a certain Herb of Oblivion which produces loss of memory in anyone putting his foot upon it. This herb also causes wayfarers to lose their way, through the unfortunates forgetting the aspects of the country, even although they were quite familiar to them before treading on the Herb of Forgetfulness. Of a somewhat similar nature must have been the fruit of the Lotos-tree, which caused the heroes of the Odyssey to forget their native country.
King Solomon, whose books on Magic King Hezekiah destroyed lest their contents should do harm, ascribed great magical powers to a root which he called Baharas (or Baara). Josephus, in his History of the Jewish Wars, states that this wonderful root is to be found in the region of Judæa. It is like a flame in colour, and in the evening appears like a glittering light; but upon anyone approaching it with the idea of pulling it up, it appears to fly or dart away, and will avoid its pursuer until it be sprinkled either with menstrual blood or lotium femininum.
“The Mandrake’s charnel leaves at night”
possess the same characteristic of shining through the gloom, and, on that account, the Arabians call it the Devil’s Candle.
The ancients knew a certain herb called Nyctilopa, which had the property of shining from afar at night: this same herb was also known as Nyctegredum or Chenomychon, and geese were so averse to it, that upon first spying it they would take to instant flight. Perhaps this is the same plant as the Johanniswurzel or Springwort (Euphorbia lathyris), which the peasants of Oberpfalz believe can only be found among the Fern on St. John’s Night, and which is stated to be of a yellow colour, and to shine at night as brightly as a candle. Like the Will-o’-the-Wisp, the Johanniswurzel eludes the grasp of man by darting and frisking about.
Several plants are credited with possessing the power of preservation from thunder and lightning. Pliny mentions the Vibro, which he calls Herba Britannica, as a plant which, if picked before the first thunderblast of a storm was heard, was deemed a safeguard against lightning. In the Netherlands, the St. John’s Wort, gathered before sunrise, is credited with protective powers against lightning. In Westphalia, the Donnerkraut (the English Orpine, or Live-long) is kept in houses as a preservative from thunder. In England, the Bay is considered a protection from lightning and thunder; the Beech was long thought to be a safeguard against the effects of lightning; and Houseleek or Stonecrop, if grown upon a roof, is still regarded as protecting the house from being struck by lightning. The Gnaphalium, an Everlasting-flower, is gathered on the Continent, on Ascension Day, and suspended over doorways, to fulfil the same function. In Wales, the Stonecrop is cultivated on the roof to keep off disease.
The Selago, or Golden Herb of the Druids, imparted to the priestess who pressed it with her foot, the knowledge of the language of animals and birds. If she touched it with iron, the sky grew dark, and a misfortune befell the world.
The old magicians were supposed to have been acquainted with certain plants and herbs from which gold could be extracted or produced. One of these was the Sorb-tree, which was particularly esteemed for its invaluable powers; another was a herb on Mount Libanus, which was said to communicate a golden hue to the teeth of the goats and other animals that grazed upon it. Niebuhr thinks this may be the herb which the Eastern alchymists employed as a means of making gold. Father Dundini noticed that the animals living on Mount Ida ate a certain herb that imparted a golden hue to the teeth, and which he considered proceeded from the mines underground. It was an old belief in Germany, by the shores of the Danube, and in Hungary, that the tendrils and leaves of the Vines were plated with gold at certain periods, and that when this was the case, it was a sure sign that gold lay hidden somewhere near.
Plutarch speaks of a magical herb called Zaclon, which, when bruised and thrown into wine, would at once change it into water.
Some few plants, like the well-known Sesame of the ‘Arabian Nights,’ are credited with the power of opening doors and obtaining an entry into subterranean caverns and mountain sides. In Germany, there is a very favourite legend of a certain blue Luck-flower which gains for its fortunate finder access to the hidden recesses of a mountain, where untold riches lie heaped before his astonished eyes. Hastily filling his pockets with gold, silver, and gems, he heeds not the presence of a dwarf or Fairy, who, as he unknowingly drops the Luck-flower whilst leaving the treasure-house, cries “Forget not the best of all.” Thinking only of the wealth he has pocketed, he unheedingly passes through the portal of the treasure cave, only just in time to save himself from being crushed by the descending door, which closes with an ominous clang, and shuts in for ever the Luck-flower, which can alone open the cave again.
