The Folk-lore of Plants

John Ray, in his treatise on "The Wisdom of God in Creation," was among the first to express his disbelief of this idea, and writes:--"As for the signatures of plants, or the notes impressed upon them as notices of their virtues, some lay great stress upon them, accounting them strong arguments to prove that some understanding principle is the highest original of the work of Nature, as indeed they were could it be certainly made to appear that there were such marks designedly set upon them, because all that I find mentioned by authors seem to be rather fancied by men than designed by Nature to signify, or point out, any such virtues, or qualities, as they would make us believe." His views, however, are somewhat contradictory, inasmuch as he goes on to say that, "the noxious and malignant plants do, many of them, discover something of their nature by the sad and melancholick visage of their leaves, flowers, or fruit. And that I may not leave that head wholly untouched, one observation I shall add relating to the virtues of plants, in which I think there is something of truth--that is, that there are of the wise dispensation of Providence such species of plants produced in every country as are made proper and convenient for the meat and medicine of the men and animals that are bred and inhabit therein." Indeed, however much many of the botanists of bygone centuries might try to discredit this popular delusion, they do not seem to have been wholly free from its influence themselves. Some estimate, also, of the prominence which the doctrine of signatures obtained may be gathered from the frequent allusions to it in the literature of the period. Thus, to take one illustration, the euphrasia or eye-bright (Euphrasia officinalis), which was, and is, supposed to be good for the eye, owing to a black pupil-like spot in its corolla, is noticed by Milton, who, it may be remembered, represents the archangel as clearing the vision of our first parents by its means:--
