sacrifice to their new deity.[25] From the same source we also learn[26] how among savage tribes those plants that produce great terrors, excitement, or a lethargic state, are supposed to contain a supernatural being. Hence in Peru, tobacco is known as the sacred herb, and from its invigorating effect superstitious veneration is paid to the weed. Many other plants have similar respect shown to them, and are used as talismans. Poisonous plants, again, from their deadly properties, have been held in the same repute;[27] and it is a very common practice among American Indians to hang a small bag containing poisonous herbs around the neck of a child, "as a talisman against diseases or attacks from wild beasts." It is commonly supposed that a child so protected is proof against every hurtful influence, from the fact of its being under the protection of the special spirits associated with the plant it wears.

Again, closely allied to beliefs of this kind is the notion of plants as the habitation of the departing soul, founded on the old doctrine of transmigration. Hence, referring to bygone times, we are told by Empedocles that "there are two destinies for the souls of highest virtue —to pass either into trees or into the bodies of lions."[28] Amongst the numerous illustrations of this mythological conception may be noticed the story told by Ovid,[29] who relates how Baucis and Philemon were rewarded in this manner for their charity to Zeus, who came a poor wanderer to their home. It appears that they not only lived to an extreme old age, but at the last were transformed into trees. Ovid, also, tells how the gods listened to the prayer of penitent Myrrha, and eventually turned her into a tree. Although, as Mr. Keary remarks, "she has lost understanding with her former shape, she still weeps, and the drops which fall from her bark (i.e., the myrrh) preserve the story of their mistress, so that she will be forgotten in no age to come."

The sisters of Phaëthon, bewailing his death on the shores of Eridanus, were changed into poplars. We may, too, compare the story of Daphne and Syrinx, who, when they could no longer elude the pursuit of Apollo and Pan, change themselves into a laurel and a reed. In modern times, Tasso and Spenser have given us graphic pictures based on this primitive phase of belief; and it may be remembered how Dante passed through that leafless wood, in the bark of every tree of which was imprisoned a suicide. In German folk-lore[30] the soul is supposed to take the form of a flower, as a lily or white rose; and according to a popular belief, one of these flowers appears on the chairs of those about to die. In the same way, from the grave of one unjustly executed white lilies are said to spring as a token of the person's innocence; and from that of a maiden, three lilies which no one save her lover must gather. The sex, moreover, it may be noted, is kept up even in this species of metempsychosis[31]. Thus, in a Servian folk-song, there grows out of the youth's body a green fir, out of the maiden's a red rose, which entwine together. Amongst further instances quoted by Grimm, we are told how, "a child carries home a bud which the angel had given him in the wood, when the rose blooms the child is dead. The Lay of Eunzifal makes a blackthorn shoot out of the bodies of slain heathens, a white flower by the heads of fallen Christians."

It is to this notion that Shakespeare alludes in "Hamlet," where Laertes wishes that violets may spring from the grave of Ophelia (v. I):

      "Lay her in the earth,
  And from her fair and unpolluted flesh
  May violets spring."

A passage which is almost identical to one in the "Satires" of Persius (i. 39):

  "E tumulo fortunataque favilla,
  Nascentur violae;"

And an idea, too, which Tennyson seems to have borrowed:

  "And from his ashes may be made,
  The violet of his native land."

Again, in the well-known story of "Tristram and Ysonde," a further reference occurs: "From his grave there grew an eglantine which twined about the statue, a marvel for all men to see; and though three times they cut it down, it grew again, and ever wound its arms about the image of the fair Ysonde[32]." In the Scottish ballad of "Fair Margaret and Sweet William," it is related—

  "Out of her breast there sprang a rose,
  And out of his a briar;
  They grew till they grew unto the church top,
  And there they tied in a true lovers' knot."

The same idea has prevailed to a large extent among savage races. Thus, some of the North-Western Indians believed that those who died a natural death would be compelled to dwell among the branches of tall trees. The Brazilians have a mythological character called Mani—a child who died and was buried in the house of her mother. Soon a plant sprang out of the grave, which grew, flourished, and bore fruit. This plant, says Mr. Dorman,[33] was the Mandioca, named from Mani, and Oca, house. By the Mexicans marigolds are known as "death-flowers," from a legend that they sprang up on the ground stained by, "the life-blood of those who fell victims to the love of gold and cruelty of the early Spanish settlers in America."

Among the Virginian tribes, too, red clover was supposed to have sprung from and to be coloured by the blood of the red men slain in battle, with which may be compared the well-known legend connected with the lily of the valley formerly current in St. Leonard's Forest, Sussex. It is reported to have sprung from the blood of St. Leonard, who once encountered a mighty worm, or "fire-drake," in the forest, engaging with it for three successive days. Eventually the saint came off victorious, but not without being seriously wounded; and wherever his blood was shed there sprang up lilies of the valley in profusion. After the battle of Towton a certain kind of wild rose is reported to have sprung up in the field where the Yorkists and Lancastrians fell, only there to be found:

  "There still wild roses growing,
    Frail tokens of the fray;
  And the hedgerow green bears witness
    Of Towton field that day."[33]

In fact, there are numerous legends of this kind; and it may be remembered how Defoe, in his "Tour through Great Britain," speaks of a certain camp called Barrow Hill, adding, "they say this was a Danish camp, and everything hereabout is attributed to the Danes, because of the neighbouring Daventry, which they suppose to be built by them. The road hereabouts too, being overgrown with Dane-weed, they fancy it sprung from the blood of Danes slain in battle, and that if cut upon a certain day in the year, it bleeds."[34]

Similarly, the red poppies which followed the ploughing of the field of Waterloo after the Duke of Wellington's victory were said to have sprung from the blood of the troops who fell during the engagement;[35] and the fruit of the mulberry, which was originally white, tradition tells us became empurpled through human blood, a notion which in Germany explains the colour of the heather. Once more, the mandrake, according to a superstition current in France and Germany, sprang up where the presence of a criminal had polluted the ground, and hence the old belief that it was generally found near a gallows. In Iceland it is commonly said that when innocent persons are put to death the sorb or mountain ash will spring up over their graves. Similar traditions cluster round numerous other plants, which, apart from being a revival of a very early primitive belief, form one of the prettiest chapters of our legendary tales. Although found under a variety of forms, and in some cases sadly corrupted from the dress they originally wore, yet in their main features they have not lost their individuality, but
