In the 105th hymn of the first book of the Ṛigvedas, and in the thirty-third of the tenth book, a poet says to Indras, "The thought rends me, thy praiser, as mice tear their tails by gnawing at them."[103] But according to another interpretation, instead of "tails," we should read "threads;" in this case, the mice that rend the threads would refer to the fable of the mouse that delivers from the net now the elephant, and now the lion (of which fable I shall endeavour to prove the Vedic antiquity in the next chapter).

The twelfth story of the third book of the Pańćatantram is of great mythological interest. From the beak of a hawk (in another Hindoo legend, from two cats that are disputing for it) a mouse takes refuge in the hands of a penitent, whilst he is bathing in the river. The penitent transforms the mouse into a beautiful maiden, and wishes to marry her to the sun; the maiden declines—he is too hot. The penitent next wishes to marry her to the cloud which defeats the sun; the maiden declares it is too dark and cold. He then proposes to give her to the wind which defeats the cloud (in the white Yaǵurvedas, the mouse is sacred to the god Rudras, the wind that howls and lightens in the cloud); the maiden refuses—it is too changeful. The penitent now proposes that she should wed the mountain, against which the wind cannot prevail, but the girl says it is too hard; and finally the penitent asks if she would be willing to part with her affections to the mouse, who alone can make a hole in the mountain; the maiden is satisfied with this last proposal, and is again transformed into a female mouse, in order to be able to wed the male mouse. In this beautiful myth (which is a variation of the other one which we have already mentioned of the cat-maiden that, though transfigured, still retains its instinct as a huntress of mice), the whole revolution of the twenty-four hours of the day is described. The mouse of night appears first; the twilight tries to make it its prey; the night becomes the aurora; the sun presents itself for her husband; the sun is covered by the cloud, and the cloud is scattered by the wind; meanwhile the evening aurora, the girl, appears upon the mountain; the mouse of night again appears, and with her the maiden is confounded. The Hîtopadeças contains an interesting variety of the same myth. The mouse falls from the vulture's beak, and is received by a wise man, who changes it into a cat, then, to save it from the dog, into a dog, and finally into a tiger. When the mouse is become a tiger, it thinks of killing the wise man, who, reading its thoughts, transforms it again into a mouse. Here we find described the same circle of daily celestial phenomena. The succession of these phenomena sometimes causes transformations in the myths.

The well-known proverb of the mountain that gives birth to the mouse, refers to the myth contained in the story of the Pańćatantram. We already know that the solar hero enters in the evening with the solar horse into the mountain and becomes stone, and that all the heavens assume the colour of this mountain. From the mountain come forth the mice of night, the shadows of night, to which the cat-moon and the cat-twilight give chase; the thieving propensities of the mice display themselves in the night. In German superstition the souls of the dead assume the forms of mice, and when the head of a house dies, it is said that even the mice of the house abandon it.[104] In general, every apparition of mice is considered a funereal presage; it is on this account that the funereal St Gertrude was represented surrounded by mice. The first witch in Macbeth, when she wishes to persecute the merchant who is sailing towards Aleppo, and shipwreck him, that she may avenge herself upon his wife, who had refused to give her some chestnuts, threatens to become like a rat without a tail. In the Historia Sarmatiæ, quoted by Aldrovandi, the uncles of King Popelus II., whom, with his wife for accomplice, he murders in secret, and throws into the lake, become mice, and gnaw the king and queen to death. The same death is said to have been the doom of Miçćislaus, the son of the Duke Conrad of Poland, for having wrongfully appropriated the property of widows and orphans; and of Otto, Archbishop of Mainz, for having burned the granary during a famine. Mice are said to have presaged at Rome the first civil war, by gnawing the gold in the temple; and it was, moreover, alleged that a female mouse had given birth in a trap to five male mice, of which she had devoured two. Other prodigies, in which mice were implicated, are mentioned as having taken place at Rome, even in the times of Cato, who was accustomed to make them the butt of his indignant scorn. To a person who told him, for instance, how the mice had gnawed the boots, he answered that this was no miracle; it would have been a miracle if the boots (caligæ) had eaten the mice.

The mouse in the fable is sometimes in connection with the elephant and the lion, whom it sometimes insults and despises (as in the Tuti-Name),[105] and sometimes comes to help and deliver from their fetters. The meaning of the myth is evident: the elephant and the lion represent here the sun in the darkness; in the evening the mouse of night leaps upon the two heroic animals, which are then old or infirm; in the morning the sun is delivered out of the fetters of the night, and it is supposed that it was the mouse which gnawed the ropes and set at liberty now the elephant, as in the Pańćatantram, now the lion, as in the Æsopian fable.

The Hindoo god Gaṇeças, the god of poets, eloquence, and wisdom, is represented with an elephant's head, and his foot crushing a mouse. Thus, among the Greeks, Apollo Smintheus, so called because he had shot the mice that stole the yearly provisions from Krinos, the priest of Apollo himself, was represented with a mouse under him. As the Christian Virgin crushes the serpent of night under her foot, so does the pagan sun-god crush under his feet the mouse of night.

When the cat's away, the mice may play; the shadows of night dance when the moon is absent.

In the fifteenth story of the fifth book of Afanassieff, the witch step-mother desires her old husband to lead away his daughter to spin in the forest[106] in a deserted hut. The girl finds a little mouse there, and gives it something to eat. At night the bear comes, and wishes to play with the girl at the game of blind-man's-buff (this very popular game has evidently a mythical origin and meaning; every evening in the sky the sun amuses itself by playing blind-man's-buff; it blinds itself, and runs blind into the night, where it must find again its predestined bride or lost wife, the aurora). The little mouse approaches the maiden, and whispers in her ear, "Maiden, be not afraid; say to him, 'Let us play;' then put out the fire and hide under the stove; I will run and make the little bells ring." (Mice seem to have an especial predilection for the sound of bells. It is well-known how, in the Hellenic fable, the council of mice resolve, to deliver themselves from the cat, to put a bell round its neck; no one, however, undertakes to perform the arduous enterprise.) The bear thinks he is running after the maiden, and runs, on the contrary, after the mouse, which he cannot catch. The bear tires himself out, and congratulating the maiden, says to her, "Thou art my mistress, maiden, in playing at blind-man's-buff; to-morrow morning I will send you a herd of horses and a chariot of goods." (The morning aurora comes out of the forest, delivers herself from the clutches of the bear, from the witch of the night, and appears drawn by horses upon a chariot full of treasure. The myth is a lucid one.)

In other numerous legends we have the grateful mouse that helps the hero or heroine. In the thirteenth Calmuc story, the mouse, the monkey, and the bear, grateful for having been delivered, from the rogues that tormented them, by the son of the Brahman, come to his help by gnawing and breaking open the chest in which the young man had been enclosed by order of the king; afterwards, with the assistance of the fishes, they help him to recover a lost talisman.
