As the living expression of the warmest and sincerest human feelings kissing has been credited, in the world of fairy tales and superstition, with a considerable curative and prophylactical power.
We have seen, in the old sagas and ballads, how enchantments are broken by means of a kiss; we have seen how holy men in the legends restore the sick to health by means of a kiss, etc. Kissing has, on the whole, influenced popular credulity to a large extent, and of the numerous superstitious notions concerning it I only quote some few:
If you would protect yourself against lightning you should make three crosses before you, and kiss the ground three times. (Germany.)
If you want to have luck in gambling you must kiss the cards before the game begins. (France.)
If you have the toothache you should kiss a donkey on his chops. (Germany.) This very efficacious advice is found as far back as Pliny.
If you drop a bit of bread on the floor you must kiss it when you pick it up. The same respect is also to be shown to books you have dropped. (Denmark, Germany.)
