There is a third question, viz., whether besides the two channels just mentioned, there were others through which Eastern fables could have reached Europe, or Æsopian and other European fables have been transferred to the East. There are such channels, no doubt. Persian and Arab stories, of Indian origin, were through the crusaders brought back to Constantinople, Italy, and France; Buddhist fables were through Mongolian[10] conquerors (13th century) carried to Russia and the eastern parts of Europe. Greek stories may have reached Persia and India at the time of Alexander’s conquests and during the reigns of the Diadochi, and even Christian legends may have found their way to the East through missionaries, travellers, or slaves. Lastly, there comes the question, how far our common human nature is sufficient to account for coincidences in beliefs, customs, proverbs, and fables, which, at first sight, seem to require an historical explanation. I shall mention but one instance. Professor Wilson (“Essays on Sanskrit Literature,” i. p. 201) pointed out that the story of the Trojan horse occurs in a Hindu tale, only that instead of the horse we have an elephant. But he rightly remarked that the coincidence was accidental. In the one case, after a siege of nine years, the principal heroes of the Greek army are concealed in a wooden horse, dragged into Troy by a stratagem, and the story ends by their falling upon the Trojans and conquering the city of Priam. In the other story a king bent on securing a son-in-law, had an elephant constructed by able artists, and filled with armed men. The elephant was placed in a forest, and when the young prince came to hunt, the armed men sprang out, overpowered the prince and brought him to the king, whose daughter he was to marry. However striking the similarity may seem to one unaccustomed to deal with ancient legends, I doubt whether any comparative mythologist has postulated a common Aryan origin for these two stories. They feel that, as far as the mere construction of a wooden animal is concerned, all that was necessary to explain the origin of the idea in one place was present also in the other, and that while the Trojan horse forms an essential part of a mythological cycle, there is nothing truly mythological or legendary in the Indian story. The idea of a hunter disguising himself in the skin of an animal, or even of one animal assuming the disguise of another,[11] are familiar in every part of the world, and if that is so, then the step from hiding under the skin of a large animal to that of hiding in a wooden animal is not very great.
