It does not follow that the whole work is borrowed or fictitious. Even the great Moorish traveller Ibn Battuta, accurate and veracious in the main, seems—in one part at least of his narrative—to invent experiences; and, in such works as those of Jan van Hees and Arnold von Harff, we have examples of pilgrims to the Holy Land whose narratives begin apparently in sober truth, and gradually pass into flourishes of fiction and extravagance. So in Mandeville also we find particulars not yet traced to other writers, and which may therefore be provisionally assigned either to the writer's own experience or to knowledge acquired by colloquial intercourse in the East.
