Manuel I, Comnenus, 1143-1180. The “little book” is thought to have been one of the many forms of the legend of Prester John, a fabulous Christian ruler of India of whom much was heard in the middle ages. About 1165 a letter from the “Presbyter Johannes” addressed to the emperor Manuel Comnenus was circulated through Europe and later found its way into the North. In the extant copies of this letter many marvels are told, though the wonder mentioned in the _Speculum Regale_ does not appear. See Zarncke, _Der Priester Johannes_, 83-98. ------------------------------------------------------------------------ IX POPULAR DOUBT AS TO THE GENUINENESS OF MARVELS _Son._ Of course I cannot know how widely our talks will travel either in our days or later; and yet, with your permission, I will again ask the pleasure of hearing further speech concerning those matters that we might think strange in other lands, but which we know are surely genuine. And we need not be so very skeptical of this book which is said to have been written in India, though many marvels are told in it; for there are many things in our own country, which, though not strange to us, would seem wonderful to other people, if our words should fly so far as to come thither where such things are unheard of. But if I should express surprise at any of those tales that are told in that book, it seems to me not least wonderful that manikins are able to subdue those great winged dragons which infest the mountains and desert places there, as the book tells us, and tame them so completely that men are able to ride them just as they please like horses, fierce and venomous beasts though they are said to be and not inclined to allow men in their neighborhood, still less to be tamed and to do service.
