By this time the sun was about to set, and all of a sudden the sky became as dark as if it had been covered with a thick cloud. I was much astonished at this sudden darkness, but much more when I found it was occasioned by a bird of a monstrous size, that came flying toward me. I remembered that I had often heard mariners speak of a miraculous bird called the roc,[52] and conceived that the great dome which I so much admired must be its egg. In short, the bird alighted, and sat over the egg. As I perceived her coming, I crept close to the egg, so that I had before me one of the legs of the bird, which was as big as the trunk of a tree. I tied myself strongly to it with my turban, in hopes that the roc next morning would carry me with her out of this desert island. After having passed the night in this condition, the bird flew away as soon as it was daylight, and carried me so high that I could not discern the earth; she afterward descended with so much rapidity that I lost my senses. But when I found myself on the ground, I speedily untied the knot, and had scarcely done so, when the roc, having taken up a serpent of a monstrous length in her bill, flew away. The spot where it left me was encompassed on all sides by mountains, that seemed to reach above the clouds, and so steep that there was no possibility of getting out of the valley. This was a new perplexity; so that when I compared this place with the desert island from which the roc had brought me, I found that I had gained nothing by the change. [Footnote 52: Mr. More, in his account of these voyages, says that Marco Polo, in his _Travels_, and Father Martini, in his _History of China_, speak of this bird, called _ruch_, and say it will take up an elephant and a rhinoceros. It is as fabulous as the dodo, the salamander, or the phoenix.] As I walked through this valley, I perceived it was strewn with diamonds, some of which were of surprising bigness. I took pleasure in looking upon them; but shortly I saw at a distance such objects as greatly diminished my satisfaction, and which I could not view without terror, namely, a great number of serpents, so monstrous that the least of them was capable of swallowing an elephant. They retired in the daytime to their dens, where they hid themselves from the roc, their enemy, and came out only in the night.
