(1) In the northern ocean there is a fish, called the Leviathan, many thousand li in size. This leviathan changes into a bird, called the Rukh, whose back is many thousand li in breadth. With a mighty effort it rises, and its wings obscure the sky like clouds. At the equinox, this bird prepares to start for the southern ocean, the Celestial Lake. And in the Record of Marvels we read that when the rukh flies southwards, the water is smitten for a space of three thousand li around, while the bird itself mounts upon a typhoon to a height of ninety thousand li, for a flight of six months' duration. Just so are the motes in a sunbeam blown aloft by God. For whether the blue of the sky is its real colour, or only the result of distance without end, the effect to the bird looking down would be just the same as to the motes. If there is not sufficient depth, water will not float large ships. Upset a cupful into a small hole, and a mustard-seed will be your boat. Try to float the cup, and it will stick, from the disproportion between water and vessel. So with air. If there is not a sufficient depth, it cannot support large birds. And for this bird a depth of ninety thousand li is necessary; and then, with nothing save the clear sky above, and no obstacle in the way, it starts upon its journey to the south.

(5) There are places where that fish is written of as 'the Ariz of the water;' as it says that the greatest of the creatures of Aûharmazd is that fish, and the greatest of those proceeding from the evil spirit is that lizard; with the jaws of their bodies, moreover, they snap in two whatever of the creatures of both spirits has entered between them, except that one fish which is the Vâs of Pankâsadvarân.

(7) And the disk of the sun was a great dragon whose tail was in his mouth and who reached to seven powers of the Left and whom four powers in the form of white horses drew. And the base of the moon had the type of a ship which a male and a female dragon steered and two white bulls drew. The figure of a babe was on the stern of the moon who guided the dragons who robbed the light from the rulers. And on its prow was a cat's face. And the whole world and the mountains and the seas fled together to the west to the left.
