“Others say that the Nile flows from snowy mountains, and they are the mountains called Kaf. That it passes through the Green Sea, and over gold and silver and emerald and ruby mines, flowing on _ad infinitum_ until it reaches the lake of the Zingh (Zanzibar), and they say were it not to enter into the salt sea and be mixed up with the waters thereof, it could not be drunk for great sweetness.” “There is a difference of opinion as to the derivation of the word ‘Gumr.’ Some say it ought to be pronounced ‘Kamar,’ which means the moon, but the traveller, Ti Tarshi, says that it was called by that name because ‘the eye is dazzled by the great brightness.’ This mountain, the Gumr, extends eastward and westward into uninhabited territory on both sides. Indeed, this whole chain is uninhabited on the southern slope. This chain has peaks rising up into the air, and other peaks lower. Some have said that certain people have reached these mountains, and ascended them and looked over to the other side, where they saw a sea with troubled waters, dark as night, this sea being traversed by a white stream, bright as day, which enters the mountains from the north, and passes by the grave of the Great Hermes, and Hermes is the prophet Idrisi (Enoch).” “It is said that Idrisi there built a dome. Some say that people have ascended the mountain, and one of them began to laugh and clap his hands,[16] and threw himself down on the further side of the mountain. The others were afraid of being seized with the same fit, and so came back. It is said that those who saw it, saw bright snows like white silver glistening with light.[17] Whoever looked at them became attracted, and stuck to them until they died, and this science is called ‘Human Magnetism.’” “It is said that a certain king sent an expedition to discover the Nile sources, and they reached copper mountains, and when the sun rose, the rays reflected were so strong that they were burnt. Others say that these people arrived at bright mountains like crystal, and when the rays of the sun were reflected they burnt them. Others say that Mount Gumr is a mountain on an island which is called by this same name. Opposite to it is the land of Serendib,[18] four months’ journey in length and twenty days’ journey in breadth, and that from this mountain comes the bird called gimre.”
