Chapter DEVIL to Dhu'l Karnein of D by Brewer's Readers Handbook

Dhuldul, the famous horse of Ali, son-in-law of Mahomet.

Dhu’l Karnein [the knotty point], the forty-seventh proposition of the first book of Euclid, ascribed by some to Pythagoras.

We are also told that Dhu’l Karnein was a mysterious some-one of whom the Jews required information respecting Mahomet. (See “Cow,” Sale’s Korân, note.)

Dhu’l Karnein (“the two-horned”), a true believer according to the Mohammedan legend, who built the wall to prevent the incursions of Gog and Magog.—Al Korân, xviii.

Commentators say the wall was built in this manner: The wirkmen dug till they found water; and having laid the foundation of stone and melted brass, they built the superstructure of large pieces of iron, between which they packed wood and coal, till the whole equalled the height of the mountains [of Armenia]. Then, setting fire to the combustibles, and by the use of bellows, they made the iron red hot, and poured molten brass over to fill up the interstices.—Sale: Al Korân.
