amongst their authors had it."

_D'Herbelot_ says:

"_Dhoul_ (or _Dhu_) _carnun_, _with the two horns_, is the
surname of _Alexander_, that is, of an ancient and fabulous
Alexander of the first dynasty of the Persians. 795. Article
Sedd, Tagioug and Magioug. 993. Article Khedher. 395. b. 335. b.
Fael.

"But 317. Escander, he says, Alexander the Great has the same
title secondarily. The truth probably is the reverse, that the
fabulous personage was taken from the real conqueror.

"_Hofmann_, in Seleucus, says that the area of Seleucus is
called Terik Dhylkarnain, i.e. Epocha Alexandri Cornigen. Tarik
means probably the date of an event."

There can be no doubt that the word in Chaucer is this Arabic word; nor,
I think, that Speght's story is really taught by the Arabs, our teachers
in mathematics. Whether the application is from Alexander, (they would
know nothing of his date with regard to Pythagoras), or merely from
two-horned, is doubtful. The latter might possibly mean the ox.

Mr. Halliwell gives a quotation from Stanyhurst, in which it means "dull
persons"--an obvious misuse of it for Englishmen, and which Skene
fortifies by an A.-S. derivation, but which is clearly not Cressida's
meaning, or she would have said, "I _am_ Dulcarnon," not "I _am at_
Dulcarnon;" and so Mrs. Roper.
