The legend of the building of the wall, in the fabulous Eastern lives of Alexander, is to be found in the 18th chapter of the Koran; and it is related with variations and amplification by Sir John Mandeville. The metrical as well as prose romances on the subject of Alexander also contain it; and those who wish for more information will find it in the third volume of Weber's _Metrical Romances_, p. 331. I cannot say that I am quite convinced of the truth of the ingenious supposition of your correspondent, that "Sending to Dulcarnein is merely an ellipsis of the person for his place, _i.e._ for the rampart of Dulcarnein." It appears to me more probable, that as, according to St. Jerome and other writers of the Middle Ages, the _Dilemma_ was also called Syllogismum _Cornutum_, its Arabic name was _Dhu 'lkarnein_; and we know how much in science and literature the darker ages were indebted to the Arabian writers. Wyttenbach, in his _Logic_, says "_Dilemma_ etiam _Cornutus_ est; quod _utrimque_ veluti _Cornibus_ pugnat." At any rate it is clear that the enclosure had another name: "En Ynde si naist uns grans mons Qui est une grans regions C'on apiele _Mont Capien_. Illuec a unes gens sans bien, Qu' Alixandres dedens enclost, Et sont la gent _Got_ et _Magot_." _Extrait de l'Image du Monde, par Le Roux de Lincy, Livre des Légendes_, p. 208. It does not appear to me that _to be at Dalcarnon_ is equivalent to being _sent to Coventry_, or to Jericho, as your correspondent A. N. supposes; or that the word _flemyng_, in this passage, means _banishing_, but rather _defeating_, _daunting_, _dismaying_, in which sense it occurs more than once in Layamon; thus, vol. ii. p. 410.:-- "Thine feond _flæmen_ & driven hem of londen." The general sense of the word is, however, _to expel_, _to drive out_, and not _to enclose_, as Alexander is said to have done the Gog and Magog people, by his iron, or rather bituminous, wall. Now those who were at Dulcarnon, or _in a Dilemma_, might well be said to be defeated or dismayed. Let us hope that some oriental scholar among your correspondents may be able to indicate where the word is to be found in some Arabian expositor of logic or dialectic, &c., and thus set the question entirely at rest. Are we never to have an edition of Chaucer worthy of him, and creditable to us? Had our northern neighbours possessed such a treasure, every MS. in existence would have been examined and collated, and the text settled. His language would have been thoroughly investigated and explained[3], and every possible source of elucidation made available. May we not hope that the able editor of Layamon and Wickliffe will yet add to the obligation every lover of our early literature owes to him, an edition of our first great poet, such as his previous labours have shown that he is so well qualified to give?
