Sir Richard Burton (Arabian Nights, S.N., iii. 440) gives the following résumé of the conflicting legends: "Jám-i-jámshid is a well-known commonplace in Moslem folk-lore; but commentators cannot agree whether 'Jám' be a mirror or a cup. In the latter sense it would represent the Cyathomantic cup of the Patriarch Joseph, and the symbolic bowl of Nestor. Jamshid may be translated either 'Jam the bright,' or 'the Cup of the Sun;' this ancient king is the Solomon of the grand old Guebres."
Fitzgerald, "in a very composite quatrain (stanza v.) which cannot be claimed as a translation at all" (see the Rubáiyát of Omar Khayyaām, by Edward Heron Allen, 1898), embodies a late version of the myth—
"Iram is gone and all his Rose,
And Jamshyd's sev'n-ringed Cup where no one knows.">[
[87] {109} Al-Sirat, the bridge of breadth narrower than the thread of a famished spider, and sharper than the edge of a sword, over which the Mussulmans must skate into Paradise, to which it is the only entrance; but this is not the worst, the river beneath being hell itself, into which, as may be expected, the unskilful and tender of foot contrive to tumble with a "facilis descensus Averni," not very pleasing in prospect to the next passenger. There is a shorter cut downwards for the Jews and Christians.
[Byron is again indebted to Vathek, and S. Henley on Vathek, p. 237, for his information. The authority for the legend of the Bridge of Paradise is not the Koran, but the Book of Mawakef, quoted by Edward Pococke, in his Commentary (Notæ Miscellaneæ) on the Porta Mosis of Moses Maimonides (Oxford, 1654, p. 288)—
"Stretched across the back of Hell, it is narrower than a javelin, sharper than the edge of a sword. But all must essay the passage, believers as well as infidels, and it baffles the understanding to imagine in what manner they keep their foothold."
The legend, or rather allegory, to which there would seem to be some allusion in the words of Scripture, "Strait is the gate," etc., is of Zoroastrian origin. Compare the Zend-Avesta, Yasna xix. 6 (Sacred Books of the East, edited by F. Max Muller, 1887, xxxi. 261), "With even threefold (safety and with speed) I will bring his soul over the Bridge of Kinvat," etc.]
[88] {110} A vulgar error: the Koran allots at least a third of Paradise to well-behaved women; but by far the greater number of Mussulmans interpret the text their own way, and exclude their moieties from heaven. Being enemies to Platonics, they cannot discern "any fitness of things" in the souls of the other sex, conceiving them to be superseded by the Houris.
[Sale, in his Preliminary Discourse ("Chandos Classics," p. 80), in dealing with this question, notes "that there are several passages in the Koran which affirm that women, in the next life, will not only be punished for their evil actions, but will also receive the rewards of their good deeds, as well as the men, and that in this case God will make no distinction of sexes." A single quotation will suffice: "God has promised to believers, men and women, gardens beneath which rivers flow, to dwell therein for aye; and goodly places in the garden of Eden."—The Qur'ân, translated by E. H. Palmer, 1880, vi. 183.]
