Note 87 — THE GIAOUR.
Reading edition
{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.]
