1. The Moslem legend of Mahomet’s nocturnal journey and ascent to the spheres of after-life originated and developed like most religious legends. Born of a brief passage in Revelations, in its very obscurity it defied theological interpretation. But what baffled the sages in their agnosticism kindled the imagination of the faithful masses, and the details of a story founded upon the sacred text were readily conceived.

One brief allusion only appears in the Koran: “Praised be He [the Lord]”—runs the first verse of the seventeenth chapter—“who called upon His servant [Mahomet] to travel by night from the sacred temple [of Mecca] to the far-off temple [of Jerusalem] whose precinct We have blessed, in order to show him Our wonders.”

2. The mysterious allusion seems from the first to have aroused the curiosity of pious Moslems. A rich crop of legends sprang up as if by magic. The vivid imagination of the East had been fired, and the myth of the nightly journey was soon clothed with a wealth of detail and set in a wonderful variety of episode and scenery.

The entire records of the evolution of the legend in all its ramifications would fill volumes. Around an insignificant verselet of the Koran a plot was woven, and the story developed in the form of hadiths or traditions of the Prophet, who was supposed to describe the wonders he saw on that memorable night. In the following pages an endeavour has been made to lay before the reader some of the principal versions extant. These have been divided into three cycles or groups, which begin with the simple, fragmentary types, and end with those in which Oriental fantasy reaches its climax.
