During this same night a phenomenon appeared in the heaven, which powerfully affected the imagination of the pilgrims. An eclipse of the moon produced all at once the most profound darkness, and when she at length re-appeared she was covered with a blood-red veil. Many of the Crusaders were seized with terror at this spectacle; but those who were acquainted with the march and movements of the stars, says Albert d’Aix, reassured their companions by telling them that the sight of such a phenomenon announced the triumph of the Christians and the destruction of the infidels. By the break of day, on the 10th of June, 1099, the Crusaders ascended the heights of Emmaus. All at once the holy city presented itself to their eyes.[155] The first who perceived it exclaimed together, “_Jerusalem! Jerusalem!_” The rear ranks rushed forward to behold the city that was the object of all their wishes, and the words, “_It is the will of God! It is the will of God!_” were shouted by the whole army, and resounded over Mount Sion and the Mount of Olives, which offered themselves to the eager gaze of the Crusaders. The horsemen dismounted from their horses, and marched barefooted. Some cast themselves upon their knees at beholding the holy places, whilst others kissed with respect the earth honoured by the presence of the Saviour. In their transports they passed by turns from joy to sadness, and from sadness to joy. At one moment they felicitated themselves with touching the last term of their labours; and then wept over their sins, over the death of Christ, and over his profaned tomb; but all renewed the oath they had so often made to deliver the holy city from the sacrilegious yoke of the Mussulmans. History furnishes very few positive notions of the foundation and origin of Jerusalem. The common opinion is, that Melchisedec, who is called king of Salem in Scripture, made his residence there. It was afterwards the capital of the Jebusees, which procured it the name of the city of Jebus. It is probable that from the name of Jebus and that of Salem, which signifies _vision_, or _abode of peace_, was formed the name of Jerusalem,[156] which it bore under the kings of Judah.
