Isabelle knew not what to do; for, on being informed by her father of the fate he had destined for her, her heart forsook her, and her spirit was bowed to the dust. Nowhere could she rest, like the Thracian bird that knoweth not to fold its wings in slumber--a cloud had fallen for her over the fair face of nature--and, instead of retiring to her couch, she wandered about weeping, under the midnight stars, on the terrace on the house-top--wailing over the hapless fate, and calling on death to come and take her from her sorrows. At morning she went forth alone into the garden; but neither could the golden glow of the orange-trees, nor the perfumes of the rosiers, nor the delicate fragrance of the clustering henna and jasmine, delight her; so she wearied for the hour of noon, having privately sent to Demetrius, inviting him to meet her by the fountain of the pillars at that time. Poor Demetrius had, for some time, observed a settled sorrow in the conduct and countenance of his beautiful Isabelle--he felt that some melancholy revelation was to be made to him; and, all eagerness, he came at the appointed hour. He passed along the winding walks, unheeding of the tulips streaked like the ruddy evening clouds--of the flower betrothed to the nightingale--of the geranium blazing in scarlet beauty,--till, on approaching the place of promise, he caught a glance of the maid he loved--and, lo! she sate there in the sunlight, absorbed in thought; a book was on her knee, and at her feet lay the harp whose chords had been for his ear so often modulated to harmony. He laid his hand gently on her shoulder, as he seated himself beside her on the steps; and seeing her sorrowful, he comforted her, and bade her be of good cheer, saying, that Heaven would soon smile propitiously on their fortunes, and that their present trials would but endear them the more to each other in the days of after years. At length, with tears and sobs, she told him of what she had learned; and, while they wept on each other's bosoms, they vowed over the Bible, which Isabelle held in her hand, to be faithful to each other to their dying day. Meantime the miser was making preparations for the marriage ceremony, and the father of Isabelle had portioned out his daughter's dowery; when the lovers, finding themselves driven to extremity, took the resolution of escaping together from the city. Now, it so happened, in accordance with the proverb, which saith that evils never come single, that, at this very time, the city of Damascus was closely invested by a mighty army, commanded by the Caliph Abubeker Alwakidi, the immediate successor of Mahomet; and, in leaving the walls, the lovers were in imminent hazard of falling into their cruel hands; yet, having no other resource left, they resolved to put their perilous adventure to the risk.
