It is thus that the lyric poetry of one age affects, or finds its echo in, that of another, but in this particular case it is, of course, a natural thought that true love must survive the grave. There is a mystical union between the two souls, which death cannot end. Here, again, we meet the close connection between love and mysticism, which lies at the root of all deep love poetry. But we must attend to the literary history of the thought for a moment longer. Moses ibn Ezra, though more famous for his Synagogue hymns, had some lyric gifts of a lighter touch, and he wrote love songs on occasion. In one of these the poet represents a dying wife as turning to her husband with the pathetic prayer, "Remember the covenant of our youth, and knock at the door of my grave with a hand of love." I will allude only to one other parallel, which carries us to a much earlier period. Here is an Arab song of Taubah, son of Al-Humaiyir, who lived in the seventh century. It must be remembered that it was an ancient Arabic folk-idea that the spirits of the dead became owls. Ah, if but Laila would send me a greeting down of grace, though between us lay the dust and flags of stone, My greeting of joy should spring in answer, or there should cry toward her an owl, ill bird that shrieks in the gloom of graves. C.J.L. Lyall, writing of the author of these lines, Taubah, informs us that he was the cousin of Laila, a woman of great beauty. Taubah had loved her when they were children in the desert together, but her father refused to give her to him in marriage. He led a stormy life, and met his death in a fight during the reign of Mu'awiyah. Laila long survived him, but never forgot him or his love for her. She attained great fame as a poetess, and died during the reign of 'Abd-al-Malik, son of Marwan, at an advanced age. "A tale is told of her death in which these verses figure. She was making a journey with her husband when they passed by the grave of Taubah. Laila, who was travelling in a litter, cried, By God! I will not depart hence till I greet Taubah. Her husband endeavored to dissuade her, but she would not hearken; so at last he allowed her. And she had her camel driven up the mound on which the tomb was, and said, Peace to thee, O Taubah! Then she turned her face to the people and said, I never knew him to speak falsely until this day. What meanest thou? said they. Was it not he, she answered, who said Ah, if but Laila would send a greeting down of grace, though between us lay the dust and flags of stone, My greeting of joy should spring in answer, or there should cry toward her an owl, ill bird that shrieks in the gloom of graves.
