Perhaps the poet desired to show us here the extremest imaginative force of hate and cruelty--not in a mortal being, because that would repel us, but in an immortal being, in whom such emotion can only inspire fear. Emotionally, the poet's conception is of the Middle Ages, but the tradition is incomparably older; we can trace it back to ancient Assyrian beliefs. Coming to us through Hebrew literature, this strange story has inspired numberless European poets and painters, besides the author of "Eden Bower." You should know the story, because you will find a great many references to it in the different literatures of Europe. Briefly, Lilith is the name of an evil spirit believed by the ancient Jews and by other Oriental nations to cause nightmare. But she did other things much more evil, and there were curious legends about her. The Jews said that before the first woman, Eve, was created, Adam had a demon wife by whom he became the father of many evil spirits. When Eve was created and given to him in marriage, Lilith was necessarily jealous, and resolved to avenge herself upon the whole human race. It is even to-day the custom among Jews to make a charm against Lilith on their marriage night; for Lilith is especially the enemy of brides. But the particular story about Lilith that mostly figures in poetry and painting is this: If any young man sees Lilith, he must at once fall in love with her, because she is much more beautiful than any human being; and if he falls in love with her, he dies. After his death, if his body is opened by the doctors, it will be found that a long golden hair, one strand of woman's hair, is fastened round his heart. The particular evil in which Lilith delights is the destruction of youth. In Rossetti's poem Lilith is represented only as declaring to her demon lover, the Serpent, how she will avenge herself upon Adam and upon Eve. The ideas are in one way extremely interesting; they represent the most tragical and terrible form of jealousy--that jealousy written of in the Bible as being like the very fires of Hell. We might say that in Victorian verse this is the unique poem of jealousy, in a female personification. For the male personification we must go to Robert Browning.
