Describe symbolism in The Damnation of Theron Ware by Harold Frederic

Frederic uses snakes as a symbol of temptation. Celia, for example, refers to Forbes and Ledsmar as resembling "gorged snakes". This symbol is used again when Ware finds himself drawn to Celia's music in the church. He feels as if he is being drawn against his will, "like fascinated bird to python."
