There are several symbols in the poem "Christabel" by Samuel Taylor Coleridge. The first, and most obvious, symbol is that of light and dark. Light symbolizes good and dark evil. The lamp helps the reader see this. Christabel lights the lamp, and Geraldine cowers from it. Another symbol in the poem is the snake. The attackers in the poem are described as having "reptile souls". This snake symbol is also a Biblical allusion to the serpent and evil. Coleridge's symbols are integrated seamlessly into his work. His symbols are as important as his plot.
