While verbally transmitted fairy tales express universal human concerns, the literary fairy tale, the written creation of an individual author, permits a psychodynamic understanding of the writer. The little mermaid's willingness to undergo the pain and mutilation involved in the loss of both her tail and was voice in order to become a mortal and marry a prince has been regarded as illustrating problems in female sexual development. However, a review of Hans Christian Andersen's biographical data indicates that the story also represents his unconscious homosexual conflicts and supports Freud's concept of the role of castration anxiety in the negative Oedipus complex.
