Dee's dream is not taken directly from literature, but does contain elements from several important works. Shakespeare's Julius Caesar forms the setting, the three pale women are another iteration of the Fates or the witches from Macbeth, and Sophocles' Oedipus Rex (and associated theories in psychology) contribute to the dream Dee relates to the women.
