Narcissus and Echo are the primary characters in the classic Greek tragedy enacting this issue. They have relevance due to the increase in narcissism with its singularity, isolation, and inability to be intimate. The themes of the Greek myth illustrate one-sided love turning to psychological and physiological deterioration, and death. These mythological figures demonstrate parts of the personality applicable beyond the strictures of gender and binary thinking. Echo and Narcissus each represent loss of love and lack of connection to oneself and others. This is part of what obstructs the process of love in modern relationships.
