Dr. Mercy provides a guided tour through the sages of the monomyth known as the hero's journey. In narratology and comparative mythology, the hero's journey, or the monomyth, is the common template of stories that involve a hero who goes on an adventure, is victorious in a decisive crisis, and comes home changed or transformed. Earlier figures had proposed similar concepts, including psychologist Otto Rank and amateur anthropologist Lord Raglan. Eventually, hero myth pattern studies were popularized by Joseph Campbell, who was influenced by Carl Jung's analytical psychology. Campbell used the monomyth to analyze and compare religions.
