Mythical criticism of literal and/or art works may be considered as one of the most important branches of criticism. In this respect, the idea of monomyth of Joseph Campbell, thanks to its distinctive feature, has been always referred to by many researchers in art, literature as well as linguistics. Campbell maintains that myths, in the beginning, follow architypes in terms of form, content and structure. In different cultures, however, they are transformed into different forms in the course of time. Here, a hero (more technically known protagonist) plays a major role in universal architypes. Religious myths, among other pivotal ones, have been represented into diverse derivations. Accordingly, the story of Moses, the Prophet, with its narrative dimensions, is a prime example of a religious myth. In the present study, the story of Moses depicted onto a rug ground has been read mythically. The main question here is how Campbell’s idea of monomyth can help us to read the course of the story from the start to the end of the journey as well as the role of the antagonist, the Moses, so that deeper layers of spiritual transformation of Moses can be appreciated more tangibly. In this story, Moses, the Prophet, as a religious mythical hero, has been chosen to fulfil his divine mission. Campbell holds that the journey of nearly all heroes may be formulated in three major pillars namely, Separation (departure), being Honored and Return. Findings: According to Joseph Campbell’s idea of monomyth of Joseph Campbell, the form and content of the story of Moses, as a religious myth, can be safely put in those mythical stories enjoying primal architypes. Along with other symbolic elements and architypes, Moses, as the hero of the story, passes the three phases successfully one after another, in his own manner, to accomplish his mission. This study is essentially qualitative. The data were gathered mainly from library sources and then were analyzed descriptively.
