As a rule, the introduction of scripts usually contains basic hints that through forthcoming lines will be explored and developed in more detail. The same is true about the introduction of Plato’s Politeia or Republic Book One. The mentioned dialogue is about the constitution of polis in philosophical manner, but it does begin with a religious narration about a civic foreign religion and gradually develops into the philosophy of city-state. This occasion makes it necessary to have a deep look at this phenomenon and see what implicit points are contained. In this regard, it seems that the pair hiera / hosia can provide a suitable conceptual framework for ordering and understanding of the introduction.
