Beginning in the late fourth century, a new type of stone stelae appearedamong indigenous communities for religious purposes. Nevertheless, different from their preceding counterparts which recorded either governmental decrees or biographical sketches, these stelae, in terms of epigraphical sources, inscribed only a section of dedicatory prayers, informing us of the wishes of the lay patrons of stelae at that time. Such a transformation in functional context is significant in a way that it implied not only the zeitgeist of the time but also a heterogeneous interpretation of stone as a medium of representation, or more specifically, a rediscovery of stone as a functional medium in a religious framework. Despite the fact that the rationales behind the transformation are complicated in nature, this paper aspires to propose a new dimension to the discussion by referring directly to the stele inscriptions. In light of the fact that stone was no longer considered as a material documentary agent but a transparent narrative medium, through which patrons could convey their wishes directly, probably by means of chanting and praying, to celestial deities in accessing the divine realm. By adopting such an approach, this paper contends that the symbolic interpretation of stelae should be perceived as a crucial factor accounting for the functional transformation of the medium.
