This article explores the socioreligious background of the Shang dynasty oracle bone inscriptions from an unconventional perspective by analyzing the use of oracular language in epigraphic texts found on slightly later ritual bronze vessels. While this phenomenon has so far received little scholarly attention, the author argues that the cross-contextual occurrence of oracular terminology indicates a relationship between the two types of epigraphic texts and the social discourses from which they were created. Drawing on parallel passages in other bronze inscriptions, the author examines the precise meanings of the two most common oracular phrases and proposes that they belonged to a technical terminology that shared fundamental conceptual characteristics with later legal jargon. Addressing the communicative intention behind their use, the author points out that oracular language is generally placed in prominent positions in bronze inscriptions and appears in various highly ritualized and ceremonial interactions between humans and the ancestral spirits. Based on these observations, the author concludes that the bronze inscriptions support the view that the Shang dynasty oracle bone inscriptions were written for administrative and specialized purposes and were embedded in a much wider network of communication practices between humans and supra-human powers.
