This book explores the diachronic development of processional oracles in ancient Egypt, covering textual records from the New Kingdom through the Graeco- Roman period (c. 1550 BCE - 400 CE). Oracles in Egypt were characterized by purposeful, linguistically-formulated solicitations by humans, often in the form of specific questions. Inquiries were presented to a god through established ritual mechanisms that yielded answers to petitioners more or less directly from the deity. Some of the most characteristic (and longest-lived) types of oracles in Egypt were processional oracles, which took place during divine festivals in which an image of the god was brought out in procession and carried along a sacred route.
