Sound and hearing play a crucial role in the conceptualisation and perception of divine entities, cultic places, and ritual processes. Sound phenomena can evoke religious experiences, structure ritual communication and stimulate desired emotional responses, whilst exposure to certain resonance frequencies can affect the human body, thereby influencing one’s perceptions and states of consciousness. This essay analyses the Dodonean soundscape, exploring the potential affect of the various sonic experiences in relation to the process of consultation. In addition to the diverse sensory input from the natural environment, which in the case of Dodona is crucial, as it can be surmised from the traditional accounts of the oracular oak, special consideration is given to the chalkeion of Dodona, a remarkable sonic installation that offered one of the most unusual auditory experiences to the pilgrims. Based on the symbolic and sound properties of the chalkeion, it is possible to suggest that the soundscape at Dodona invited a form of ecstasy or meditation, with the potential to alter the focus of attention and consciousness, thus allowing for new forms of knowledge to become available.
