The Parthenon’s structure suggests a thought-out design particularly attentive to light. This includes the orientation of the building towards the rising sun, the placement of windows, the use of barriers and grilles, the translucent marble ceilings, the skylights, and even ‘reflective’ pools of various liquid. These are all devices that, alongside bright materials, may have been used to enhance the experience of visitors to the temple and their encounter with the colossal gold and ivory statue of the goddess Athena. To test the validity and the effect that each of these purported design strategies produced, this article proposes an experiment using advanced 3D digital technologies, along with physically based lighting simulations, to recreate the ambient and architectural conditions that existed in the original temple design. The results suggest that this temple, contrary to long-standing beliefs that imagined the interior as a ‘bright marble space’, was generally quite dark and dim. The subsequent discussion and concluding remarks suggest that the illumination of the chryselephantine statue’s materials through the glow of a lamp, and on rare occasions from the sun, probably represented the pinnacle of the viewing encounters.
