Ethos Lithos

Ethos Lithos is a five-surface projection room in which visitors walk through the interior state of a flow model trained to transport between the Pantheon's measured geometry and 269 passages written about the building across nineteen centuries. The model's learned path from stone to language is a world model at the scale of one building, and the room makes it walkable: the latent space is projected onto the dome's own coffer coordinate system, and a visitor's position, the only input the work receives, becomes the model's query point. That crossing does not happen at the midpoint: the model holds the building's geometric identity for most of the journey before yielding to language, a measured asymmetry the room's climax is built around.
