Ancient Etruscan tombs carved more than 2,400 years ago may have been designed to shape human perception, according to a new study pairing artificial intelligence (AI) with sound analysis to examine burial chambers in Italy.
The research, published in the Journal of Archaeological Method and Theory, looked at two Etruscan tombs in Tarquinia dating to the fifth century B.C. and found their builders may have used light, sound and imagery to guide how visitors felt and moved inside.
The study was conducted by Maurizio Forte of Duke University and Jacqueline K. Ortoleva of the University of Oxford. The researchers examined the “Tomb of the Rooster” and the “Tomb of the Blue Demons,” both located in the Monterozzi necropolis.
They used computer vision software to map where the eye is naturally drawn inside each tomb, then paired that data with acoustic recordings taken with a speaker and microphone placed at several points inside the chambers.
Etruscan tombs reveal clues about human perception design
The findings show the two tombs created very different experiences. Ortoleva said the Tomb of the Rooster is small, and its narrow entrance passage limits sound, keeping noise from building up inside the chamber.
Its wall paintings, including a scene showing a dancer with a masked performer, draw attention toward one main scene, according to the study. That design likely kept visitors calm and focused, similar to a state of quiet, steady attention.
By contrast, the Tomb of the Blue Demons is much larger and holds sound for several seconds, a delay researchers compared to what is measured inside large cathedrals.
The tomb includes a wall painting of a blue demon that stood out sharply in the visual mapping, pulling the eye with force. Forte said the combination of a startling image and a confusing echo may have overwhelmed visitors, disrupting their sense of direction and hearing.
Blue Demon tomb triggers sensory overload and disorientation
The study also draws on neuroscience to suggest how the brain may have responded inside each space. Researchers said the pattern of sound and imagery in the larger tomb could have moved visitors from alertness to fear, and finally into a trance-like state near a banquet scene on the rear wall.
In the smaller tomb, the design appears to support calm, steady observation rather than emotional disruption, the study found.
Researchers noted both tombs were likely visited repeatedly by families honoring the dead, not used only for burial. They said the findings suggest ancient builders understood how architecture could shape emotion and memory more deeply than previously believed.
The authors added that more tombs must be studied to gauge how widespread this kind of sensory design was across the ancient Mediterranean.
