A record of an archeo echo. 3 million Hertz per second, 5 minutes, and 7 billion years in 2023. Ultrasonic frequencies of sound waves, pulsating off the surface of a solid rock of translucent white onyx, submerged in water, sunken again below the sea, recomposing the potential and spatial distances by returning to a deep time, as the membrane of a body. Sound becomes visible as the abstracted, yet anthropomorphic frames translate the traces into a soundtrack of stratigraphic depths. A fluorescent yellow light pierces a fissure, oscillating a horizontal plane as the measure of tempo. The echo’s record of the sublime geological landscape rotating on its own axis, is suspended in time, collapsing the memory of the material, but only for a nanosecond. Sound travels faster underwater.
