Spectrum 14 is a calibrated array of prisms that cast a dazzling display of luminous color across the Museum’s rotunda. Bands of spectral light traverse the space in relation to the sun, which follow a slightly different arc through the sky every day. Over time, Ross’s work changes in response to Earth’s rotational orbit, connecting us to the premodern experience of astronomical observation and calculation that defined cycles of days, seasons, and rituals.

This project was commissioned for PST ART as part of the exhibition Lumen: The Art and Science of Light. This is the second “Rotunda Commission,” a series of art installations inspired by the Getty Museum’s collection, architecture, and site.

This exhibition is presented in English and Spanish. Esta exhibición se presenta en inglés y en español.
