The equinox is the moment in the year at which the sun is located directly above the Equator, its light falling perpendicular to the Earth’s axis, making the length of day and night equal across the planet. Many pre-Hispanic cultures erected buildings, observatories, and ceremonial sites that took into account the sun’s position during the annual solstice and equinox. In Andean culture, the equinox is a celebration of harvest, the moon and female spirit, and sets in motion a process and ritual of purification.

Inspired by this celestial phenomenon, the exhibition began precisely at the start of the Southern Hemisphere’s vernal equinox: September 22 at 17:02 hours. The exhibition presented a minimal, site-specific intervention based on the conditions that characterized Galería Tajamar’s space: its geometry, transparency, and the relationship between its interior and exterior.

From then until October 27, the gallery was used as an instrument of observation: regarding everyday physical phenomena as imperceptible as the constant and cyclical movement of the Earth. In order to do this, one of the gallery’s large windows was partially covered with a transparent holographic plastic that, like a prism, diffracted the light entering the exhibition space and made visible the color spectrum that constitutes sunlight. The intent was to visibly configure an event that would bring a celestial phenomenon from nature into the interior of a space; one that was both enclosed and transparent.

Equinox was an invitation to explore our everyday relationship with a larger planetary geometry.
