Cyanometer Postcards

“These postcards were made for the 13th Architecture Venice Biennale, drawing on Horace-Bénédict de Saussure's cyanometer, a tool invented in 1789 for measuring the blue of the sky. Besides the blue, Ruiz-Tagle makes variations for grading shades of sunset and polluted skies. My pal @Abbey Nova sent me one to add to my collection (I have another cyanometer by Dust Collective); it's an excellent little gift for a sky-watching friend.”

“Share the sky above with someone far away. Artist Macarena Ruiz-Tagle created these conceptual art postcards as part of the 13th Architecture Venice Biennale. Hold the Cyanometer or Sunset postcard to the sky and peer through the Cyanometer, mark the corresponding hue, and share a thought or two before dropping it in the mail. Horace-Bénédict de Saussure, a Swiss naturalist (1740-1799), is credited with inventing the Cyanometer in 1789 during his expeditions in the Alps.”

“I’d send these across our hallway to my daughters so we could lay in the grass + do this together🌈”

“me + this lying on the grass for several hours? we’d be unstoppable”
