Cyanometer Postcard
Republic of Common Ground in collaboration with Gúnther Vogt Landschaftsarchitekten Zurich 13th Architecture Venice Biennale

The Cyanometer Postcard refers to the variations of blueness when looking at the sky on a certain moment, to write this information down and share it with the receiver. It seeks to communicate senders and receivers across the latitudes of the world when thinking about the sky. Project collaboration with Case Studio Gúnther Vogt Landschaftsarchitekten Zurich. Available for free at the Kiosk on the corner of Via Garibaldi and Riva dei Sette Martiri, San Marco, Venice, Italy.
Horace-Bénédict de Saussure (Swiss Naturalist, 1740- 1799) is credited to have invented the Cyanometer in 1789 during his trekking expeditions to the Alps. Alexander von Humboldt also used the Cyanometer on his journey in Latin America (1799-1804).
