The Promise is a 1-1 copy of a symbolic Cypress tree, planted by Theodor Herzl on his only visit to Palestine in 1898. In 1915, this tree was burned in an act of Turkish nationalism, and eventually cut after failed rescue attempts. During the 1948 war, the stump was kept safe by soldiers and chauffeured in armored vehicles before being returned to its original location and placed in a cage. Littwitz spent years convincing authorities to replace the cage and managing to create a 3D scan during the time it took for them to do so. The work was commissioned by Kunst Halle Sankt Gallen for an eponymous solo exhibition in 2017, and created at Kunstgiesserei St. Gallen.
