This work documents the first stage of a monumental land-art installation by Michel Comte on the site of the ancient Turkish city of Harran, due for completion in 2030. Located in Upper Mesopotamia about 20km from the present Syrian border, Harran was a vital trading post and lies at the heart of civilisations beginnings: archaeological remains like those of nearby Göbekli Tepe show the earliest cultivation of crops and domestication of animals, and the first connections between religion and architecture. Populated by the Sabians, a community of star worshippers, Harran boasted an outstanding view of the constellation of Orion; here was the worlds first observatory, and in the ninth century AD the city become a leader in the Arabic world for the production of celestial globes.
