Polyurethane foam, flint

Variable dimensions

Hundreds of flint fragments are methodically stuck onto one side of a large green foam parallelepiped made for floral arrangements. This vertically-standing sculpture by Hubert Duprat takes its name, Tribulum, from an ancient agricultural instrument pulled by an animal to separate grains from straw. This contemporary version becomes a mysterious decorative object with surprising optical illusions.

A revisited archaeological reconstruction, Tribulum is the result of research linking palaeontology and craftsmanship. Flint debris was painstakingly cut using prehistoric methods before being carefully placed in fragile foam. The resulting poetic object combines different techniques and knowledge, attesting to Duprat's multidisciplinary, complex work.

Tribulum was shown for the first time by the Pinault Collection in 2015 at the exhibition "Slip of the Tongue" at the Punta della Dogana.
