|| Tortoise scales, elephant skins, sometimes even dinosaur scales, this is how we call the polygonal networks on the sandstone of the Fontainebleau massif. We find these mineral tortoise scales throughout the world and beyond (on Mars, polygonal structures on sandstone were observed by the robot Curiosity).

 

|| The "skin" of this sandstone (the superficial layer harder than the interior of the rock) contracts as a result of thermal changes and cracks. This true crazing generates a network of pentagons and hexagons that erosion will carve, round and soften.

A stone that is cold, shrinks, melts, dissolves ...

 

|| The result is a myriad of shapes with natural ergonomics, which would have been made for gripping. A illustrated the legend which consider that the sandstone boulders of Fontainebleau are the cradle of climbing. These boulders and their "emblematic" natural climbing hold in polygonal networks are still, at the present time, "worshipped" by the climbers of the whole world.

 

 

|| Peaulygone was born from a boulder of Fontainebleau, its network of polygonal scales was scanned and reshaped in 3D, then cast in bronze. Designed as a candlestick, it is thought to emerge from a plane surface. It brings to light and in contrast this millenary crazing shapping made by this "Great Craftsman" that is the nature. It is a "photographic" gesture that freezes a state of "mineral dissolution". ||
