"Ensō, the symbol of the circle, fascinated me in particular because of what it represents: enlightenment, completeness, everything, nothingness. At that point, trying to give three-dimensionality to that gesture was a natural step for me'. This is how Enzo Catellani, founder in 1989 of Catellani&Smith, a brand of "rigorously handmade" artisan lamps, recounts the origin of Ensō, the latest addition to the catalogue of a company that has always been in search of a distinctive sign, capable of lighting up a singular trace in the lighting panorama, made to remain in time.
