Giorgio Griffa (Turin, 1936), artist, has been a leading figure on the international arts scene and one of the most respected contemporary painters ever since the 1960s. In 1968 he abandoned the figurative style to evolve a new language, used throughout his career as a painter: the canvas is peopled with elementary signs in water-based acrylic paint applied to the raw surface (jute, hemp, cotton or linen), which is left “bare”, without a frame. His works are vibrant and free, fixed directly to walls with small nails which only support their top edges; subdivided into cycles, they are known as an “unfinished constant”, with a stylistic language based on repetition, which acquires the rhythmic consistency of the iconic signs and expressive grammar of writing.
