Piero Dorazio is considered a completely original and coherent figure in Italian art and one of the leading representatives of international op art. The three works exhibited here, Blue Call, Ascolto and Semperverde 2, are among the most representative examples of his textures from the early sixties: dense networks of color which, transforming into luminous filters, create elaborate optical games. The surface becomes a field of chromatic activation thanks to the superimposition of an intertwining of crossed lines - irregular and undefined - on a background given by glazes, working in each work on different shades of colors. Dorazio's painting was not born as a composition made of signs but, in the same way as Castellani, as a structure whose points have neither a temporal succession nor a spatial hierarchy. This is also demonstrated by the double signature (at the bottom and, overturned, at the top left) of Evergreen 2. The work does not have a line, it has no top or bottom, it has no contours, it is potentially infinite. What Dorazio creates is a “timeless” plot, immobile but dynamic. The movement is given by the light, which radiates from the texture itself. Dorazio's art of the 1960s is characterized above all by the bursting of color on the canvas, a characteristic that the artist will continue throughout his subsequent production. Dorazio thus experiments with the combination of multiple colors and studies the effect that the composition and decomposition of the same gives to the work, based on the morphology of the stroke and the flexibility or linearity of the stroke. The main accusation leveled at his painting in recent years is that of decorativism - and actually often the distinction lies in the subjective perception of the work and in the quality of execution.
