During the 1970s, Rodolfo Aricò along with Giorgio Griffa and Claudio Olivieribecame a point of reference of analytical painting, an artistic movement that is separated from the constraints of reality, and that calls into question the foundations of painting. This creates an intimate reflection on the role of the artist. Rodolfo Aricò reflects his humanistic theme in his designs and his archetipi storici. Space for the artist became a place of reflexion, he uses a bare style which is then filled paint which makes the area of geometric matter. To spread the colour, the artist uses a pump, usually copper coated, to spray the paint on the canvas. This action gives the impressions of colourful raindrops, in fact the colours are pulverized and mixed with water and PVA glue. However, the act is not completely random; the artist takes into account the different glazes, obtained from the use of the amount of PVA glue, or by the proximity of the sprayer to the canvas. The eye, in fact, perceives different shades of colours: lighter/darker and more/less dense patches. The way Rodolfo Aricò sprays and diffuses the colour is a scared act, an action linked to the emotion, the feeling which pervuades the painter. Colour allows the artist to transmit the emotion to the viewer, also through the geometric structure, thanks to the assembly technique of more paintings – mounted on shaped frames – which creates dynamic relationships. The effect is surprising; at first glance, his work is an impression of immobility. In 1964 he participated in theXXXII Venice Biennale and returned there again in 1968 with his own personal room. Again in Venice in 1974, Rodolfo Aricò was invited to a retrospective at the Palazzo Grassi, where he presented large-scale works in which we can see the structural evolution and objective of his work from 1968 onwards. In the following years both the critics and prestigious galleries invited him to exhibit until the last years of his production.  In 2013, Rodolfo Aricò came to present the work Post War Protagonisti Italiani curated by Luca Massimo Barbero at the Guggenheim museum in Venice.The works of Rodolfo Aricò of the 1960s and 70s is recognised together with Lucio Fontana, Piero Dorazio, Enrico Castellani and Paolo Scheggi. Today in Milan we can find his works in the Gallerie d’Italia and Sala Napoleonica in the Brera Academy and in the Rodolfo Aricò archives at the Invernizzi Gallery and theLorenzelli Gallery
