Achille Perilli was born in 1927 in Rome. He draws and paints attending, together with Dorazio, the studio of the painter Aldo Bandinelli. He attends high school, visits museums, discovers the art of the twentieth century through the writings of Margherita Sarfatti, an essential figure of the Italian twentieth century. In 1946 he met Renato Guttuso, attended his studio and came into contact with Accardi, Attardi, Consagra, Sanfilippo and Turcato, forming with them, the following year, the "Forma 1" group, of which he directed the manifesto for an art "of the pure form". The group "Forma1" exhumes the term "aniconic art" from the Greek ikona, image, preceded by a negative preposition (alpha privative), which expresses a non-figurative, non-referential form of expression that cannot be related to any known image, without any reference to forms real or natural.
