"At present, I am particularly excited by 'bad taste'. I have the deep feeling that there exists in the very essence of bad taste a power capable of creating those things situated far beyond what is traditionally termed 'The Work of Art'. I wish to play with human feeling, with its 'morbidity' in a cold and ferocious manner. Only very recently I have become a sort of gravedigger of art . Some of my latest works have been coffins and tombs. During the same time I succeeded in painting with fire, using particularly powerful and searing gas flames, some of them measuring three to four meters high. I use these to bathe the surface of the painting in such a way that it registered the spontaneous trace of fire."

“This period of blue monochrome was the product of my pursuit of the indefinable in painting which that master, Eugène Delacroix was able to indicate even in his day.”

“It was in 1947 that the idea of a conscious monochrome vision came to me.. .Pure, existential space was regularly winking at me, each time in a more impressive manner, and this sensation of total freedom attracted me so powerfully that I painted some monochrome surfaces just to 'see', to 'see' with my own eyes what existential sensibility granted me; absolute freedom! But each time I could neither imagine or think of the possibility of considering this as a painting, a picture, until the day when I said: Why not?”

“In 1946, when I was still an adolescent, I went and signed my name on the other side of the sky during a fantastic 'realistico-imaginary' voyage.”

“A bill for 20 grams of Pure Gold, for one painted area of sensibilized immaterial.”

“Dubbed as a Knight of the Order of Saint Sebastian, I espoused the cause of pure colour, which has been invaded by guile, occupied and oppressed in cowardly fashion by line and its manifestation; drawing in Art. I aimed to defend and deliver it, and lead it to triumph and final glory.”
