Rotella used oil paint at the beginning of his career, first with a figurative intent, then moving on to abstract-geometric paintings characterized by basic colors. After a creative crisis that led him to the invention of décollage and development of different techniques in following years, from 1984 Rotella get back to the pictorial medium in a series of acrylic paintings. The return to painting sets off a renewed energy at the base of the sovrapittura technique.
