In 1956, when he had just turned 20, he started producing Metaesquemas. This series comprises over 400 works, and consists of methodical exercises, mostly painted in gouache on cardboard, favoring experiments with colors (black, red, yellow, blue and green), geometric abstract shapes and space.

In his last works for the series, produced in 1957 and 1958, the artist explores, above all, rectangles and trapezoids, both in plain color and in shapes composed of thick colored outlines. These geometric elements are frayed, making them malleable, which adds movement to the compositions. However, the extraordinary and, in fact, “danceful” aspect of these shapes is seen when they touch each other slightly, and when they are arranged asymmetrically, thus creating vibrations and rhythms, harmony and mismatches.
