Sol LeWitt's work is characterized by using different techniques that allowed him to find the right compromise between perceptual and conceptual quality, between the simplicity of geometric order and the search for beauty and intuitive creation. 

His artistic research is developed through his famous wall drawings and geometric structures. He deconstructed the concept of authorship related to the realization of the work, recognizing the preeminence not to the hand, but to the mind that conceived it. In parallel the artist has produced many works on paper throughout his career. 

The exhibition focuses on works never exhibited before and executed between 1992 and 2005, a period in which LeWitt decided to devote himself more to painting. The technique he uses is gouache on paper, water-based opaque painting, in which he has been fascinated since the 1980s.  

His studies led him towards the definition of less rigid forms, articulated by the creation of spatial depths. The result is abstract works composed of free-flowing fluid brushstrokes. 

The artist thus transforms ideas into visual embodiments, visible manifestations of systems and rules that creatively mix each other, giving rise to a multitude of combinations. Lines, shapes, colors and volumes establish a subtle balance between thought and form, between order and disorder, authorship and anonymity. His work is articulated through concrete mental and visual structures in a constant search that has allowed him to constantly renew himself. 

The titles of the exhibited works recall the technique described above: Brushstrokes, Horizontal Lines and Irregular Form. As horizontal lines in a virtuous superimposition create a three-dimensional perception from the flat surface of the sheet, so the irregular shapes defined by contrasting hues give to the form a prominent perceptual condition. His works thus reveal themselves as structures that come alive through the idea, defying the addiction of the artist to his manual skill.
