Patience, discipline, effort, concentration, and perseverance are words that nurture Rodrigo Spinel's artistic practice. These are concepts and moral values that allude to hard work, and dedication, reflected in the artist's attraction to objects that exhibit intense labor of repetition, such as banknotes and stamps drawn line by line in their original die, or in the walls built by summing up hundreds of bricks laid one by one.

The figure of the mason is a central referent in which Spinel recognizes these values, and using it as a simile between the effort of building a wall brick by brick, and the resistance to build a drawing line by line. As the mason, by repeating so many times the simple gesture of the straight line, he builds up complex structures in which the time deposited in each piece is inevitably evident.

Value is another word that appears frequently in his practice. In the series Currency , he wonders about the subjective value given to objects, such as stamps, comics, or artworks, reproducing them with his meticulous drawings and resignifying them with the time of each line. In the series El papel moneda es blanco, he exposes the value, perhaps lost, of the symbols that appear on bills, by drawing fragments on the Surface.

Rodrigo Spinel's background as an architect is reflected in a drawing close to the languages of planimetry and axonometries, where he explores the volumetric possibilities that appear in the accumulation of lines that can be seen in the solo exhibition Volúmenes de la Línea at La Balsa Medellín. But also in the way of approaching a subject by abstracting parts and examining them under a magnifying lens to find the details.
