Essentially composed of concrete, but also includes iron and marble. The main body of concrete consists of several faces that in themselves act as small canvases. Each face is a small box of hard but elegant aesthetic, which shows the richness of this simple material when being worked in formwork. The upper face gives us an entirely different aspect of the material: we can read the traces of the artist's hands on the surface, and capture in the cracks the tensions formed by the iron rod which, like an arrow, breaks the horizontal plane and seems to store in Its interior part of the energy that employed durnate its placement. The marble corner fills the void created by the concrete spill, one of the most characteristic elements of the piece, which offers us another aspect different from the material of the previous ones. A rounded and polished surface that in a relaxed way frees us of all the tension, energy and concentrated force in the rest of the work.
