The Cuatro Elementos (Four Elements) series comprises works uniquely representing the four elements: water, fire, air, and earth. In this series, Antonio materializes symbols alluding to each component through his textiles, intertwining threads, and wool. To represent Air, Antonio was inspired by indigenous Mayan men's costumes, which use a figure in the shape of an X. This figure represents air and wind. He explains that air comes from one side and wind from the other side, and when they converge, they create a geometric figure, an X. To represent the fire, Antonio worked on a fabric with the shape of fire. He used threads of different tonalities to contrast the figure and symbolize an ignited fire. To represent the element of earth, Antonio uses the root of a tree to illustrate its life growing from the ground. In his artwork, he intertwines threads of different colors, which, according to him, refer to Mother Earth.
