Beginning in 1966, he signaled the cultural centrality of the tool pointing toward, among other reasons, the “coincidence between art and work.” In 1976 he created the installation Algunos Oficios (Some trades), an homage to the five traditional trades of blacksmith, carpenter, bricklayer, stonecutter, and horticulturist. This relationship between art and craft has been present throughout the course of his professional trajectory.

Mesa de Albañil is an example of this. The work shows a table on which the action of a worker appears to momentarily rest -casting, stonecutter’s knife, lead line. The table, as the place of synthesis both of the work and of human life, is another constant in his work. On his table is found written the following phrase: “Ellos cantan haciendo la casa de los otros” (They sing making others’ homes) (Praise for Italian stonecutters. Gustavo Riccio). The work is completed by a glass dome similar to those found in exhibition halls or natural science museums.
