Between 1985 and 1987, in Tuoro sul Trasimeno, a project conceived by the artists Pietro Cascella, Mauro Berrettini and Cordelia Von Steinen took shape with the critical coordination of Enrico Crispolti: 28 artists from different backgrounds and research directions intervened in the locality of Navaccia, near the lake, meditating on a single theme, the column, and using a single material, the “pietra serena”. The columns are arranged in a caudate spiral, and make the site a modern Stonehenge. Staccioli thinks of a form that, as it is already evident from the hypothesis proposed in the maquette, respecting the column theme, seems to have fallen there from above, a sort of wedge driven into the ground in precarious equilibrium.

In fact, if the column is an element born to support a weight, at Campo del Sole this task is not performed; the sculptor thus plays on this ambiguity to construct an autonomous form, a sculpture, aimed at soliciting questions and activating the sensitivity necessary to elaborate answers.
