Contenitore (con pietra levigata), 1987

Cavenago relates a round stone, taken from the bed of a river, and an irregular parallelepiped made of galvanised sheet metal. The `geometric` solid, symbol of artifice, stands out vertically and rests its angled end directly on the plant, the balance is supported only by the round stone which, by virtue of its sphericity, seems to give the object a possibility of escape rather than stability.

It will be the reflection on this opportunity that will mark an important part of the first phase of his research: to give the static nature of the 'statue' a possibility of movement. An intuition that so far has nothing to do with kineticism and that more simply questions the possibilities of an archetype of material culture: the wheel. He transforms it from a motor prosthesis into an instrument for modifying the perception of three-dimensional art, creating a consolidated but 'transportable' space, a feature that undermines that cornerstone of artistic praxis that wants the observer in contemplation of the motionless work.

Luigi Di Corato, 2003

Created in the same year and in the same place as Contenitore (con pietra squadrata), this second work is not a duplicate but its necessary reversal, the missing half of a line of reasoning which, to be complete, had to be carried through to its conclusion on both sides of the nature/artifice dichotomy. Whilst in Contenitore with the square-cut stone the dialogue was between two regular geometric forms—the sheet-metal parallelepiped and the carved travertine cube, both with right angles and both structurally stable— here Cavenago replaces the squared block with a smooth pebble, taken from a riverbed: a stone whose shape derives not from any human intervention, but from the extremely slow work of the water, which has eroded and rounded every edge over the course of geological time.

The change is not merely material; it is structural. The vertical geometric form in galvanised sheet metal rests with its angled end directly on the rounded stone, and the entire balance of the work depends on that single spherical point of contact. It is a condition of stability radically different from that of its twin container: there, the travertine cube provided a firm base, a secure supporting surface; here, the round shape of the pebble, by its very nature, offers no definitive anchorage; if anything, it seems to offer a possibility of escape rather than support, a balance always on the verge of breaking in the direction in which the sphere might roll.

It is in this seemingly minor detail that one of the most fruitful core ideas of the artist’s entire future work lies. As Luigi Di Corato has observed, it is precisely this reflection on this possibility—the static nature of the ‘statue’ which glimpses within itself a margin for movement—that marks a crucial part of the early phase of Cavenago’s artistic journey: not yet a kinetic aesthetic in the strict sense, but an exploration of the potential of an elementary archetype of material culture – the wheel – present here only by allusion in the spherical form of the stone. From a motorised prosthesis, the wheel is here imagined for the first time as an instrument capable of altering the very perception of three-dimensional sculpture: no longer a stationary object before which the observer pauses in contemplation, but a consolidated yet potentially transportable space, which undermines at its very root one of the most solid assumptions of the sculptural tradition: the immobility of the work as a condition of its appreciation.

Viewed as a pair, the two Contenitori from 1987 thus form a small theoretical diptych: on the one hand, complete stability, guaranteed by the union of two regular geometries; on the other, an unstable equilibrium, dependent on the point of contact between an industrial surface and a natural form which already alludes, in its very simplicity as a circle, to everything that is to come: vehicles, sculptures on wheels, the entire catalogue of mobile objects that would soon become Umberto Cavenago’s most recognisable hallmark.
