I Mani is a work made of light and shadow, of matter and emptiness. The spectator is invited to interact with the work and become part of it: the moment his hand holds a small bronze sculpture depicting a bunch of grapes, the shadow of the sculpture itself projected onto the wall is completed assuming the appearance of a human profile. The shadow and the expression of the profile will change according to the shape of the touching hand. Each hand is unique, shaped by the genes of our ancestors, the Mani. Squeezing a bunch of grapes, touching a sculpture, playing with the shadow are primordial and ancient actions that can bring back to a truer dimension of contact with the physical and ancestral material of nature.
