At the beginning of the 1960s, Nivola began to use terracotta to create small-sized works, seen as a totally free form of expression, an alternative to the rigor required by public works, subject to the will of the clients and the need for architecture. The Beds, inspired by Etruscan sarcophagi, symbolize, by extension, the totality of man's existence: the life of a couple in all its variations, moments of solitude, happiness and despair. Nivola exhibits them on white bases covered with wheat sprouts, a symbol of rebirth traditionally used in Sardinia in the rites of Holy Week. From the microcosm of the Beds, we pass with the Beaches to the macrocosm of nature: Nivola with a few gestures outlines seascapes in which small figures rest on the beach or swim towards the horizon.
