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. Nivola with a few gestures outlines seascapes in which small figures rest on the beach or swim towards the horizon. In the seventies Nivola, disillusioned and disgusted by contemporary society, creates new beds and beaches, humorous and sarcastic, often with an open sexual content, and creates the series of the Piscine, places of urban leisure where bodies are massed and every relationship with the nature is denied or distorted.
