There is a strong architectural element in Pomodoros work. He created a number of pillar or towerlike sculptures which he described as encapsulating a minimum emptiness that encircles the mass and gives force to the upward movement of the work. Like the other works in Jeddah by Pomodoro, Circular Mass was purchased from the Marlborough Gallery in Rome through the auspices of the architect Julio Lafuente.
Arnaldo Pomodoro was born in Morciano di Romagna, Italy in 1926 and now lives and works in Milan. From the mid 1940s until 1957 Arnaldo Pomodoro served as a consultant for the restoration of public buildings in Pesaro, advising on the restoration of buildings after World War II, while also studying stage design and working as a goldsmith with his brother Giò Pomodoro. In 1960 he met David Smith and Louise Nevelson during his first trip to the USA, and in 1961 he joined the group Continuità.
His brother is Giò Pomodoro who also has sculptures in Jeddah.
