Active in Rome in the second quarter of the 20th century, Volterrani studied at the Rome Academy of Fine Arts in the 1910s. His style was influenced by the taste for Roman statuary of the artists gravitating around the magazine Valori Plastici in the years after World War I. Having taken part in the first Rome Biennale in 1921, he began to be recognised in the 1930s, collaborating on the building of the organ for the main hall of the Pontifical Institute of Religious Music in 1933 and presenting work at the World’s Fair in New York in 1938. The works produced after World War II include a monument to the fallen in Anagni, a wax statue of Saint Maria Goretti for the hospital in Nettuno (1947) and the baptistery of the church of San Leone in Rome (1952). He took part in the 7th Rome Quadrenniale in 1955.
