The sculptures named Pinna Nobilis derive their name and their appearance from the shell of the homonymous bivalve mollusc, the largest in the Mediterranean waters. ​Made in bronze, the sculptures produced by Giorgio Andreotta Calò from 2014 onwards portray specimens of Pinna Nobilis in their life size. Next to the central body formed by the shell, the metal casting channels and the "embouchure" are integral parts of the sculpture, traces of the lost wax casting process and, at the same time, supporting elements of the work itself. Each Pinna has a naturally symmetrical shape: two lateral valves almost identical to each other make up the shell. In these works we find many aspects that cross the artistic research of Calò. The survey on the landscape and in particular on the lagoon of Venice, his native city, is common to several works created by the artist, who extracts some fragments and reworks them into objects with a strong symbolic and evocative charge. The specular shape of Pinna Nobilis also recalls the theme of the double, its symbolism and its being an investigative tool of our present, suspended between reality and its virtual representation.
