With this relief, Bernero won the second prize of the first sculpture class of the competition Clementino banned in 1766 and that same year, he won first prize at the School of Nude. He stayed in Rome until 1769 by attending artists and scholars of the Cardinal Alessandro Albani circle and continuing his preparation at Ignazio Collino. In 1770 he returned to native Piedmont where he obtained official duties at the Savoy court and the Royal Academy of Turin.
