Giovanni Broggi (1853-1919) worked in Milan and exhibited at the Promotrice in Turin from 1884. He is noted for his romantic works, and it is interesting that he has here translated one of the most celebrated 'romantic' images of art history from the two-dimensional to the three-dimensional. Broggi has ingeniously attempted to imitate the celebrated sfumato and palette by using a semi-translucent and coloured stone such as alabaster.
