Like the previous artist, Simo Capecchi, Gérard is also working as an architect. Moreover he has been teaching drawing and perspective to other architects over 30 years.
"I'm mad about perspective and I have made many spherical and cylindrical drawings. Together with Simo, we decided to sketch Naples from the site of the Certosa di San Martino. It's a hill, with a very beautiful view on the old city. What a fine subject to begin a panoramic view! I decided to zoom in on the centro storico, to show the incredible density of the buildings."
