The textured aspect of a painted wall: hypothesis of staining through the combination of traditional and digital techniques

Abstract

This study on architectural representation focuses on
the Quadratura genre, an illusory type of architectural
painting that uses the perspective technique to create
the illusion of a three-dimensional space on a plane or
vaulted surface. I have selected as main object of my
work a frescoed perspective scene found in the city of
Bologna, painted by Antonio Galli Bibiena. This fresco
represent an architectural scene, placed at the end of
a promenade running through the building, mimicking
the wings of a theatre stage. This is a hidden cultural
heritage, unknown to most people, unfortunately exposed
to the elements, which caused heavy damage on
the painted wall, though leaving some visible signs.
This study attempts a reconstruction of the scene, and
of its original staining, on the basis of a previous accurate
analysis and on a combination of different architectural
survey techniques.
