The traces of the historic construction yard: a difficult identification and an arduous conservation
What are the traces and stratigraphic signs that can provide us useful elements for the reconstruction of the historic building yard? How can we deduce the construction temporal sequence from these signs? Often these traces are fleeting, leading to serious archaeologic information losses. So, what precautions need to taken? Four example cases are investigated, very different each other: 1) S. Maria delle Grazie church: building archaeological analysis reconstructed the sequence of “under wall” constructions (17th c.), including sophisticated static modeling; 2) S. Maria in Passione archivolt: the medieval stone structure keeps track of the construction work sequence and timing; revealed by a precision stratigraphic observation; 3) Borzone Abbey complex: sophisticated laboratory analyses allowed to identify the first phase of construction (12th c.), settling some issues that had been debating for some time; 4) Grimaldi’s paintings, OPP-Cogoleto (20th c.): the painter wrote on his picture “painted in sixty days”; analyses were preformed to evaluate the truthfulness of this statement; here, more points of view are also involved in reading the whole (mental illness, influence on the way of painting, the use of always the same material...). The reconstruction of a construction yard that last for only thirty days can be very interesting, difficult to decipher, complicated to preserve.
