RESTORATION DIARY TYPES OF ALTERATIONS

Pattern of lines (or "tratteggio")

Technique used to deal with lacunas which disturb the overall view of the fresco. It is always done in water-colours so that it can be reversed (undone) at any time. However, for this project, we chose to continue using the 19th century technique of reconstructing the continuity of the imitation architecture (incomplete or broken architecture is not "believable") while - obviously - making use of a more suitable method in order to solve two conflicting problems: reconstructing the scene in its entirety but using a technique (known as "tratteggio") which ensures that the restored area is immediately recognisable (why would anyone ever paint a wall - in water-colour at that - with fine vertical lines - coloured, straight, and parallel - which in no way follow the layout of the original painting?)

First, the area is marked out and the sketch is prepared; then, parallel vertical lines are drawn close together, forming a pattern that in no way corresponds to the original painting. Centre: one of the phases of the operation.
