 Trials to find the right solvents were continued on a small portion of the Eleazar and Matthan lunette.Because of the height of the ceiling and the inaccessibility of the ceiling frescoes, the precise nature of the damage and the problems that would be encountered by the restoration team could not be entirely foreseen until after the decision to restore was taken, and the scaffolding was in place.According to Colalucci, the continued scientific analysis and the response of the restorers to the particular problems was an ongoing part of the process, rather than the conservation team deciding on a single treatment for every part of the building.
