(syllabus)
First module, 150 hours:
The training of the first module will be carried out at the University Conservation Laboratory, on a bi-chrome, black and white, opus tessellatum with geometric and floral decoration. The mosaic come from the archaeological excavation of Well Q15, executed to instal Metro C in Rome . The mosaic, detached from its original place, is glued on canvas and is divided into 14 sections and fragments.
The module will address the following topics, referring to the mosaic at the Laboratory, with possible comparisons with other work cases:
- Study of original materials and decorative motifs.
- Study of conditions and causes of degradation.
- Study of ancient and modern conservation / maintenance interventions and discussion on whether or not to remove them.
- Methodologies of intervention, pros and cons of different methods identified.
- Implementation of all conservation operations needed to prepare the artifact for assembly on a new support: cleaning of tessellatum backside, tracing 1:1 the decorative pattern from the back, temporary re-bedding on clay of the mosaic main part, removal of the facing used for detachment, removal of old mortar repairs, tessellatum reintegration, new facing with cotton gauze, cutting into sections, removal of clay from the back and storage.
- Graphic and photographic documentation of the data acquired with observation during the study phase and documentation of carried out intervention operations.
- Planning the restoration of a mosaic.
The module provides lectures on mosaic in general (materials, technique and typologies) and on mosaics detached from their original place (detachment methods, different supports, conservation problems and different intervention methods both on site and laboratory).
Second module 150 hours
During the second module, conservation intervention on Well Q15 mosaic is continued, facing topics such as:
- Different support methodologies for detached mosaics.
- Lime mortars for tessellatum re-bedding.
- Stone tesserae surface cleaning methods.
- Lacunae reintegration.
- Implementation of all conservation operations needed to prepare the artifact for public display: preparation of the support that will house the mosaic sections, positioning of the sections on the new support with layers of mortar, tessellatum surface cleaning, tessellatum lacunae re-integration or treatment and presentation of the mosaic.
- Graphic and photographic documentation of carried out interventions.
Third module 150 hours
Module 3 will be carried out at the archaeological site of Carsulae, addressing all operations needed for in situ mosaic stabilization, operating on one or more mosaics that will be assigned to the course:
- Surface cleaning and vegetation removal.
- Mobile tesserae re-bedding in their original position with lime mortar.
- Grouting of detachments between tessellatum and preparatory mortar layers, with infiltration of hydraulic liquid mortars.
- Mortar edging for tessellatum protection and containement
- Lacunae and interstices between tesserae in-filling with lime-based mortars.
The module will also include lectures on mosaics deterioration in archaeological sites, deterioration stabilization methods and protection and prevention methods used on the site, such as water drainage and backfilling.
(reference books)
No text on mosaic restoration is adopted as course text. For various topics dealing with different aspects of mosaic conservation, both for ancient and modern mosaics and floor and wall mosaics, it is referred to the following bibliography.
