Visit to Co. New Tech. Restoration Site in Aquileia

Aquileia, today a small town, but one of the most important archaeological Roman sites in Northern Italy, was founded as a colony by the Romans 180/181 BC, not far from the lagoons.

One of its most beautiful monuments is the Cathedral (figures 1, 2) built by Patriarch Poppo in 1031 and rebuilt about 1379 in the Gothic style by Patriarch Marquard of Randeck. The interior has a nave and two aisles, with a noteworthy mosaic pavement from the 4th century (figure 3).

The town hosts the National Archaeological Museum (figures 4,5,6,7) that contains over 2,000 inscriptions, statues, mosaics and other antiquities found during archaeologic digs in the area.

Co. New Tech. is now restoring some ancient Roman statues and artifacts within the Museum.

The Smart Cities research team (figure 8) had the opportunity to visit and see the restoration work on January 29th 2018 under the guidance of Co. New Tech. Architect Fabrizio Benvenuti.

Statues & Artefacts Under Restoration

Figure 9: Statue of Claudius
Marble, First Century AD

Figure 10: Statue of Woman - Venus
Marble, Bronze First Century AD

Figure 11: Man’s Head
Marble, First Century BC

Figure 12: Statue of Augustus
Marble, First Century AD

The Restoration Activities Consist in:

·        X-ray examinations of the artifacts to check if the inner metal support items are still in good condition. For example, the bronze leg of the Statue of Woman - Venus (figures 13, 14).

·        Documentation phase: 3D photographic survey (figures 15, 16). This operation is important to map and consequently study in detail the condition of the artifact under the scanning electron microscope from 20x up to 50x magnification. In this way, any surface micro-damages, cracks, or plaster integrations become totally visible.
For example, on the statue of the ship’s captain ("Navarca") traces of dye have been found, as in use at the time. These traces must be preserved as evidence of the past. The results of this investigation will be an important document for posterity.

·        Cleaning (figure 17): first of all, it is important to detect any situation of degradation for example due to surface disintegration.
This happens when artifacts are recovered from underground: clay/soil inclusions, or scratches due to digging operations may be found.

Cleaning procedures are performed through different methods according to the type of problem:

- scalpel: to remove soil/clay inclusions or recent cement mortars
- vapor: to dissolve fatty substances of recent interventions
- ion exchange resin: to eliminate the problems of surface sulfation

We would like to thank Dr. Marta Novello, Director of the National Archaelogical Museum of Aquileia, for her kind hospitality.
