Conservation team brings large map to larger audiences
By Edgar Walters
The Ransom Center’s archives are full of treasures waiting to be pulled off the shelves. But once paged from the stacks, some of those treasures prove difficult to handle.
Such was the case with Giovanni Battista Piranesi’s enormous 1786 print “Pianta delle Fabriche Esistenti Nella villa Adriana.” The 10-foot wide map of Hadrian’s villa is a popular item at the Ransom Center, but its impressive size complicates the process of sharing it with students and scholars. Now, thanks to treatment efforts undertaken by Ransom Center conservators, the map is far more accessible.
Previously, a complex set of folds allowed the print to fit, attached to a stiff paper stub, inside its book. The setup was not optimal: long-term folds left significant creases in the print, and the stub attachment was unwieldy and damaging.
The conservation team had a better idea. Conservators cut the map away from its stub and carefully unfolded the map onto a large work surface, where it was cleaned of superficial dust and grime. The creases were relaxed by a textile humidifier and then flattened under a weighted drying system. Conservators also mended small tears in the print using long-fibered Japanese paper and wheat starch paste.
Next, Heather Hamilton, Head of Paper Conservation, was tasked with creating a modified tube around which the print could be rolled. Her objective was to eliminate the need for folding, thus protecting the item from potentially harmful creases. Given the print’s large size, a standard tube would be too large to house on a shelf within the stacks. Hamilton’s answer was to roll the map onto a flattened, space-saving pad.
The pad consists of four layers. A corrugated board forms the core, which is then wrapped in thick foam. An outer layer of soft, thin Volara foam envelops the interior, which is cocooned by airplane cotton just below an exterior cloth surface. Hamilton used a giant needle to sew through the many layers, ensuring that everything was well-secured.
Finally, Preservation Housing Manager Apryl Voskamp created a custom archival box to house the print and its pad. The new lidded box has a layer of protective Volara foam and a drop front, which allows the print to slide out easily without risk of harm.
The map of Hadrian’s villa is frequently used by classes in the University’s School of Architecture, where students learn the importance of structure and accessibility. Applying those same concepts, Ransom Center conservators have brought new life to the map of Hadrian’s villa.
