Il Salterio di San Romualdo (secolo IX), primi interventi di restauro e indagini conoscitive
The San Romualdo Psalter is a manuscript dating back to the 9th century, which for a long time has been thought to have been written by the saint himself. Its rubrication turned white making it completely unreadable, the previous repairs led to distortions of the parchment. The codex was dismantled and reproduced using UV fluorescence, with a remarkable improvement in the text’s readability. Previous repairs have been removed using rigid aqueous gels; distortions have been treated with humidification and tensioning with neodymium magnets. The manuscript has been resewn using a Japanese paper concertina and double thread technique, and bound on beech boards and full alum tawed goatskin.
