26 The history of the Vienna Genesis and former interventions since 1664
the miniatures50. Wächter learned about the use of parchment glue during internships in
Italy at the institute “Istituto Centrale Patologia del Libro”, today ICRPAL, and at the con-
servation department of the Vatican library. In an article on the conservation of the Vienna
Dioscorides Wächter admits that the addition of 1 % vinegar to the parchment glue is con-
troversial. The solution becomes less viscous with the addition of vinegar. The leaves of the
Vienna Dioscorides were moistened with ethanol, then rectified by stretching and spraying
with parchment glue. Tears were closed with gold beater’s skin51. When Hilde Kuhn treated
the folios of the Vienna Genesis, she probably also sprayed them with parchment glue con-
taining vinegar to flatten the parchment and to stretch deformations. She might have dried
the parchment under weights instead of stretching it on a frame. Pressed folds can be ob-
served on some folios. Gold beater’s skin was used much less frequently, if at all, than on
the leaves of the Vienna Dioscorides. Many folios show mending of tears with paper fibres
(Fig. 10). The method of mounting degraded folios of parchment between polyacrylate was
also used for the parts of Tabula Peutingeriana (Codex 324) and the folios of the so-called
black prayer book (Horarium Galeazii Mariae Sfortiae V. ducis Mediolanensis, Codex 1856).
