28 The history of the Vienna Genesis and former interventions since 1664 Piece of paper or parchment On folio 11, page 20, a large tear is bridged at the lower margin with a broad and relatively thick piece of paper or parchment. The adhesive is yellowed. The repair was coloured and now appears brown (Fig. 11). This crude repair can already be seen in the first facsimile from 1895. Adhesive residues on inks and paint layers Shiny areas on the folios, glue residues and brushstrokes can be observed on text areas and on the miniatures. They probably originate from efforts to consolidate ink and paint layers. Adhesive residues are visible on some miniatures, e. g. on folio 20 (Fig. 12). Under UV light, additional brushstrokes and a blueish haze on the paint layer can be detected on several paintings, e. g. on folios 20, 22 and 23. The brushstrokes that are visible in normal light can already be seen in the reproductions of the first facsimile. The bad condition of the miniatures as observed by Waagen in 1839 might have led to various consolidation efforts in the 19th century. Fig. 12: Adhesive residues on folio 20, page 40.
