Seite - 255 - in The Vienna Genesis - Material analysis and conservation of a Late Antique illuminated manuscript on purple parchment

Sophie Rabitsch, Christa Hofmann, Junko Sonderegger 255 lysed by X-ray fluorescence (XRF), see chapter on inks. Results show that while some of these stains are of unknown origin, some are definitely silver ink. Orange or brown stains on the edges or in the text area are frequently occurring (Fig. 12), which could not be iden- tified. On the folios 20, 21, and 22 large, matching rust-like stains can be found (Fig. 13), but their origin could not be confirmed by XRF. Many folios show glossy brownish stains that seem to have been caused by adhesive residues along the edges and in the text area (Fig. 14). These stains might originate from former repairs or conservation treatments. All folios show brownish or slightly glossy traces of adhesive and discolouration on the inner margins (Fig. 15), which probably stem from former bindings. There were at least three of them: the original binding, the binding with the Latin codex in which the Vienna Genesis was discovered in Vienna, and the pamphlet binding made by Peter Lambeck in 1664. Another phenomenon are wax-like stains (Fig. 16) of indeterminable origin. They could not be identified with XRF nor UV-visible diffuse reflectance spectrophotometry with optical fibres (FORS5). Some round waxy stains could originate from the use of candles. Whitish stains that appear in the text area and in the miniatures might have been caused by former treatments with adhesives, for example on the folios 5, page 9, 6, page 11, 9, page 17, 12, page 23, and 17, page 34 (Fig. 17). We assume that numerous efforts were made in 5 Carried out by Aceto et al., 2017. Fig. 11: Tide lines on folio 5. Fig. 12: Orange stains on folio 12, page 24.
