Seite - 27 - in The Vienna Genesis - Material analysis and conservation of a Late Antique illuminated manuscript on purple parchment

Christa Hofmann, Sophie Rabitsch 27 Traces of former conservation treatments and mountings When studying the condition of the Vienna Genesis, the folios were compared with the images in the three facsimile editions and the photographic images (colour transparencies) from the last edition. It has to be considered that the facsimiles have been retouched and do not show the folios in their exact contemporary state. The found traces were summar- ized in the following groups: Parchment patch On folio 2, an overpainted patch of parchment was used to cover a round hole, see figure 11 in the chapter on parchment. Because of technological aspects, it can be assumed that this repair does not originate from the manufacturing process. The patch is a bit thicker than the rest of the folio and does not cover the hole completely, which might indicate that it was added later. A repair carried out by the parchment maker would have been thinner and more delicate, see chapter on parchment. According to visual observation and analysis of the paint by XRF and FORS, no differences in the paint layers on the patch and the surrounding area can be observed. The painter could have applied the patch while working on the miniature.. Fig. 11: Repair with piece of paper or parchment of folio 11, page 20 Open-Access-Publikation im Sinne der CC-Lizenz BY 4.0
