Seite - 32 - in The Vienna Genesis - Material analysis and conservation of a Late Antique illuminated manuscript on purple parchment

32 The history of the Vienna Genesis and former interventions since 1664 damage to text and miniatures might have occured. The documented treatments were undertaken before facsimiles were produced in 1895, before 1931 and in 1975. Since 1895, the folios have been stored between glass or polyacrylate plates. During the treatments, the parchment was more or less flattened. Tears were mended with strips of paper and silk gauze, thinned paper, paper fibres and pressure sensitive tape. The miniatures were probably consolidated on several occasions, at last with parchment glue in 1975. Losses in the parchment were not infilled. Text, parchment and miniatures were not retouched. The curator Eduard Chmelarz, the bookbinder Alois Liška and the conservator Hilde Kuhn worked with the materials and the knowledge available at their respective time. Their treatments show respect for the original and a considered approach. Despite an eventful history marked by wars, the remaining folios of the Vienna Genesis are surprisingly well preserved. It is the aim of this project to continue with respectful treatment, safe storage conditions and responsible preservation of this unique artefact. Literature Aceto, M., A. Agostino, G. Fenoglio, P.
