niques with visual analysis, we believe that all the folios of the Vienna Genesis are made
from sheep parchment. The sheep parchment was treated with glue made from offcuts of
parchment. The thickness of the layers of parchment glue probably differ from folio to
folio.
Comparison of the parchment of the Vienna Genesis with the Codex Rossanensis,
the Codex Sinopensis and the Vienna Dioscorides
The Codex Purpureus Rossanensis46, a 6th century illuminated Greek Gospel book writ-
ten in silver and gold ink on purple parchment, is considered to be closely related to the
Vienna Genesis. A single bound volume of 188 folios survives from the original manu-
script that was in two large volumes; only the Gospel of Mark is complete. The manu-
script is kept in the Museo dell’ Arcivescovado in Rossano Calabro, Italy. Exposure of the
codex to high humidity led to biological damage during the first half of the 20th century47.
Subsequently, gelatine and cellulose nitrate were applied to the surface of the degraded
parchment and the miniatures on the first 20 pages. The last 15 pages, which exhibit severe
insect damage and corrosion of the silver ink, were reinforced with silk gauze and gelatine
on both sides48. While the quires at the front and back of the manuscript were heavily
restored, the remaining folios survive in relatively untouched condition. The Codex Ros-
sanensis was recently analysed and conserved at the Central Institute for Restoration and
Conservation of Archival and Library Heritage (ICRCPAL) in Rome. During the conserv-
ation treatment, Vnouček had the rare opportunity to examine the parchment text block
at ICRCPAL in February of 201449. The folios of the Gospels are similar in size to those of
the Vienna Genesis, with average dimensions of 307 mm x 260 mm50. Surprisingly, almost
all of them have survived intact as conjoint bifolios. The thickness of the parchment ranges
from 0.05–0.19 mm, which is very close to the parchment thickness of the Vienna Gen-
esis51. Over the surface of the folios the purple colour and its hue are more variable than
in the Vienna Genesis. This might simply be due to the fact that a larger number of folios
are preserved in the Gospels and that this variation in colour is normal for a purple manu-
