38 The parchment of the Vienna Genesis: characteristics and manufacture
2. They were made at first of a muddy (yolk) colour, that is, yellowish, but afterwards white
parchment was invented at Rome. This appeared to be unsuitable, because it soils easily
and harms the readers’ eyesight – as the more experienced of architects would not think of
putting gilt ceiling panels in libraries, or any paving stones other than ones of Carystean
marble, because the glitter of gold wearies the eyes, and the green of the Carystean marble
refreshes them.
Isidore’s interesting description of the colours of parchment continues in the fourth and
fifth paragraphs:
4. Parchment comes in white or yellowish or purple. The white exists naturally. Yellowish
parchment is of two colours, because one side of it is dyed, that is yellowed, by the manu-
facturer10.
5. But purple parchment is stained with purple dye; on which is melted gold and silver so
that the letters stand out.11
The description of the yellowish colour of parchment that was first produced in Asia
Minor is correct, as sheep parchment typically has a yellowish hair side and a white
flesh side. However, complaints about the whiteness of parchment that was developed in
Rome harming the eyesight raise an interesting hypothesis. It is possible that the author
is referring to parchment with equally white hair and flesh sides. The only method of
making the two sides of sheep parchment equal in appearance seems to be by peeling off
the epidermis layer on the hair side. The resulting material is not only a luminous white
colour but also very thin, and these are the two principal characteristics of Late Antique
parchment.
The use of purple-coloured parchment in early manuscripts is mentioned in several
ancient accounts12. The colour purple, especially when used for whole pages in a book,
was a symbol of great wealth, high social status and prestige13. Manuscripts written in gold
ink on purple parchment had a promotional value symbolizing imperial culture14. Saint
10 It is hard to imagine that only one side of the parchment would be coloured with a yellow dye so
this description is more likely of the type of sheep parchment that existed earlier, with a yellow hair
side and a white flesh side.
11 This is a clear Late Antique reference to purple codices such as the Vienna Genesis.
