tique style, by peeling away fine layers of tissue from the hair side of the skin, the presence
of hair in many follicles indicates that the epidermis was not entirely removed from the
surface. A very thin, oval-shaped area on folio 6v (the hair side) resembles the type of rup-
ture that can develop in sheepskin while it is being dried under tension on the frame64. It
is unclear, however, whether this is a naturally occurring area of delamination or evidence
of the work of the parchmenter to produce such a thin product. When compared to the
small size of the Vienna Genesis (originally only 96 folios), it may have been difficult for
the craftsmen that produced the Codex Rossanensis and the Codex Sinopensis to obtain
the required number of skins of sufficiently high quality for these large books of 400–500
folios each, and to prepare all of the parchment to the same standard.
The parchment of the 6th century Vienna Dioscorides (Austrian National Library,
Codex Medicus graecus 1) offers another interesting comparison with the Vienna Genesis.
This compendium of six pharmacological and zoological works was produced in Constan-
tinople around 512 for Princess Juliana Anikia65. 485 folios are preserved with 496 images
of plants and animals. One quire consists of four bifolios that are organized in standard
Late Antique order according to Gregory’s rule starting with the flesh side outermost. The
dimensions of the folios vary a lot throughout the text block, going from about 370 to
391 mm in lenght and from 300 to 320 mm in width. The folios have uneven edges due to
trimming. The Vienna Dioscorides was conserved by Otto Wächter in 196066, see chapter
on history. The treatment included the application of parchment glue, the stretching and
drying of folios and mending with gold beater’s skin. In 1985 the manuscript was newly
bound into three volumes. The parchment of the Vienna Dioscorides was produced in the
Late Antique style. According to visual (Vnouček) and biomolecular analysis by eZooMS
(Fiddyment), the parchment was made from sheep skin. On seven folios, the thickness
was measured and ranged from 0.104 to 0.181 mm67. The position of the flanks of the
animals varies a lot, as large areas of bellies are included. These areas can be found either at
the front margin, indicating a vertical position of the spine of the animal, or at the lower
margins indicating a horizontal position of the animal spine. Quite unusually, flanks of the
animals can be found at the top margins of some folios. This means that the skins of larger
and smaller animals of different ages were combined in no special order. The outer dimen-
sions of the folios and their edges are very uneven. The size of the manuscript was probably
altered during repair and rebinding campaigns. The quality of the parchment throughout

67 Given the presence of the glue on both sides of the folios these measurements are not those of the
original parchment.
