In my first post about making a model of P46 (TM 61855), the papyrus codex of Paul’s letters in Greek that is split between the Chester Beatty Library in Dublin and the University of Michigan, I discussed the different sizes of the bifolia. Now I want to turn to the elements that usually protect the central folds of papyrus codices, the stays on the inside of the quire. In the case of P46, these items do not survive (if they ever existed at all).
The single-quire papyrus codex is a relatively straightforward construction. A stack of papyrus sheets folded in half and bound. The binding can either be directly through the central fold or “stabbed” through the codex from front to back.
For larger (that is to say, thicker) single-quire codices, it seems as though binding through the central fold would be the more practical option. From ancient examples that have survived in a relatively good state of preservation, like several of the Nag Hammadi codices, we have learned to expect leather or parchment stays at the center of the quire in order to protect the papyrus from being torn by the pressure of the binding agent, whether it is thread or a leather tacket.
In the image below of Nag Hammadi Codex VI (TM 107746), which was bound with two leather tackets through two leather stays, the lower stay is visible, still in place:
(Side note: Does anyone know if there are other images showing the Nag Hammadi books with the stays in place before they were disassembled?)
Stays have survived in several of the Nag Hammadi codices. When the papyrus leaves of the Nag Hammadi books were removed and mounted, the stays were stored together with the covers. The cover and stays of Codex VI are now in the Bibliotheca Alexandria:
In other surviving single-quire codices, the stays have survived only occasionally. But when such stays are absent, there is often evidence that they were once present in the form of stains or discoloration on the central bifolium in exactly the place(s) where we might expect stays. We see this in the Bodmer Menander codex (TM 61594):
A similar discoloration (lightening) can be seen in the central bifolium of the Crosby-Schøyen codex (Schøyen MS 193, TM 107771). With the Berlin Proverbs codex (Staatsbibliothek zu Berlin, Ms. or. oct. 987, TM 107968), which has been rebound in a modern binding, we have a glass frame that preserves a parchment strip that was almost certainly the stay from the center of the quire:
This all makes sense. When papyrus is folded, it weakens. When it is punctured for binding, some reinforcement would seem necessary around the points of friction between the papyrus and the binding agent. I have learned from unpleasant experience that binding threads or leather tackets will rip right through a whole stack of papyrus sheets if they are unprotected. So, it’s quite curious to me that there does not seem to be evidence for any protective stays at the center of the single quire that makes up P46.
If we digitally reunite the now separated halves of the bifolium at the center of the quire, we see no evidence of stays (the color mismatch between the two folia here seems to be due to different conditions during photography):
There is evidence of two pairs of binding holes through the central fold of the codex, but there is no evidence (at least as far as I am aware) for the presence of stays. I’m genuinely puzzled as to how the binding would have worked without stays. For my model, I used linen thread and included a pair of parchment stays just to make the codex stable and usable:
If I were to do it again, I would probably use leather stays, as the parchment stays have already begun to tear slightly under the pressure of the binding threads.
In the next post, I’ll talk about some other aspects of the model.
