The goal here is to show all the various handling of Sinaiticus through the centuries involving quire numbers, Arabic numbers, corrections, bindings, mini-ink, super-ink, Eusebian apparatus, and other elements under the modern theory.
In this context of massive handling over centuries (theorized) we can counterpoint the pristine CFA and the amazing preservation of the New Testament.
As we come across these, from now on, we will place them in here, the most important resources will likely be:
Skeat and Milne (1938)
CSP site, including various papers (2009)
New Perspectives On the Ancient Biblical Manuscript (2015)
The green corrector information is taken from the summary given by Robert Waltz
5th or 7th centuries - C correctors - Skeat p. 65
638 AD - "plausible guess" brought from Caesarea to Sinai - Lake, 1922 https://books.google.com/books?id=IL7fAAAAMAAJ&pg=PA2
600-700 AD - 2 Esther and Ezra notes have wording not consistent with 4th century
unknown - 1st retouching
8th century - 2nd retouching
8th century - 2nd quire numeration (Skeat)
"The first folios of both of the Hermas quires contain two sets of numbering in the upper margin: in the top right there is the usual eighth-century writing and ornaments, and in the top-left the less visible old numbering." - Dan Batovici
scribe of the eighth or ninth century has retouched with fresh ink many pages of the Sinaitic MS
Medieval correctors - D and E - Skeat p. 65
D is known for accents.
"medieval corrections.. There are three corrections in the NT: at Matt 19:3; 1Tim 3:16; and Acts 3:13 (and there is one in Proverbs). There are a few pious notes, and some Arabic glosses, notably one that may be dated between 1453 and 1492. " - David Parker - https://books.google.com/books?id=guYq9rohFQ8C&pg=PA45
"We may ignore
Dionysius - Milne and Skeat hedged their bets by writing that 'the latest desultory scribblings to which any approximate date can be assigned seem to belong to the twelfth century'. - Parker p. 117
1200 - Theophylact note' A date around 1200 seems a safe proposal. - Parker, p. 117
1453-1492 - Arabic note on Revelation 7:4 - Parker p. 119
1800s - Arabic is very recent (Tregelles)
1844 - rebinding
=============================Both the form of the letters, which appear to be no later than the text, and their regular placing against the left bounding line of the first column of writing2 (see Fig. 3) strongly suggest that this numeration is contemporary, although the writer cannot be identified with any of the scribes of the text. This is also the opinion of Lake (N.T., p. xvi; O.T., p. xix). In the New Testament these quire-numbers are all one in advance of what would be expected from the numeration of the Old Testament, whereas the later numeration, in the right-hand top corner, which is ascribed to the eighth century, runs on continuously throughout the Bible. - Skeat and Milne p. 7
In review, we may also touch on puzzling anomalies, like the Revelation of Sinaiticus being seen as a pre-Andreas commentary, the x-ray vision of Tischendorf on John 21 and the Mark ending cancel sheet. And the linguistic perspective of James Donaldson.
Some notations are made of events without much indication of the theorized dates:
More discussion here:The retracing of the characters (main text, corrections, some quire numbers and some of the squiggles) was repeated several times throughout the history of the Codex Sinaiticus, always using different types of inks.
The ink used for the second retracing of the main text, for example, appears to be more friable than the one used to write the original text, suffering from major ink loss.
... There have been two, possibly three, re-tracings of the brown ink text
