- Dates: In the lead, you talk about how the codex was first thought to have been written in the 8th century but is really from the 6th century. I don't see anything elaborating on this in the body of the article though - per WP:LEAD, everything in the lead should be in the body as well. You might be able to cite the Parker and Birdsall or Hatch articles listed in the further reading for this.
- Infobox: The note in the infobox says "Close to Codex B." Does this mean physically close or similar in content?
- Lead: It is often used in critical editions of the Greek New Testament. Why is this? What makes this manuscript more suitable than others?
- Chapter divisions: The codex uses a peculiar system of chapter divisions. What is this peculiar system? What is so peculiar about it?
- Script: The commentary was written in a different kind of uncial script. Different from what?
- Variations and omissions: The style here is inconsistent; the first entry has the scripture reference followed by a dash, the next two have the scripture reference followed by "it".
- Other codices: as in codices Sinaiticus B C Θ L 33 700 892 1241 syr, and copbo. Would it make sense to put commas in between the entries here?
- Luke 9:10: What is the standard text of this verse?
- Independent readings: There are 3 independent or distinctive readings. Are these readings the same as the variants listed above? If not, what are they?
- Category: Alands considered the quality of the text to suit his Category III. Can you briefly explain what Category III is?
- Prose: one folio was supplied with paper (folio LXVIII). What does this mean?
- Corrections: edited the list of corrections in 1957. What is this list of corrections?
- Reexamination: The codex probably needs another examination with modern technology. It is problematic to make this kind of statement in Wikipedia's voice without backing it up; either add "according to so-and-so" or explain why the codex needs to be reexamined.
- Lower text: I don't know anything about palimpsests, so I am unclear on how Tregelles was able to read the lower text if it had been scraped off. Did he use some kind of chemical process? The image provided, File:Zacynthios_facsimile.JPG, seems to show only one layer of text, so I am somewhat confused.
- Significance: I am left wondering what makes this manuscript special. Is it just another manuscript, or is there something distinctive about it which makes it especially important? It would be great if you could include a "significance" section explain why this manuscript matters.
Thank you for your work on this article, I enjoyed reading it! I've made a few changes to the prose, trying to improve readability, so please look over my edits and make sure I have not introduced any errors. Overall, you've done a good job on the article, but it seems a little superficial - it leaves me with lots of questions. Since the article is pretty short right now, I think you have room to expand it to explain some of the technical content and add more detail. For example, you write, the early history of the manuscript is unknown, but hasn't there been at least some scholarly speculation on its early history which could be included? Something like the "Provenance" section in Codex Vaticanus would be great here. I'm placing the article on hold for now - just address the above comments and I'll be happy to pass it. Keep up the good work! --Cerebellum (talk) 18:34, 22 April 2012 (UTC)
