- Cambridge University Library, Additional MS 2610
What archaeologists can actually examine
A Greek parchment Gospel codex written in majuscule script, with substantial portions of all four Gospels. The surviving book is incomplete and includes chapter apparatus, punctuation, corrections, and lectionary markings that expose how it functioned after copying.
A separately identifiable artifact
The stable identity rests on GA 013 and Cambridge University Library, Additional MS 2610, not on a generic manuscript title.
Material evidence
Its two-column presentation, compact letterforms, breathing and accent practices, enlarged initials, and marginal reading aids belong to the material history of a medieval Gospel book. The artifact is distinct from Codex Seidelianus I in shelfmark, contents preserved, and copying history.
Direct biblical contents
The surviving book or fragments physically preserve John 1, Matthew 28 or its historical interpretation.
Evidentiary boundary
The shared “Seidelianus” label can cause confusion with GA 011, but the two are separate codices. GA 013 is not complete, its modern provenance has gaps, and its ninth-century readings must be weighed with earlier and geographically diverse witnesses.
Follow the evidence from discovery to debate
Move through the find in a deliberate order: establish its provenance, examine the surviving object, place it in time, and then weigh the scholarly interpretation.
How the find came to light
The manuscript bears the Seidelianus name because of its association with Andreas Seidel, but it followed a different route from the Harley codex. Its present Cambridge shelfmark fixes its identity and prevents the shared collector name from collapsing two physical artifacts into one record. This dossier follows the artifact from its probable production setting through named owners, libraries, dispersal, reuse, damage, or rebinding to the present shelfmark. That chain matters because a familiar nickname may derive from a collector or modern city rather than the ancient place where the book was copied. Catalog numbers, leaf counts, and repository identities are therefore treated as evidence, not administrative trivia. Modern photographs and facsimiles increase access but do not erase the difference between the original parchment, an older printed plate, and a digital surrogate. Where the early route is unknown, the record leaves it unknown instead of turning later custody into an invented excavation story. The result is a provenance account that explains both survival and loss, including why some passages are complete, fragmentary, overwritten, fire-damaged, rebound, or divided among institutions.
What you are looking at
A Greek parchment Gospel codex written in majuscule script, with substantial portions of all four Gospels. The surviving book is incomplete and includes chapter apparatus, punctuation, corrections, and lectionary markings that expose how it functioned after copying. Its two-column presentation, compact letterforms, breathing and accent practices, enlarged initials, and marginal reading aids belong to the material history of a medieval Gospel book. The artifact is distinct from Codex Seidelianus I in shelfmark, contents preserved, and copying history. The dossier reads the codex as a manufactured object: writing support, ink, ruling, columns, line count, script, quire sequence, decoration, correction, marginalia, and binding all help identify what survives. Biblical words are not detached from the page that carries them. A chapter number can reveal navigation, a lectionary sign can reveal public reading, a correction can reveal comparison with another exemplar, and a palimpsest surface can preserve two different libraries on one sheet. The selected hero image is explicitly a manuscript page or fragment from this object, with a public-domain source record; it is not a generic medieval scene. Because a single photographed folio cannot represent every hand or book in a codex, the caption identifies its limited role and the text avoids projecting that page’s condition across the whole artifact.
Where it belongs in history
The display date “Ninth century AD” summarizes palaeographic, codicological, art-historical, or documentary judgments rather than a date printed by a modern machine. Script style, page design, pigments, textual divisions, related dated hands, and custodial evidence can narrow a range, but they rarely identify a precise day of copying. The manuscript belongs to the long material transmission of John 1:35–42. That connection is direct at the level of preserved biblical text or sustained visual interpretation, yet chronological distance remains explicit: a medieval witness shows what a community copied and read, not the physical page first written by a biblical author. Dating also remains independent of textual quality. A later book can preserve an earlier reading, while an early fragment can contain a scribal mistake; responsible comparison weighs relationships passage by passage.
Consensus, questions, and debate
The witness contributes to the later majuscule evidence for the Gospels and contains a largely Byzantine text with individual departures. Its corrections and liturgical signs are as important for reception history as isolated variants are for textual criticism. The shared “Seidelianus” label can cause confusion with GA 011, but the two are separate codices. GA 013 is not complete, its modern provenance has gaps, and its ninth-century readings must be weighed with earlier and geographically diverse witnesses. The narrow secure claim begins with physical identity: this manuscript or fragment exists, preserves the stated passages or book collection, and belongs within the documented date and custodial range. Broader conclusions—about an exemplar, textual family, translation technique, patron, workshop, or theological program—are interpretations that must remain attributable and revisable. The INTF registry or an equivalent institutional shelfmark standardizes identity, while manuscript-specific cataloging supplies physical facts and scholarly bibliography frames comparison. No record describes a manuscript as “proving the Bible.” Textual witnesses instead allow readings to be compared across time and place, expose corrections and variants, and show the extraordinary labor through which Scripture was transmitted. Where the object is incomplete, dispersed, overwritten, damaged, or supplemented, those conditions are part of the conclusion rather than inconveniences hidden from the reader.
The biblical record beside the artifact
The surviving manuscript directly preserves or interprets John 1:35–42; Matthew 28:16–20. It therefore supplies physical evidence for the copying, translation, organization, reading, or visual reception of these biblical texts in its own historical period.
John 1:35–42
35¶ Again the next day after John stood, and two of his disciples;
36And looking upon Jesus as he walked, he saith, Behold the Lamb of God!
37And the two disciples heard him speak, and they followed Jesus.
38Then Jesus turned, and saw them following, and saith unto them, What seek ye? They said unto him, Rabbi, (which is to say, being interpreted, Master,) where dwellest thou?
39He saith unto them, Come and see. They came and saw where he dwelt, and abode with him that day: for it was about the tenth hour.
40One of the two which heard John [speak], and followed him, was Andrew, Simon Peter’s brother.
41He first findeth his own brother Simon, and saith unto him, We have found the Messias, which is, being interpreted, the Christ.
42And he brought him to Jesus. And when Jesus beheld him, he said, Thou art Simon the son of Jona: thou shalt be called Cephas, which is by interpretation, A stone.
A responsible historical conclusion
Codex Seidelianus II (GA 013) gives Bible readers a concrete encounter with transmission rather than an abstract assertion that a text somehow survived. The page shows a scribe choosing a support, ruling columns, forming letters, navigating books, correcting mistakes, and preparing Scripture for reading or study. Its most responsible contribution is resolution: it can identify which passage is physically present, how the book was organized, which later hands intervened, and where uncertainty begins. That evidence supports careful confidence without pretending that all copies are identical or that material survival settles authorship, inspiration, or every historical claim within the text. Connected Bible pages make the relationship discoverable in both directions, while the institutional sources let readers revisit the catalog, images, and scholarly framework for themselves.
