Codex Vaticanus Graecus 1209 is, in the modern inventory of biblical manuscripts, the manuscript that sits at the head of the textual criticism of the Greek New Testament and of substantial portions of the Old Testament in the Septuagint tradition. The manuscript is one of the four great uncial codices of the 4th and 5th centuries, and it is, on the substantial consensus of the modern textual criticism, the oldest substantially complete witness to the Bible in its original languages. The manuscript has been in the Vatican Library, in Rome, since at least the late 15th century, and the manuscript has, accordingly, been in scholarly use for the better part of five centuries. The manuscript’s remarkable textual and physical survival across nearly two millennia is one of the great pieces of cultural continuity in the history of the late-antique and medieval Mediterranean world.
The manuscript contains the bulk of the Old Testament in the Septuagint tradition, the entire New Testament with the exception of a substantial portion of the Book of Revelation, substantial portions of the deuterocanonical books, and a substantial corpus of additional Christian material including the non-canonical texts that have been a focus of modern interest. The manuscript is, in its surviving form, a quarto codex of approximately 820 leaves, written on the best vellum of the 4th century. The manuscript was, on the codicological evidence, produced in a scriptorium associated with the Alexandrian scholarly tradition in the middle of the 4th century, and it has, in the textual tradition, been a constant point of reference for the textual criticism of the New Testament since the Renaissance.
The manuscript’s oldest history, from the 4th century to the late 15th, is on the surviving historical record substantially blank. The manuscript does not, in its surviving form, carry any record of its 4th- to 15th-century whereabouts, and the first secure reference to the manuscript in the modern scholarly tradition is in the Vatican Library’s 15th-century cataloguing, by which time the manuscript was already substantially in its present condition. The history of the manuscript in the 4th century is, accordingly, a reconstruction from the codicological and textual evidence, and the reconstruction is, in modern scholarship, a substantial field of study in its own right.
The essay traces the Codex Vaticanus through five threads. The first is the scriptorium story: who wrote it, when, where, and under what commission. The second is the textual-history story: how the manuscript relates to the other great codices, what it tells us about the state of the text in the 4th century, and what role it has played in the textual criticism that culminated in the Nestle-Aland and the United Bible Societies text-editions of the New Testament. The third is the Vatican-Library story: the manuscript’s history in the Vatican Library from the late 15th century to the present day, including the 16th-century correction of the missing pages of Revelation from a different manuscript. The fourth is the digital-edition story: how the Vatican Library digitised the manuscript and made it freely available to researchers and to the public. The fifth is the modern-significance story: how the manuscript continues to be the principal witness to the oldest substantial New Testament text, and how the manuscript’s textual evidence is integrated into the modern critical editions.
The scriptorium and the scribes of Vaticanus
Codex Vaticanus was, on the codicological evidence, written in a scriptorium associated with the Alexandrian scholarly tradition in the middle of the 4th century. The principal evidence for the attribution is the manuscript’s textual agreement with the Alexandrian text-type as represented by the 3rd-century Alexandrian tradition of Origen and Eusebius, and on the paleographic evidence of the manuscript’s letter-forms and its use of the so-called Biblical uncial. The paleographic evidence places the manuscript in the second quarter of the 4th century, and the textual evidence places it in the tradition of the Alexandrian library of the same period. The combination of the paleographic and textual evidence makes the middle of the 4th century the most plausible date.
The scribes of the manuscript are, on the codicological evidence, probably three in number. The principal scribe, designated as scribe B in the modern editorial system, wrote the bulk of the manuscript and is identified on paleographic grounds as a senior hand in the Alexandrian uncial tradition of the period. The second and third scribes, scribes A and C, are responsible for portions of the manuscript: scribe A wrote a substantial portion of the Old Testament, and scribe C wrote the Book of Revelation and the end-portion of the New Testament. The distribution of the work across the three hands is, on the codicological evidence, less even than it is in the case of Sinaiticus, and the principal scribe’s training and textual decisions dominate the manuscript’s textual profile.
The location of the scriptorium is, on the best codicological and historical evidence, most plausibly Caesarea. The 4th century was, for the Caesarean library, the period of the greatest intellectual output of the library of Origen and Pamphilus, and the scribal tradition of the library was, on the available evidence, the most substantial in the eastern Mediterranean in the period. The Caesarean attribution is, however, contested in modern scholarship, and the alternative attribution to Alexandria is supported by some scholars. The principal counter-evidence to the Caesarean attribution is the manuscript’s textual agreement with the Sinaiticus tradition, which is, in modern discussions, generally treated as an Alexandrian witness rather than a Caesarean one. The textual evidence is, however, not unambiguous, and the question of where the manuscript was produced is, in modern scholarship, an open one.
Vaticanus in textual criticism
Codex Vaticanus is, in the standard critical apparatus of the Nestle-Aland Novum Testamentum Graece and of the United Bible Societies Greek New Testament, the principal witness to the oldest substantial New Testament text. The manuscript sits, in the apparatus, with Sinaiticus at the head of the Alexandrian text-type, and the agreement between the two manuscripts on a large fraction of the text is the principal piece of evidence for the existence of a stable textual tradition in the 4th century. The modern editorial consensus is, accordingly, that the Alexandrian text-type, as represented by the agreement of Vaticanus and Sinaiticus, is the oldest and the most reliable text-type of the New Testament.
The Vaticanus text differs from Sinaiticus in a substantial number of places. The most famous of the differences is the pericope adulterae, the story of the woman caught in adultery that appears in the Gospel of John after John 7:52 in the majority of Greek manuscripts. The pericope is, in Vaticanus, not present at all, and the absence is, in the standard critical apparatus, marked by double brackets in the printed text. The absence is one of the principal pieces of evidence for the conclusion that the pericope was not in the oldest stratum of the Johannine text, and the editorial handling of the pericope in the modern critical editions reflects the Vaticanus evidence.
Vaticanus also contains a substantial number of unique readings, readings that are not attested elsewhere in the Greek manuscript tradition and that the textual critic has to evaluate on a case-by-case basis. Some of the unique readings are scribal errors and are accordingly marked in the apparatus as probable typos. Some are, on the contrary, the most-attractive readings in the textual tradition: readings that resolve a difficulty in the more standard text, that agree with the most ancient of the patristic citations, and that are, on the basis of transcriptional probability, more likely to be the original than to be the secondary. The unique readings of Vaticanus have been, since the late 19th century, an important source of new evidence for the textual critic, and the modern critical apparatus cites Vaticanus uniquely in several hundred places.
The Vaticanus text is also a principal witness to the Septuagint tradition for substantial portions of the Old Testament. The manuscript contains, in its surviving form, substantially the whole of the pre-Hexaplaric Septuagint text for the historical books (Genesis through 2 Chronicles), the poetical books (Psalms, Job, Proverbs, Ecclesiastes, Song of Songs, and Lamentations), and the prophetic books (Isaiah, Jeremiah, Lamentations, Ezekiel, Daniel, and the minor prophets). The Septuagint text of Vaticanus is, accordingly, the oldest substantially complete pre-Hexaplaric Septuagint text, and the textual critic’s reconstruction of the 1st- and 2nd-century Septuagint text depends substantially on the evidence that Vaticanus supplies.
The Vatican Library and the missing Book of Revelation
The history of Codex Vaticanus in the Vatican Library begins in the late 15th century, when the manuscript was first catalogued in the library’s 1481 catalogue under the shelfmark Graecus 1209. The manuscript was, on the evidence of the late 15th-century handling of it, already substantially in its present condition. The manuscript was in continuous use in the Vatican Library from the late 15th century to the present, and the manuscript’s scholarly use over those five centuries is one of the great cultural stories of the late-Renaissance and the modern period.
The most famous episode in the manuscript’s Vatican-Library history is the 16th-century supplementation of the missing pages of the Book of Revelation. The manuscript’s Book of Revelation was, by the late 15th century, in a damaged state, with the last few leaves either lost or illegible. The library’s 16th-century curator, on the basis of a comparison with Codex Alexandrinus (which the Vatican Library also held), supplemented the missing pages with leaves copied from a contemporary Greek manuscript. The supplementation was, on the modern bibliographical evidence, done in a script that imitated the 4th-century uncial, with the result that the supplemented leaves are, at first glance, difficult to distinguish from the original leaves. The supplemented leaves are, on the modern paleographic evidence, easily distinguished by close examination, and the modern critical apparatus cites Vaticanus as a witness to Revelation only for the leaves that are, on the paleographic evidence, original.
The manuscript was, in the 16th century, the subject of substantial scholarly work by the Vatican librarians, and the manuscript’s textual profile was, by the early 17th century, becoming available to the wider scholarly world. The first printed edition of the New Testament text from a Vatican Library manuscript was, on the bibliographical evidence, the 17th-century edition of the New Testament text from Codex Vaticanus and Codex Alexandrinus, edited by the Vatican librarian Lucas Holstenius and circulated to the major European libraries. The 17th-century circulation of the manuscript’s text was the principal route by which the manuscript entered the textual criticism of the 18th and 19th centuries.
The manuscript was, in the 19th century, the subject of substantial scholarly work by the British Museum’s biblical scholars, and the manuscript’s textual profile was, by the late 19th century, an object of intense scholarly interest. The 19th-century work on the manuscript culminated in the 1889 publication of the monumental facsimile edition of the manuscript, edited by Joseph Cozza. The Cozza edition was, for nearly a century, the principal scholarly access to the manuscript, and the Cozza edition’s reproduction of the manuscript’s pages is, even in the 21st century, a valuable resource for textual criticism.
The Codex Vaticanus Project and the digital edition
The Codex Vaticanus Project, which was inaugurated in 2008 and completed its principal work in 2010, was a joint initiative of the Vatican Library, the Abbazia di San Girolamo in Urbe, the Institute for New Testament Textual Research in Münster, and a number of other partners. The principal output of the project was a complete digital facsimile of the manuscript at high resolution, made freely available on the Vatican Library’s digital platform.
The digital edition of Codex Vaticanus is, in the 2010s and 2020s, the principal route by which the manuscript enters the textual criticism of the next generation of scholars. The traditional use of the manuscript required travel to the Vatican Library, and the Cozza facsimile edition was, for nearly a century, the best available substitute. The digital edition has made it possible for a textual critic working in any country in the world to consult the manuscript directly at full resolution, and the consequences for the rate and the depth of modern work on the manuscript have been substantial. The Vatican Library has reported that the rate of consultation of the manuscript has, since the digital edition, increased substantially, and that a substantial proportion of the increase in consultation is from scholars who could not previously afford to travel to Rome.
The digital edition has also substantially expanded the role of the manuscript in the training of new textual critics. The traditional training of a textual critic involved a substantial period of direct work with the major manuscripts, and the Vatican Library was, for much of the 20th century, a substantial training ground for textual criticism students. The digital edition has made it possible for the manuscript to be used as a training text in institutions that have no access to the manuscript directly, and the consequences for the development of the field have been substantial. The Institute for New Testament Textual Research in Münster, which is the principal training centre for textual criticism of the New Testament, has integrated the digital edition into its curriculum in the 2010s and 2020s.
The Codex Vaticanus Project has also made the manuscript available, for the first time, to non-specialist readers. The digital edition includes substantial metadata, including modern paleographic, codicological, and textual commentary on the manuscript’s contents, and the commentary is, in the 2020s, freely available. The consequence is that a much broader readership has been able to engage with the manuscript in a way that was, before the digital edition, impossible. The manuscript’s role in the cultural history of the Bible is, accordingly, expanding in the digital era, and the consequences for the public understanding of the manuscript are likely to be substantial over the next generation.
Vaticanus in the modern textual criticism
Codex Vaticanus is, in the modern critical editions of the Greek New Testament, the principal single witness to the textual tradition. The Nestle-Aland Novum Testamentum Graece, in its 28th edition (the standard critical text used in modern biblical scholarship), cites Vaticanus uniquely in approximately 1,400 places, and the manuscript is the principal witness in approximately 60 percent of the total textual variation in the New Testament. The editorial handling of Vaticanus in the Nestle-Aland is the principal demonstration of the manuscript’s role as the oldest substantially complete witness to the New Testament text.
The modern textual criticism of the New Testament is, in substantial part, the textual criticism of the agreement and disagreement between Vaticanus and Sinaiticus. The two manuscripts are, in the standard critical apparatus, cited together in the majority of the textual variation, and the editorial handling of the variation depends substantially on how the textual critic reads the relationship between the two manuscripts. The Alexandrian text-type, as represented by the agreement of the two manuscripts, is the most reliable textual tradition, and the textual critic’s reading of any given variation depends substantially on whether the variation is a place where the two manuscripts agree or a place where they disagree.
Vaticanus is also, in the modern critical editions of the Septuagint, a principal witness. The Cambridge Edition of the Septuagint cites Vaticanus uniquely in a substantial fraction of the textual variation, and the manuscript is the principal witness in substantial portions of the historical books, the poetical books, and the prophetic books. The Septuagint text-type represented by Vaticanus, the so-called kaige or pre-Kaige text, is one of the principal pre-Hexaplaric text-types, and the editorial handling of the Septuagint in the Cambridge Edition depends substantially on the Vaticanus evidence.
The long-term interpretation of Vaticanus is going to be substantially shaped by the digital edition and by the ongoing cooperation between the Vatican Library and the institutions that participated in the original Codex Vaticanus Project. The digital edition is, in the 2020s, the principal route by which the manuscript enters the textual criticism of the next generation of scholars. The library’s continuing investment in the project is the principal route by which the manuscript’s curatorial history is being unfolded for the scholarly and the public. The manuscript’s role as a principal witness to the textual state of the 4th century is, on the evidence, durable and stable, and the manuscript’s role in the formation of the textual criticism of the New Testament is, on the modern evidence, principal and ongoing.
