Vaticanus Distigme-obelos Symbols Marking Added Text, Including 1 Corinthians 14.34–5

The two-dot-plus-bar ‘distigme-obelos’ symbols in Vaticanus signal added text. Five characteristic features distinguish their obeloi from paragraphoi. Like scribe B's LXX obeloi, all eight distigme-obelos symbols mark the location of added text. A gap at the exact location of a widely recognised, multi-word addition follows every distigme-obelos except one with distinctive downward dipping strokes. The Vaticanus Gospels are so early that they have virtually no high stops, a feature older than even 75. Consequently, they contain none of these additions, but the Vaticanus epistles have high stops throughout and contain their one distigme-obelos-marked addition, 1 Cor 14.34–5. Contemporaneous LXX G has corresponding distigmai.


Introduction
This article publishes for the first time all eight instances in codex Vaticanus B (henceforth, Vaticanus) where a distigme  identifying a textual variant is combined with a bar that has five specific characteristics.  It argues that just as bar-shaped obeloi in the Vaticanus prophets identify the locations of blocks of added text, so do all eight distigme-obelos symbols in the Vaticanus NT. Milne, Skeat and Canart ascribe each Vaticanus LXX book with obeloi and asterisks to the same scribe who penned the Vaticanus NT, scribe B.  On the line to the right of each distigme-obelos symbolexcept one with a downward stroke from both dots and the bar, indicating a different handis a gap (henceforth, 'following gap') in the text at the exact location of a multi-word block of text widely recognised as not original, but added later (henceforth, 'added text'). Only the original scribe could have put these gaps in the text. The distigme at Luke . matches the original Vaticanus ink. Therefore, since obeloi mark the location of added text, their conjunction with a gap at the exact location of added text is most naturally explained if scribe B penned these symbols and left the following gap to mark where text was added.
It appears that all studies of distigmai in Vaticanus agree that distigmai correlate closely with the location of textual variants.  Probability tests confirm this correlation to a high degree of reliability.  Ever since Canart concluded that fifty-one distigmai match the apricot colour of the original Vaticanus ink on the same page and identified traces of original ink protruding from some evidently re-inked distigmai,  there has been a growing acceptance that at least the original-ink-colour distigmai date to the fourth century and mark the location of textual variants.  Other surviving NT manuscripts contain a variant reading in over  per cent of these fifty-one distigme locations.  This article begins by establishing the use of distigmai near the time of Vaticanus in the fourth-or fifth-century LXX G. It then provides evidence that scribe B repeatedly left comments explaining that obeloi signify added text. After analysing the eight distigme-obelos symbols in the Vaticanus NT, it argues from the form and function of their characteristic bars that it is highly improbable these eight bars are simply paragraphoi unrelated either to the distigme or to the added text at the exact point of the following gap.
The article concludes by providing an explanation why the Vaticanus Gospels do not include any of the blocks of added text their five distigme-obelos symbols mark, but the Vaticanus epistles do include the block of added text their one distigme-obelos marks. The contrast between the presence of high stops throughout the Vaticanus epistles and their virtually complete absence from the Vaticanus Gospels indicates that practically all the Vaticanus Gospels' text preceded the adding of high stops and so is earlier than the Vaticanus epistles' text. It is even earlier than   's text, which has high stops throughout. This vindicates scholarly judgement that the Vaticanus Gospels' text is earlier than its epistles' text.  Its text is so early that it preceded all five of its distigme-obelos-marked additions, hence their omission from its Gospels.
This study demonstrates that scribe B was a careful textual critic who identifies  Cor .-, the only Bible passage silencing women in the church, as added text. Vaticanus provides early and credible judgement in what is widely regarded as the most important NT manuscript that vv. - were not in the body text Paul's original letter, but are a later addition. This is important theologically since it offers a resolution to the notorious difficulty of reconciling vv. - with Paul's many affirmations of women in vocal ministry and their equal standing with men in Christ.

Swanson The most extensive early hexaplaric manuscript known, the fourth-or fifthcentury codex Colberto-Sarravianus,  called LXX G (henceforth, 'G'), also marks the location of textual variants using distigmai. For example, the distigme at G  B (Deut .) marks a textual variant between G and the LXX (see Fig.  the original text of Vaticanus at  A,  B (πʹ εβρʹ in original ink),  A,  C and  B,  locations with no obelos. Each signals text not in the MT.  Their original apricot colour, their lack of obeloi, and the same explanation in apparently original ink with an obelos at  A,  make scribe B the most likely originator of the Vaticanus ου κʹ πʹ εβρʹ abbreviations. All this indicates that scribe B knew enough about the Hebrew MT to mark where the LXX added text to the MT, even where Vaticanus' exemplar had no obelos. It also indicates that scribe B faithfully copied the exemplar without even adding obeloi.
The obelos was the standard symbol for spurious text in ancient Greek literature.  Indeed, it was its 'first and most important' text-critical symbol.  F. Schironi argues it has 'a rather unequivocal meaning' so the reader knows that an obelised 'line is considered spurious, and this is an unambiguous piece of information'.  Basil (ca. -), Hex.

. The Eight Vaticanus Distigmai Adjacent to a Characteristic Bar
Eight bars in the Vaticanus NT adjacent to a distigme correspond in shape to scribe B's LXX obeloi but are graphically different in two respects from the Vaticanus paragraphoi that occur at random adjacent to a distigme. First, they protrude into the margin,  on average, . mm compared to a sharply contrasting . mm for the twenty undisputed paragraphoi. Their greater extension into the margin brings them closer to the adjacent distigme, associating them with the standard Vaticanus symbol marking the location of textual variants. The characteristic bar adjacent to a distigme at the interface of  Cor . and  extends  mm into the margin. In contrast, the seventy-five other bars in  Corinthians extend, on average,  mm into the margin, and only one of these seventy-five extends  mm into the margin ( B).  Greater extension into the margin is their primary graphic distinction, but they also average . mm long compared to the remaining twenty bars' . mm average length. Thus, not only do they extend on average almost twice as far into the margin as these twenty undisputed paragraphoi, they are, on average, almost one third longer, as the characteristic bars near paragraphoi in Figs. - illustrate.
Of the twenty-eight bars following a distigme, only these eight combine noticeably further extension into the margin with noticeably greater length.
The function of the eight bars in question also evidently differs from paragraphoi. Each occurs at the location of a widely acknowledged block of added text. The NA  apparatus identifies a multi-word textual variant at least three words long at each of these eight locations. In each case, at least two words are completely different from the Vaticanus text, not just different forms of the same word. 'Multi-word variant' entails this characteristic henceforth.
NA  's apparatus is an appropriate basis for assessing whether distigme-obelos symbols are text-critical symbols since NA  identifies 'variants of text-historical relevance'.  Multi-word additions have important text-historical relevance. Scribe B marked added text in the LXX prophets with obeloi and explanations  'The margin' is at the far-left edge of letters on the margin, excluding τ υ Φ and ψ, whose vertical stroke is at the margin, and χ, which straddles the margin. The VaticanusLSU font is available from www.linguistsoftware.com/ntmssu.htm.  Excluding the bar at  B since it is noticeably lower than all the other eight paragraphoi on -; it does not match the surrounding text's ink colour or stroke thickness, but rather the colour, graininess and stroke thickness of the ink of the adjacent, later, marginal addition; and, unlike every other paragraphos bar in  Corinthians, it does not underscore the first letter of its line. Contrast the paragraphos five lines later, at  B, that crosses a φ's descender, just as paragraphoi cross the descender of all eight adjacent φs (  P H I L I P B . P A Y N E that text was added. This proves he or she  regarded blocks of added text as significant. B. Ehrman, as others, argues that 'even readings that are not attested in the fragmentary remains of the ante-Nicene age … are by and large best understood as deriving from documents of the first three centuries … The vast majority of all    textual variants originated during … the second and third centuries.'  This highlights the value of the NA  apparatus for identifying early textual variants. Following all eight distigmai adjacent to a characteristic bar, except the one whose downward dipping strokes indicate that a different scribe penned it, there is a gap either in the middle or at the end of the line of text at the exact location of a multi-word, widely acknowledged block of added text. By contrast, a gap occurs in only twelve of the twenty lines following a distigme adjacent to an undisputed paragraphos ( per cent).  Thus, both their characteristic form and apparent function distinguish these eight bars from paragraphoi and support viewing them as distigme-obelos symbols. The following analysis, however, refers to them neutrally as 'characteristic bars' until concluding that they are distigme-obelos symbols.
Following five of the seven apparently original characteristic bars, scribe B left a mid-line gap at least one letter wide at the exact location where other manuscripts add text. This far exceeds the average in Matthew of a correspondingly wide, mid-line gap only once every . lines of text.  The other two bars are at the location of a block of added text at a gap at the end of a line that is at least one letter shorter than the average line length in that column.
Following are images of all eight distigmai adjacent to a characteristic bar (Figs. -). Each figure's title gives that passage's verse reference and its Vaticanus page number and column. The triangle in each image identifies the exact location of widely recognised, added text. After each image are the added text and the manuscripts NA  , NA  , and/or Swanson lists with this addition or providing evidence of it.
.   f h q sy c.p.h bo mss (a vg mss mae)      διὰ τὸ ἐλέγχεσθαι αὐτοὺς ἐπ' αὐτοῦ (διότι ἠλέγχοντο ὑπ' αὐτοῦ Ε) μετὰ πάσης παρρησίας· μὴ δυνάμενοι οὖ<ν> ἀντοφθαλμεῖν (ἐπειδὴ οὐκ ἠδύναντο ἀντιλέγειν Ε) τῇ ἀληθείᾳ D h t w sy hmg (mae) Acts . is the only one of these eight whose following line of text contains no noticeable gap. Both dots and the bar have downward strokes that are strikingly different from the other seven and distinguish it from the handwriting of scribe B. Consequently, it is highly doubtful this distigme and characteristic bar were in the original text. Furthermore, the added text is not as memorable as any of the other seven. Pamphilus and Eusebius circulated Origen's edited LXX text with obeloi and asterisks extensively in Palestine in the fourth century, so its readers, and any reader familiar with the obelos, including the obeloi in the Vaticanus prophetic books, would know that the obelos identifies the location of added text.  Presumably, one such scribe or reader understood that a distigme plus an obelos-shaped characteristic bar marks added text and inserted this one at Acts . to mark that another manuscript adds text here.   Should one trust scribe B's distigme-obelos marking .- as added text? NA  and manuscript evidence confirms a block of added text at the gap after every other scribe B distigme-obelos. To judge from the range of manuscripts reflected in those textual variants and original-ink-colour distigme variants and by the Vaticanus Gospel's early text, scribe B had access to far more early manuscript text than is now extant, enough to trust scribe B's judgement on .-.  Transcriptional probability also argues that these verses' differing locations result from a marginal gloss, not transposition. 'The reading which can most easily explain the derivation of the other forms is itself most likely the original.'  No Pauline manuscript transposes any other passage nearly this large  Parker, Introduction, , . 'Gloss', however, avoids misunderstanding since some writers define 'interpolation' as deliberate polishing of the body text, but a 'gloss' as text written in the margin and later inserted into the text by copyists, as seems more likely here. this far without an obvious reason.  The most detailed attempt to find long transpositions in 'Western' manuscripts identifies only three instances. The longest moves a seven-or eleven-word benediction three verses forward for the obvious reason, to make 'an apt conclusion to the letter'.  A thirty-six-to fortyword transposition five verses away with no obvious reason is unprecedented in any Pauline manuscript. It was conventional, however, for scribes to copy text in the margin, including reader comments, into the body text, as U. Schmid has shown.  Vaticanus itself exemplifies this convention. Seventeen of its twenty instances of readable small uncial text in the margins of Matthew appear in the body text of most later manuscripts.  Something conventional is far more likely to occur than something unprecedented. One early copyist apparently inserted vv. - from the margin into the text after v. , which gave rise to their 'Western' location. Another early copyist apparently inserted vv. - after v. , which gave rise to their usual location.  This is the only explanation of this text's two locations congruent with common scribal practice. A marginal gloss far better explains both locations of vv. - than does an unprecedented transposition for no obvious reason. It is doubtful that vv. - could fit in a papyrus margin if written in Paul's 'large hand'.  At least sixty-two textual studies argue that .- is a later addition.  J. Fitzmyer notes that 'the majority of commentators today' regard vv. - as a later addition.  K. Haines-Eitzen affirms this of '[n]early all scholars now'.  Verses - silence women in church three times without any qualification. Chapter , however, guides how women should prophesy, and chapter , vv. ,  (x),  and  affirm 'all' speaking in church. Popular resolutions of this apparent contradiction limit .-'s demand for silence only to disruptive chatter or, recently contrived, only to judging prophecies. These resolutions should be rejected since they permit speech v.  prohibits, namely asking questions from a desire to learn. In light of substantial evidence that vv. - were originally a marginal gloss and no evidence that any other block of text was added at this gap,  these verses are the obvious candidate for the multi-word addition signalled by this distigme plus characteristic bar.
In six of the eight cases under discussion, the addition is to the line of text the bar underscores. Paragraphoi also underscore a line of text when the paragraph break occurs within that line. When a paragraph ends at the end of a line, a paragraphos underscores that line, marking the interface between the paragraphs. Likewise, two characteristic bars adjacent to distigmai underscore the last line of the original text and mark the interface between original text and a later addition. Luke . ends with a five-letter gap (see Fig. ). The characteristic bar marks the interface between the original text and the later addition, 'For many are called but few are chosen.' Similarly, the two-letter gap compared with the next line  at the end of  Cor . marks the interface between the original text and the widely recognised addition, 'Let women be silent in the churches … for it is a disgrace for a woman to speak in church' (vv. -) (see Fig. ). A line preceded by a bar but followed by a distigme also separates John . from John . and marks the interface between the original text and the Pericope Adulterae.
All eight additions are arguably important theologically  and include some of the passages most widely regarded as later additions: 'Jesus said to them' (Matt  J. Fitzmyer, First Corinthians (AB; New Haven: Yale, ) , citing twenty scholars, including, Cope, Delling, Fuller, Keck and Roetzel.  Haines-Eitzen, Palimpsest, .
 The addition of διδάσκω is before the high stop, so precedes this gap, is not a multi-word addition, is not listed in NA  , and is apparently in no Greek manuscript before the ninth century. Furthermore, since its earliest occurrences are in 'Western' texts, it is doubtful that any scribe would have noted the addition of διδάσκω but not the far more obvious and note- In those days' (Acts .), 'Because it was to convict them concerning him with all boldness, since they were not able to face the truth directly' (Acts .), and 'Let women be silent in the churches … for it is a disgrace for a woman to speak in church' ( Cor .-). The content of the addition is easily memorable in every case except the one with distinctive downward strokes at Acts .. Scribe B, who also marked text the LXX added to the MT with similarly shaped obeloi, was apparently aware of these seven memorable NT additions, left a gap at the exact point they begin, and highlighted their location with a distigme and characteristic bar.

. Are These Characteristic Bars Paragraphoi or Obeloi, or Do They
Have a Dual Function?
C. Niccum writes that the bars following distigmai 'date to the fourth century' but are paragraphoi, not obeloi.  He, Miller and Shack, although acknowledging that distigmai mark the location of textual variants, deny that there is any association between any bar and the adjacent distigme, and they deny that either these bars or the following gap mark the location of added text.  Shack asserts that it 'is only a coincidence' that these bars are followed by gaps that always occur at the exact location where multi-word blocks of text were added.  Even if there were no graphic differences between these eight bars and paragraphoi, their combination with distigmai could signal a more specific purpose just as other combined symbols do in Vaticanus. For example, a baseline dot functions like a comma at  A and , but added to a high stop it signifies a section break at  B. Similarly, a short slash descending from left of the middle of a paragraphos specifies a section or book break.  Although their component parts individually convey distinct meanings, together these composite symbols convey a specific meaning that incorporates some of the meaning of both. Similarly, scribe B may have combined these distigmai with bars to convey a specific meaning.
There are, however, graphic differences between these eight bars and the other twenty bars adjacent to a distigme. All eight combine noticeably greater extension into the margin with noticeably greater length than the other twenty. Functionally also, all eight mark the location of widely acknowledged, multiword, added text, which is the purpose of obeloi. This extraordinarily consistent pattern supports the identification of these characteristic bars as obeloi.  P H I L I P B . P A Y N E There are various possible relationships between the eight characteristic bars and obeloi and/or paragraphoi. Some of these blocks of added text occur at a natural paragraph break. Four of the seven gaps coincide with a paragraph break in NA  , and three with a paragraph break in the UBS  .  Only the gap at the interface of  Cor . and  is in the middle of an NA  and UBS  sentence. A. Lavrinovi ca concluded, however, that every manuscript up to the twelfth century has a break at the beginning of v. , with the possible exception of the ambiguous   .  This NA  and UBS  paragraph break, therefore, is not where virtually any early scribe understood it should be. Vaticanus has a high stop after v. , and all early 'Western' Greek text scribes treat vv. - as a unit. Scribe B may have even regarded all seven gaps as occurring at a paragraph break. Or scribe B may have positioned the first three characteristic bars in the normal paragraphos location because they are all at natural paragraph breaks, then retained the same position for the others to keep them consistent.
By extending these eight bars on average almost twice as far into the margin as the other twenty bars following a distigme,  scribe B associated the bar with the distigme marking the location of a textual variant. The obelos shape of the long bar and each gap at the exact location of a block of widely acknowledged added text strongly indicate that the bar does not function merely as a paragraphos, but also or especially as an obelos.
Four factors explain why scribe B did not simply use the usual LXX obelos position entirely in the margin to mark these blocks of text added to the NT. First, that position had already been taken by the customary Vaticanus distigme marking where these Greek variants occur. Second, this Vaticanus LXX obelos position marks text actually in Vaticanus as added, but the added words are not in the Vaticanus NT text, except in the last case.  Third, that obelos position marks differences between the LXX and MT, not between Greek texts. Fourth, readers associated hexaplaric marginal symbols with the LXX, not the NT.
A dual purpose of () marking the location of added text () at a paragraph break would explain the paragraphos position of the NT obeloi. An additional benefit (or alternative explanation) of this position is that putting an obelos below and to the right of a distigme is a logical way to specify the location of a specific kind of textual variant, the same kind scribe B's obeloi identify in the LXX, blocks of added text.

. How Strong is the Evidence that These Eight Bars are not Simply
Paragraphoi?
What is the statistical probability that in a random distribution all eight characteristic bars following distigmai would be at the location of a textual variant at least three words long in manuscripts cited in NA  's apparatus? Using Matthew as a conservative baseline, the probability that all eight Vaticanus lines would coincide with the location of a multi-word variant listed in NA  is  in .  = ,,,,.  Since distigmai mark the location of textual variants, however, lines following distigmai in Vaticanus are more likely to coincide with textual variants, including multi-word variants, than random lines are. So, this author compared the occurrence of multi-word variants at these eight distigmai adjacent to characteristic bars (eight of eight) to the twenty distigmai adjacent to undisputed paragraphoi (two of twenty).  The standard probability test shows that the likelihood of such a stark difference occurring at random is far less than one in ,.  This is over  times greater than the threshold needed to reject the null hypothesis. In this case, the null hypothesis is that characteristic bars adjacent to distigmai do not correlate with multi-word textual variants. This test result justifies distinguishing the eight characteristic bars from paragraphoi.
Furthermore, a gap follows all seven apparently original distigme-obelos symbols at the exact point where a multi-word addition begins. This identifies their location over sixteen times more precisely than simply somewhere in the line.  All this shows to a high degree of probability that these characteristic bars are not simply paragraphoi that merely by chance share the following five characteristic traits: . Each occurs immediately after a distigme. . Each extends noticeably further into the margin than most bars adjacent to distigmai.
 By the author's count NA  's apparatus contains only  multi-word variants in Matthew. Compared to the , Vaticanus lines in Matthew, this is fewer than one in . Vaticanus lines. Matthew is probably at the high end of how frequently multi-word variants occur because NA  , -, lists more papyri of Matthew (twenty-four) than of any other NT book except John (thirty). Furthermore, variant readings due to harmonisation, which are often multi-word, are more frequent in the synoptic Gospels than any other part of the NT. Accordingly, five of the eight multi-word variants marked by distigme-obelos symbols are in the synoptic Gospels, two are from Matthew, and three are inter-synoptic harmonisations.  The two are Mark . ( B) and Acts . ( B). Both bars are short, only about  mm long, and neither extends much into the margin.  For the details of this chi-square test, see www.pbpayne.com/wp-content/uploads/// Vaticanus-distigme-obelos-chi-square.pdf.  There are  letters in the  lines of Vaticanus  column A, Matthew's first column of narrative text, an average of . letters per line.
. Each is noticeably longer than most bars adjacent to distigmai. . Each occurs at the location of a widely recognised, multi-word addition. . A gap at the precise location of this addition follows all seven apparently original characteristic bars.
None of the other twenty bars adjacent to a distigme, which fulfils the first characteristic, shares more than two of the remaining four characteristics. Mere coincidence does not adequately explain the data. All eight characteristic bars occur at the location of the same kinds of additions that scribe B marked with similarly shaped obeloi where the LXX added text to the MT. Since these eight characteristic horizontal bars are distinguishable in both form and function from paragraphoi, since their primary function of identifying the location of blocks of added text is the standard function of obeloi, and since this is not a function of paragraphoi, they should be recognised as obeloi. Since a distigme identifies a textual variant, and since an obelos identifies a specific category of textual variant, text that was added after the original composition, 'distigme-obelos' is the most appropriate name for this symbol. This conclusion is compatible with the possibility that some or all distigme-obelos symbols, as a secondary function, mark a paragraph break and that this may have influenced the obelos position.
. Why does Vaticanus Include the Added Text Only after the One Distigme-obelos in the Epistles and Never in the Gospels?
 Cor .-, the text at the gap following the only distigme-obelos in the Vaticanus epistles,  is the only added text marked by a distigme-obelos to be found in the Vaticanus text. Why is the added text here, but never in the Gospels? A satisfying answer comes from a surprising source. 'There is nothing apparently more "minor" or "trivial" than a mere dot, and yet matters of significance can depend on one.'  High stops hardly ever occur in the Vaticanus Gospels, but they mark the end of sentences throughout the Vaticanus epistles.  Since scribe B copied both the Vaticanus Gospels and epistles, why this sharp contrast in use of high stops? The most natural explanation, and the only one congruent with a copyist's primary task, to reproduce the exemplar's text, is that the Gospels' exemplar(s) had virtually no high stops, but the epistles' exemplar(s) used high stops extensively, and scribe B copied both exemplars faithfully enough to preserve this difference. Canart agrees with this explanation.  The text of   (NA  , , third century) is remarkably similar to the corresponding text of Vaticanus throughout Luke and John.  Unlike the Vaticanus Gospels, however,   uses high stops extensively. Like the Vaticanus Gospels, none of the NT papyri NA  identifies as second-century (  ,   ,   ,   ) contains a high stop. Metzger and Ehrman write, 'the earliest manuscripts have very little punctuation',  and the Alands state, 'the original texts … naturally also lacked punctuation'.  The lack of high stops in the Vaticanus Gospels, therefore, indicates a text even earlier than   's text. It corroborates both halves of Metzger's judgement: 'Since B is not a lineal descendent of   , the common ancestor of both carries the … text to a period prior to AD -, the date assigned to   .  It also supports Pisano's affirmation 'of the text of B as an extremely reliable witness …, especially of the Gospels and Acts'.  The contrast in use of high stops between the Gospels and epistles in Vaticanus adds to other evidence that scribe B was careful to preserve the text of the Vaticanus exemplars. Only scribe B preserved obeloi and asterisks in the Vaticanus LXX text. As explained above (pp. -), the original-ink ου κʹ πʹ εβρʹ ('is not in the Hebrew') where there are no obeloi in the prophetic books shows that scribe B did not even add obeloi to the exemplar's text.  Scribe B preserved text its exemplars added both in the prophets and in  Cor .-, but marked these as later additions. In keeping with such faithful manuscript copying, it appears that scribe B faithfully copied the Vaticanus Gospels' exemplar with virtually no high stops but its epistles' exemplar with abundant high stops. This thesis, that scribe B faithfully copied a primitive text of the Gospels, explains both why the Vaticanus Gospels have virtually no high stops and why its text does not include any of the five blocks of added text its distigme-obelos symbols mark.
The Vaticanus Gospels' text is so early that it preceded each of these five additions. 

Conclusion
Distigmai in Vaticanus mark the location of Greek textual variants, as do some distigmai in the fourth-or fifth-century LXX G. Eight of the twenty-eight bars adjacent to distigmai are different from the other twenty in four respects: . They extend, on average, almost twice as far into the margin as the other twenty. . They are, on average, almost one third longer than the other twenty. . Each occurs at the location of a widely recognised, multi-word addition to the text. . All but one, with downward dipping strokes from both dots and the bar, indicating a different hand,  have a gap in the following line at the precise location of the addition.
None of the other twenty bars shares both the first two graphic differences, and only two of the other twenty bars are at the location of a multi-word textual variant.
Seven key facts support the conclusion that all eight of these characteristic bars adjacent to a distigme are obeloi marking the location of a block of added text: . A multi-word textual variant in NA  's apparatus occurs at all eight locations.
If all eight were simply paragraphoi, this conjunction would have to be mere coincidence. The standard statistical test result rejects the coincidence hypothesis to a degree of probability over  times greater than the normal threshold needed to reject this hypothesis. . Scribe B left a gap at the exact location of a widely acknowledged block of added text following every characteristic bar, except one that is evidently from a different hand. . None of the other twenty bars adjacent to a distigme combines as much extension into the margin and total length as any of the eight characteristic bars. . Scribe B used horizontal-bar-form obeloi in the Vaticanus LXX prophets to mark the locations of blocks of added text. Only the original scribe could have penned the obelos in the text of Isa ., and explanations that obeloi mark added text contain original Vaticanus ink. These lines of evidence confirm that scribe B understood that obeloi mark added text. . The eight long characteristic bars adjacent to distigmai resemble the shape of the  long horizontal-bar-form obeloi attributed to scribe B in the Vaticanus prophets. . The obelos was the standard Greek symbol to mark added text. . Other NT manuscripts also use obeloi to mark blocks of added text, including John .-. and Mark's longer endings.  Apparently, every manuscript with an obelos introducing Mark's longer ending notes that this ending is not 'in some of the copies'.
The name 'distigme-obelos' is ideal since it identifies the form of these symbols, a 'two dot-horizontal line', and their function, marking the location of blocks of added text. Their extension into the margin, on average, almost twice as far as the other twenty bars after distigmai, associates them with the adjacent distigme. The distigme-obelos symbols simply combine the Vaticanus standard distigme, marking the location of textual variants, with scribe B's favourite horizontal-bar-form obelos, specifying the variant is added text.
The virtually complete absence of high stops in the Vaticanus Gospels but their presence throughout the Vaticanus epistles and   indicates that the text of the Vaticanus Gospels is earlier than the text of the Vaticanus epistles and of   . This explains why the only case where a distigme-obelos marks added text that is actually in the text of Vaticanus is in its epistles. The Vaticanus Gospels preserve a text so early, it is not contaminated by any of the five additions its distigme-obelos symbols mark.
These symbols give evidence scribe B was aware of variants, copied exemplars faithfully, and preferred the earliest possible text. Scribe B was extraordinarily careful not to add to or take away text from Vaticanus' exemplars, not even adding high stops or obeloi at some places where original ink marginal notes identify LXX additions to the MT. Scribe B identifies  Cor .- as added text,  but faithfully preserved those verses from the epistles' exemplar, just as scribe B faithfully preserved obelised text in the Vaticanus prophets. It is precisely because of this honesty with the textual data that scribe B's text-critical judgements should be respected, not dismissed. All this supports Birdsall's judgment, 'Behind the quality of the New Testament text in this codex, there appears to be critical "know-how".'  Since manuscripts confirm the accuracy of every
