โI sing of arms and the man,โ said thundโring Virgil; and all the world knows that he said it. Or do they? How do you know what Virgil said? How do I know? How does anybody know? Take in hand a modern edition of Virgilโs Aeneid โ the โOxford Classical Textโ of Sir Roger Mynors, for example โ and there you will indeed find printed the words Arma virumque cano, which do indeed mean โI sing of arms and the manโ. But on whose authority do the people of the Oxford Classical Text series assert these words to be Virgilโs? And on whose authority do the people on whose authority the people of the Oxford Classical Text series assert these words to be Virgilโs themselves assert these words to be Virgilโs? And on whose authority do the people on whose authority the people – etc., etc., etc. This is less a silly question than it is a silly way of putting a serious question, a question which many have devoted their lives to answering, and which even today continues to perplex us:
How do we know what the authors of antiquity actually wrote?
Why such a question needs asking may not be immediately obvious to you; to me it was less obvious than it was obnubilous. But there is a reason, and it is not a happy reason. Out of all the great works of Classical literature ever written, not one survives in the form of an authorโs original manuscript. Papyrus was then the writerโs medium of choice, and, not being a very durable substance, in the damp climate of Europe it tended to rapid disintegration. What survives are mere copies of these originals, and copies of those copies, and copies also of those copies, and further copies still โ all connected in one continuous chain, unbroken from the early days of antiquity and extending up to the first light of Renaissance humanism, until the invention of printing eventually took over.[1]

Now, as anyone who makes a business of copying things by hand should know, the process is rather a delicate one, and exceedingly prone to error. Imagine an entire book-trade operating along the same lines as a game of โbroken telephoneโ.[2] Copyists make mistakes, and copyists copy mistakes. Set several thousands to work copying out all of Classical literature, and you eventually have a bit of a problem on your hands. Even in ancient times the phenomenon of the spelling mistake was a source of confusion and high displeasure. Hear the first-century poet Martial, who has a thing or two to say about it:
si qua videbuntur chartis tibi, lector, in istis
sive obscura nimis sive Latina parum,
non meus est error: nocuit librarius illis,
dum properat versus adnumerare tibi.[3]
โIf anything in these pages seems a bit obscure to you, reader, or a little un-Latin, itโs not my fault: a scribe did the hurt in his hurry to count them out for you.โ
For a scribe at work in a medieval scriptorium (writing room) the situation was still more dire. Such a man had to contend not only with the often illegible handwriting of his predecessors, but also the inherent difficulties of the language and literature which it was his charge to copy. Latin was no-oneโs native tongue in the time of Charlemagne;[4] and those little few who did know the language had not the advantages of dictionaries, standard grammars, and the Logeion app for iOS and Android. Under such conditions as these, errors of transcription were inevitable; and it should therefore be no surprise to you, nor any great reproach to the scribes, if they be discovered muddling the ends of verbs, skipping their eye over paragraphs, or mistaking nouns for their doppelgangers โ writing, e.g., deus (โgodโ) for decus (โgloryโ), homo (โmanโ) for humo (โto the groundโ), or angues (โsnakesโ) for aures (โearsโ).[5]
Scribal errors were one thing that did the hurt; physical damage was another. Spills of water could make a line illegible; a piece of straw could be mistaken for a wayward colon; pages could fall out, margins could be set fire to, and whole codices could be scrubbed of their contents and recycled into more useful products. One and half millennia of such rough handling was enough to make quite a difference to any text, and many of Greeceโs and Romeโs most brilliant works of literature suffered grievously by it. Of the surviving greats, Catullus and Propertius come to mind as having been particularly mangled, but many โlesser authorsโ were treated far worse โ lesser, perhaps, only because the circumstances of their survival were less felicitous.

Eventually, from all this copying, miscopying, cutting, splicing and pasting there emerged a vast multitude of Classical manuscripts dating from every epoch. Some authors appear in only one or two of these MSS (as the standard abbreviation goes); others can lay claim to hundreds. Like witnesses to a crime (the crime of gradually debasing the words of a great author, I suppose), each manuscript has its own version of events. One may give Virgilโs words as Arma virumque, โarms and the manโ; another Arva virumque, โfields and the manโ; a third Aram vinumque, โwine and the altarโ. Here enters the editor. Their task is to select out of all these different โreadingsโ (often called variae lectiones in Latin) those which, in their judgment, are most probably the words of the author. This is largely a game of informed guesswork โ what you might call a โscience conversant with literatureโ.[6]
It is also in great measure an art, especially that province of criticism which deals in the reconstruction of โcorruptโ text โ text which the manuscripts furnish in a state so utterly nonsensical that its author could not possibly have written it so. A good example of โconjectural emendationโ โ that is, restoration by informed guessworkโ โ may be taken from the first book of Maniliusโ Astronomicon, a long poem on Roman astrology. One important manuscript presents verses 423โ4 of Book 1 in the form โ esurcioneโ Iuppiter ipse | quod poterat non posse timens, โJupiter himself โ then gibberish โ fearing he cannot (do) what he once could.โ[7] esurcione is no Latin word Iโve heard of, nor one that the formidable critic A.E. Housman had ever heard of either; in 1903 he conjectured, quite brilliantly, that esurcione was a debasement of the words eguit Iove, and that the whole phrase really meant โJuppiter stood in need of himself, fearing that he could not do what he once was capable of.โ All later editors accept this correction into their texts, taking it for a moral certainty that Manilius once wrote what Housmanโs brain long after divined.
Few will contest editorsโ judgments in this matter. But what happens when their judgment is not so assuredly sound? What if they get it wrong? Editors have an answer to this question, and they give it in the form of the apparatus criticus, or what you might call in English a โcritical apparatusโ. Literally, the apparatus criticus is an โarsenal of judgmentโ; it is also a place for editors to record all the relevant evidence on which their text of an author is founded: i.e., the testimony of the manuscripts whose evidence matters, and the later corrections of critics. Editors give this information as a tool for the readerโs use, that he or she may consider editorial decisions in the full light of the evidence, and consult his or her own judgment in places where the text does not appear to be sound.

The apparatus is eminently a tool for the people (not the editor), but it is not made to seem so. Different publishers have different policies regarding how fat or thin their so-called โapp. critt.โ should be, and naturally editors have their own opinions. The original tagline of the Oxford Classical Text series โ โbrevique adnotatione critica instruxit,โ โand furnished with a short critical commentaryโ โ promised brevity where other publishers proclaimed exhaustiveness. Compare how the latest editor of Homerโs Iliad for the German-based Teubner series described his handling of the text: โrecensuit, testimonia congessit Martin L. Westโ, literally โedit [and] pile up with evidence did Martin L. West.โ A quick squiz at the apparatuses of the OCT and of Westโs Teubner will be enough to see the difference:

West (2006) on Iliad 1.1โ5. 
Munro and Allen (1902) on the same.
The apparatus of the Iliad is a special case, not least because it is the oldest literary text we have in Ancient Greek; others are much simpler. Let us take for our example the manuscript tradition and apparatus criticus of Maniliusโ Astronomicon, famously edited by Housman in five instalments (1903โ30). The complete text of this poem is established upon the testimony of three manuscripts which editors consider to be of โindependent authorityโ, which is to say they are the only three manuscripts we have that are not known to have been directly or indirectly copied from another manuscript still in existence. Each therefore matters to the editor, as each stands at the end of a long chain going back to the authorโs own text.[8] For the sake of time and space, editors have collectively chosen to denote these manuscripts by โsiglaโ, individual letters in Greek or Roman script. For the Astronomicon these sigla are L, G, and M, standing respectively for the Codex Lipsiensis (โmanuscript from Leipzigโ), Codex Gemblacensis (โMS from Gemblouxโ) and Codex Matritensis (โMS from Madridโ).
Here things begin to get a tad metaphorical. Editors like to talk about manuscripts as if they partook of the nature of families. (Technical discussions about manuscripts thus have a peculiar tendency to sound rather like a family drama.) So, a manuscript like L may be said to be a โparentโ (i.e., a manuscript from which others have been copied), as well as a โsiblingโ (i.e., a manuscript related to another derived from the same โparentโ as L). As it happens, L really does have a sibling, and it is G: both L and G are thought to have derived from a common ancestor no longer in existence, and which editors denominate ฮฑ. (Greek letters are often used for โconjecturalโ MSS, or MSS regrettably no longer in existence.) M is thought to be the sibling of ฮฑ, and thus the โuncleโ, so to speak, of L and G. You can draw a family tree (or stemma) of this arrangement like so:

The manuscript O (sometimes also ฯ or ฮฉ) is the letter typically given to the archetype, or what may be defined as โthe latest common ancestor of the known manuscriptsโ.[9] The point of reconstructing these various affiliations is not only to produce a pretty diagram, but also to help the editor adjudicate between variants. Imagine, for example, that in the sentence currum ascendi (โI hopped into my chariotโ) M gave the first word as currum, but GL instead gave crinem (โhairโ). The agreement of GL enables you to infer (with practical certainty) that their parent ฮฑ also had crinem: it is vanishingly unlikely that the scribes of L and of G both made the same mistake, at the same point in the text, of writing crinem for currum.
Yet, since M and ฮฑ are siblings, one cannot say for a surety whether their (lost) parent O had currum or crinem. All you can say is that either M or ฮฑ inherited the true reading, and the other made a mistake. The only way for the critic to decide what stood in O, and to reconstruct what we trust Manilius wrote, is simply by considering the sense produced by each alternative: as โgetting into a chariotโ makes markedly more sense than โgetting into a lock of hairโ, very probably the poet wrote currum, not crinem.
With this method in mind, let us turn to consider a real-world example: the beginning of the third book of the Astronomicon, lines 1โ4. (The text printed below is Housmanโs.)
in nova surgentem maioraque viribus ausum
nec per inaccessos metuentem vadere saltus
ducite, Pierides. vestros extendere fines
conor et ignotos in carmina ducere census.
2 vadere G : invadere LM | saltus GL2: saltos M | 4 ignotos Housman : dignos LM : indignos G : indictos Gron.| carmina M : carmine GL | census Unger : cantus O
โAs I rise to fresh heights and venture a task beyond my strength, fearlessly entering untrodden glades, O Muses, be my guides. To widen your domains I strive, and to bring new treasure into song.โ[10]
Unpacking the arguments of these curious footnotes (what weโve been calling the apparatus criticus) is simpler than it may at first appear. Each entry is separated from the others by one or two vertical strokes |, and each corresponds to a specific word or collocation of words in the text. You can tell which line an entry refers to by the number at the front of it. Within each entry are contained the variant readings of manuscripts and suggestions of critics, all separated by colons, and ordered from left to right according to how probable the editor considers them. Thus the entry โ2 vadere G : invadere LMโ translates to โin line 2, the manuscript which I call G gives the reading vadere, and I as the editor consider this word as more probably what Manilius wrote than the reading given by manuscripts L and M, invadereโ. Hence in Housmanโs text, printed in the main body of the page, vadere stands, while invadere appears only in the apparatus.

Manuscripts are usually distinguished by bold letters; italics are reserved for the conjectures of recognised human beings. Thus โcensus Unger : cantus Oโ means โthe archetype O had cantus (โchantsโ), but personally I prefer Mr Ungerโs correction, census (โtreasuresโ), for it gives better sense to me.โ As paper is a precious resource, and as the editors of Classical texts are acutely conscious of the ecological ills that accrue to wastefulness, not everyone mentioned in an apparatus is permitted to have their names recorded in full. The price of fame in the world of text-editing is to have oneโs surname clipped by a dot in the app. crit.: thus โGronov.โ in line 4 stands for โGronoviusโ, i.e., Johann Friedrich Gronovius. Among other common abbreviations are Heins. for one of two different people (Daniel and his even more ingenious son Nicolaas) named Heinsius, Bent(l). for Richard Bentley, and Lach. for Karl Lachmann.
Now here may be a good place to test an editorโs judgment against our own common sense. The first question we meet with in this apparatus is that of whether to print vadere (โto proceedโ) or invadere (โto enter uponโ) in line 2. That is not an easy problem to solve, and Housmanโs judgment on this point may perhaps be faulted. For one, โto proceed through inaccessible grovesโ sounds rather weaker than โto venture uponโ the same. invadere is assuredly the more striking word, and the more suitable to this proemโs vaunting tone. Housmanโs choice of vadere may also be mistaken in one other important respect: it ignores what we know of Maniliusโ stemma, and ignores what we know of how to use it. Consider the readings again in this format:

This is not a simple case of โM has invadere, ฮฑ has vadere; pick one or other at your pleasure.โ M certainly does have invadere; whether ฮฑ had it is in doubt, and therefore whether O had it is much less assured than if both branches were in equal disagreement. Consider it this way: if O did have vadere, then two manuscripts (ML) must have each independently innovated the reading invadere by mistake.But if O originally had invadere, then only one manuscript (G) need have produced an innovation (by writing vadere). As the second of these two hypotheses involves the fewer assumptions, a prudent editor would say it is the more probable of the two, and thus the better explanation to adopt โ you know, Occamโs Razor and all that.[11] To such an editor Housmanโs preference for vadere may seem perplexing. Sure, the fact that the archetype O had invadere is no guarantee that Manilius actually wrote it (for many MSS must have passed between Maniliusโ original and the archetype), but given that the manuscripts are our first and only evidence in this matter, why distrust them here?
Housman felt he had a reason to distrust them. To his knowledge, and to the knowledge of the writers of our dictionaries, the verb invado is not anywhere found in employment with per (โthroughโ) when it has the sense of โto venture uponโ, and the standard usage of Latin verbs of motion with the prefix in- is not such as to suggest that invado could ever be so employed. Or is it? Housman himself admitted the example of intravit levior per corpora somnus, โlighter sleep entered through the bodyโ, a verse from the pseudo-Virgilian Culex (v. 206). And whoโs to say that Manilius could not have innovated this particular use by analogy, or that further examples of invado + per could not have existed in other Classical texts now lost to sight?

The conduct of Housmanโs mental operations in this matter โ that is, adopting into his text what I believe to be the error of a scribe instead of the reading of the archetype โ is an instructive example of how ideology may operate even in the arid territory of textual criticism. You might say that his approach here is that of a โstandardiserโ, of one who would prefer his Classical authors to conform always to accepted rules of grammar, not to abandon them on a whim. The only reason why invadere + per does not appear in the Oxford Latin Dictionary (1968โ82), or in the monolithic Thesaurus Linguae Latinae (1900โ?), is because Housman chose not to print it here. Had someone with a more liberal view of Latin poetic usage edited Manilius, perhaps these books would contain such an entry. That is not to say that editing is an affair of mere taste or literary preference; canons of grammar and metre have a central place in criticism along with stemmata. But dogma and doctrine partake of criticism as well: editors have their styles as well as authors.
So, is all that now reason enough to read Virgil with an apparatus? If you have the time and inclination, why not? It gives you power to hold editors to account for their decisions, and may even afford you the opportunity, like it did Housman, to restore the words of an author yourself.
To read a Classical text without an apparatus has been justly compared to the experience of sitting in the back of a car while another controls the wheel. In the fullness of time, come the development of the self-driving car, this simile may eventually lose its force; but the apparatus will certainly not have lost its relevance to those who are fascinated about what ancient writers actually wrote.
