It is undeniable that the form of Seneca's Epistulae Morales we currently read is a work of literature, literature being here defined as a piece of work the author intended to publish. What Seneca claims in Ep. 21.3–5 is clear evidence of this:
exemplum Epicuri referam. cum Idomeneo scriberet et illum a uita speciosa ad fidelem stabilemque gloriam reuocaret, regiae tunc potentiae ministrum et magna tractantem, ‘si gloria’ inquit ‘tangeris, notiorem te epistulae meae facient quam omnia ista quae colis et propter quae coleris’. […] quod Epicurus amico suo potuit promittere, hoc tibi promitto, Lucili: habebo apud posteros gratiam, possum mecum duratura nomina educere.
However, this by no means implies that their nature is artificial or fictional, as many—perhaps most—Senecan scholars believe.Footnote 1 Furthermore, it is still worthwhile, once their ultimate literariness has been acknowledged, to investigate their genesis, for this may help us analyse the author's craft as well as go some way to revealing the historical circumstances behind their publication. Accordingly, I am going to portray the following scenario, according to which the Epistulae Morales should be considered real letters that an aged Seneca, reflecting daily on his experiences of human being, wrote to a friend.
QNat. 4a praef., originally a letter to Lucilius, sets up the beginning of a new atypical correspondence, in which Seneca tries to divert his friend Lucilius from his everyday concerns, at the same time directing him toward a more philosophical—that is, Stoic—way of life.Footnote 2 In order to do so and knowing that Lucilius is already an Epicurean sympathizer, at first Seneca tends to use Epicurean quotations (including some of Lucilius’ own verses), believing that this would be the easiest way to make his friend approach the new life. However, he manipulates these quotations in such a way as to convince Lucilius both that they can be considered Stoic as well, and that the Stoic doctrine is generally preferable, as it is more structured and complete. Ep. 34, explicitly recalling the intentions stated in QNat. 4a praef., draws up a provisional balance sheet of Lucilius’ significant improvement. Accordingly, the Epicurean presence in the following letters is much less considerable.
As implicitly emerges from this scenario, the first addressee whom Seneca had in mind must have been Lucilius, the sole addressee of both the Epistulae Morales and the Naturales Quaestiones, works which do not contain any explicit cross-references that urge readers of the one to become readers of the other as well. Of course, Seneca must have thought that, given the content of his letters to Lucilius, they—or most of themFootnote 3—might also be of use to a wider audience, perhaps after some changes or even taken one by one.
In support of my claim, I will first demonstrate the tight relationship between QNat. 4a praef. 20 and Ep. 34.2 (I). Further evidence will emerge from the comparison between QNat. 4a praef. 20 and other passages of the Epistulae Morales (II) and between QNat. 4a praef. as a whole and the Epistulae Morales (III). In a fourth section, I will then adduce several pointers to Lucilius’ Epicureanism (IV). Finally, by resorting to this sort of cross-reading of the Epistulae Morales with the Naturales Quaestiones—in the wake of Italo Lana and Gareth WilliamsFootnote 4—I shall also propose the following chronology for the Epistulae Morales and some books of the Naturales Quaestiones (V):
QNat. 4a before Ep. 34, or, more probably, before the first 34 letters (a.d. 61)
Ep. 18 December a.d. 61
Epp. 23 –67 spring a.d. 62
Epp. 68 –70 before 5 February 63
QNat. 6 after 5 February 63
Epp. 86–91 summer a.d. 64
Ep. 122 autumn a.d. 64
From the point of view of the Naturales Quaestiones then, this reasoning appears to bring new clues in favour of the order of the books fixed by the latest scholarship, that is to say, 3, 4a, 4b, 5, 6, 7, 1, 2.Footnote 5
I. QNAT. 4A PRAEF. 20 AND EP. 34.2: THE BEGINNING OF THE CORRESPONDENCE AND A FIRST BALANCE SHEET
That the preface to QNat. 4a is similar to any one of the Epistulae ad Lucilium has already been noticed by several scholars.Footnote 6 Delatte and Codoñer have also claimed that it could mark the beginning of the correspondence, but neither of them has furnished clear evidence of this, thus allowing other scholars to reject their thesis.Footnote 7
Yet, I think that a strong connection between QNat. 4a praef. 20 and at least one passage in the Epistulae Morales does exist. Evidence is brought by the comparison of these two passages:
hoc tibi, etsi diuidimur mari, praestare temptabo ut subinde te iniecta manu ad meliora perducam, et, ne solitudinem sentias, hinc tecum miscebo sermones. erimus una, qua parte optimi sumus. dabimus inuicem consilia non ex uultu audientis pendentia (QNat. 4a praef. 20).
adsero te mihi; meum opus es. ego cum uidissem indolem tuam, inieci manum, exhortatus sum, addidi stimulos nec lente ire passus sum sed subinde incitaui; et nunc idem facio, sed iam currentem hortor et inuicem hortantem (Ep. 34.2).
The nature of the content and the emphasized words in particular make the similarities appear clear, but they merit further examination.
First, in order to help Lucilius escape from everyday life, in QNat. 4a praef. 20 Seneca promises that he will not leave his friend to his own destiny, but will try to draw his attention, from time to time (subinde), to nobler themes, namely philosophical themes in their broadest sense. In Ep. 34.2, Seneca declares that he has kept his word: subinde incitaui. After all, if we consider the singular structure of QNat. 4a praef., the phrase ad meliora perducam is hardly restricted to the subject of the Naturales Quaestiones. Footnote 8 In contrast, when he resorts to words such as meliora, maiora, ampliora, Seneca generally refers to those activities typical of contemplative lifeFootnote 9—of which scientific investigation is obviously a considerable part, but not the only one—as opposed to those of active life, which inevitably not only characterized Lucilius’ everyday life but—to his great regret—also used to characterize Seneca's.Footnote 10
Second, the expression iniecta manu seems to be more emphatic and more meaningful if connected to inieci manum of Ep. 34.2. As we can see from several examples enumerated in TLL 7.1.1613.67–1614.15 and from at least one other occurrence in Seneca (Ben. 4.14.4), the ablative absolute iniecta manu may at times be regarded as a sort of crystallized phrase, whose link to the legal proceeding of the manus iniectio is not necessarily manifest or perceived.Footnote 11 Accordingly, it is not surprising that the passage of QNat. 4a praef. 20 is not listed by Armisen-Marchetti among those which designate ‘l'entrée en possession légitime d'un bien’ s.v. manum inicere, unlike that of Ep. 34.2, where this principle ‘s'applique […] au disciple, dont le maître “prend possession”’.Footnote 12 Yet, in both cases we should understand the hint to the legal proceeding of the manus iniectio, which is to say that iniecta manu also refers to the taking possession of Lucilius, although it represents a previous step to that of Ep. 34.2, a previous step when this manus iniectio has not yet happened.Footnote 13
Third, these two passages contain the only two occurrences in Seneca of the adverb inuicem with reference to Seneca himself and his interlocutor, Lucilius. However, if in QNat. 4a praef. 20 it is used in a context in which Seneca seems to propose the beginning of a double-sided correspondence, in Ep. 34.2 the situation is quite different, because it looks as if this correspondence is already going on.Footnote 14
In general, the contrasting use of tenses in QNat. 4a praef. 20 and Ep. 34.2 gives the impression that the latter represents a provisional balance sheet of the intentions stated in the former: the perfect tenses inieci, exhortatus sum, addidi, passus sum, incitaui and the present tenses adsero, es, facio, hortor replace futures like temptabo, miscebimus, erimus, dabimus.
II. QNAT. 4A PRAEF. 20 AND OTHER EPISTVLAE AD LVCILIVM
The tight relationship between QNat. 4a praef. 20 and the Epistulae Morales is also corroborated by other passages.
When in this paragraph of the Naturales Quaestiones Seneca says erimus una, qua parte optimi sumus, we note that the adverb una is used for the only time in the Naturales Quaestiones with reference to a ‘get together’ with friends, as often happens in the Epistulae Morales. Footnote 15 Obviously, this long-distance meeting can only be realized by means of a letter, whose aim is expressly to establish a colloquium with absentees, at least according to one of the most characteristic topoi of ancient epistolography (Latin, in particular).Footnote 16 There is more: judging from this passage, we can even state that a letter favours a conversation with the best part of an absent person, namely their inner part (pars interior).
The same idea is expressed in Ep. 55.9:
conuersari cum amicis absentibus licet, et quidem quotiens uelis, quamdiu uelis. magis hac uoluptate, quae maxima est, fruimur dum absumus; praesentia enim nos delicatos facit, et quia aliquando una loquimur, ambulamus, consedimus, cum diducti sumus nihil de iis quos modo uidimus cogitamus.Footnote 17
However, for the two friends to be una (‘together’), there must be a double-sided correspondence, the only way to effect a relationship between tutor (magister) and pupil (discipulus) that can benefit both.Footnote 18 It is evidently taken for granted that Seneca, when saying tecum miscebo sermones, alludes to the exchange of letters.Footnote 19 Nevertheless, what Seneca claims at the beginning of Ep. 38 and Ep. 75 not only is the confirmation of this meaning of sermo, but also allows further important reflection for the purpose of this paper.Footnote 20
merito exigis ut hoc inter nos epistularum commercium frequentemus. plurimum proficit sermo, quia minutatim inrepit animo: disputationes praeparatae et effusae audiente populo plus habent strepitus, minus familiaritatis. philosophia bonum consilium est: consilium nemo clare dat. (Ep. 38.1)
qualis sermo meus esset si una desideremus aut ambularemus, inlaboratus et facilis, tales esse epistulas meas uolo, quae nihil habent accersitum nec fictum. (Ep. 75.1)
While Seneca seems in the second quotation to be expressing the desire for his letters to have a style as inlaboratus et facilis as the style of sermo, in the first quotation ‘letters are the literary equivalent of conversation’.Footnote 21 The benefits deriving from this kind of communication are to be found in the continuation of Ep. 38 (38.2):
[sc. submissiora uerba] facilius intrant et haerent; nec enim multis opus est sed efficacibus. seminis modo spargenda sunt, quod quamuis sit exiguum, cum occupauit idoneum locum, uires suas explicat et ex minimo in maximos auctus diffunditur.
This last passage clarifies why Seneca wants to use letters as a communication medium: the choice of the epistolary correspondence is due not only to the long distance between the two friends but also to the benefits deriving from a more informal, immediate style.Footnote 22 This enables Seneca both to give his friend a few suggestions and teachings at a time, and to do it regularly, so as to achieve the optimum represented by daily spiritual exercises, on which a considerable part of ancient philosophical thinking (Stoic, in particular) is based.Footnote 23
III. OTHER PASSAGES OF QNAT. 4A PRAEF. AND THE EPISTVLAE MORALES
The connections between the Letters and QNat. 4a praef. are not limited to section 20 of the latter. Modern scholarship has already pointed out some of them, but either they merit further examination or should be reconsidered.Footnote 24
While reading the preface from its beginning, we immediately run into quemadmodum scribis (§ 1), whose importance Codoñer stresses, because this expression—she believes—together with tecum miscebo sermones of § 20 suggests the idea of an epistolary exchange.Footnote 25 Even so, this is the only occurrence of scribis in the Naturales Quaestiones against thirteen instances in the Epistulae Morales. Accordingly, Codoñer's reasoning can perhaps be pushed one step further, allowing the conclusion that in Seneca's Epistulae Morales there is the same opposition between inquis and scribis that can be found in Cicero's letters, where the first verb alludes to possible objections raised by his interlocutors, whereas the second refers to the content of letters actually received from them.Footnote 26 To this end, this fact could also be interpreted as a pointer to the non-fictional character of the Letters. If in the Epistulae Morales it could be seen as a device intended to give the impression of a real correspondence—like inuicem in Ep. 34.2—in the Naturales Quaestiones such use does not seem to make sense, since Seneca would not have any literary necessity of pretending an epistolary correspondence in this work.Footnote 27 Therefore, I do not see any reasons to doubt that it refers to a real letter written by Lucilius.
A few words later Seneca addresses Lucilius in this manner: scio quam sis ambitioni alienus, quam familiaris otio et litteris (§ 1). Gercke is probably the first to compare this phrase to the Briefkreis 19–22 and to declare that this comparison shows ‘eine auffällige Übereinstimmung in den Worten dagegen ein völliger Widerspruch im Inhalte’.Footnote 28 The contradiction to which the scholar alludes mainly consists in the fact that ‘in NQ 4, pref. I […] Lucilius is “ambitioni alienus”, but in Ep. 19–22 he has to be cured of ambition’.Footnote 29 Taking this assumption for granted, it would not be difficult to agree with Abel that ‘Man gewinnt den starken Eindruck, daβ die Briefe als Instrument sittlicher Selbstvervollkommnung für den Lucilius der Naturales quaestiones eigentlich überflüssig sind’, because it would really look as if QNat. 4a praef. displayed a situation subsequent to that of letters 19–22.Footnote 30 Nevertheless, I think that this interpretation does not hit the mark, because it does not sufficiently take the context into account (§ 1):
delectat te, quemadmodum scribis, Lucili uirorum optime, Sicilia et officium procurationis otiosae, delectabitque, si continere id intra fines suos uolueris nec efficere imperium quod est procuratio. facturum hoc te non dubito; scio quam sis ambitioni alienus, quam familiaris otio et litteris.
When Seneca says scio quam sis ambitioni alienus, quam familiaris otio et litteris, he is not (I propose) asserting a fact; rather, he is trying to persuade Lucilius that he must be ambitioni alienus and familiaris otio et litteris in order to continere id [sc. officium procurationis otiosae] intra fines suos […] nec efficere imperium quod est procuratio. Footnote 31 An expression such as scio quam somehow compels Lucilius not to disappoint his moral guide, not to reveal that he is not as uninterested in ambition (ambitioni alienus) as Seneca thinks he now is.Footnote 32 In this sense, facturum hoc te non dubito clarifies and confirms the projection into the future of the whole context. After all, if we accepted Gercke's explanation, we would find contradictions within the preface itself, with §§ 20–1 in particular. Both of these paragraphs reveal in fact that a great deal of work has yet to be done for Lucilius to remain unambitious. No doubt, this is implied in immo etiam a se recedendum of § 20, but becomes even more explicit in the paragraph that follows, when Seneca says (§ 21):
longe te ab ista prouincia abducam, ne forte magnam esse historiis fidem credas et placere tibi incipias quotiens cogitaueris: ‘hanc ego habeo sub meo iure prouinciam quae maximarum urbium exercitus et sustinuit et fregit, cum inter Carthaginem et Romam ingentis belli praemium iacuit; eqs.’
Were Lucilius really ambitioni alienus, all this section would seem rather superfluous.
Another significant item concerns the different aims of the Epistulae Morales and the Naturales Quaestiones. QNat. 4a praef. 3 begins thus: fac ergo, mi Lucili, quod facere consuesti. In addition to the fact that the exordium of Ep. 1 (ita fac, mi Lucili) cannot but occur to anyone who reads this passage, what is remarkable is that this is the only occurrence of fac in the Naturales Quaestiones: the use of an imperative—of fac, in particular—well fits the paraenetic aim, one of the cornerstones of Seneca's argumentation in the Epistulae Morales according to Cancik, but it would not fit the inquisitio causarum so well, a Senecan tag (Ep. 96.65) by which I. Hadot legitimately designates the Naturales Quaestiones. Footnote 33 By saying so, I by no means want to deny the moral as well as the scientific nature of this work.Footnote 34 Nevertheless, I want to stress that, according to the difference in aims outlined by Donini, the preface to QNat. 4a is inclined much more toward the inferior aim represented by a moral life—typical of most Epistulae Morales—than toward the higher goal of theoretical knowledge, which instead plays a central role in the Naturales Quaestiones. Footnote 35 After all, what Seneca claims immediately afterwards (a turba te quantum potes separa) seems to support this statement. Apart from another use of the imperative (separa), central is the presence of the topic of the separation from the crowd (turba, uulgus, populus), a recurring Epicurean theme in Seneca's work, in particular in the Epistulae Morales. Footnote 36 As Scarpat puts it: ‘La turba, quindi, rappresenta il polo opposto all'interiorità della persona; la turba è di ostacolo a quella vita di virtù che sola rende uomini; […] sono, insomma gli insipientes, gli stolti.’Footnote 37 As well as fugiendum ergo et in se recedendum est of § 20, it is quite evident that this expression first fits the paraenetic aim of the Epistulae Morales and only secondarily the scientific investigation of the Naturales Quaestiones.
IV. LUCILIUS AS EPICUREAN SYMPATHIZER
Having shown the connections between the Epistulae Morales and QNat. 4a praef., it is now time to turn to Lucilius’ initial attitude towards philosophy. Several scholars have already suggested that Lucilius was an Epicurean sympathizer.Footnote 38 In this section, I not only recall what in my view is the best evidence in favour of this theory, but also seek to make it stronger. Leaving aside more subjective and thus tenuous arguments,Footnote 39 proof of Lucius’ Epicureanism can be split into two parts: on the one hand we can infer an important clue from one passage of the Epistulae Morales, on the other from Lucilius’ own poetical fragments.
In Ep. 23.9, while addressing Lucilius, Seneca resorts to the expression Epicuri tui, thus explicitly admitting Lucilius’ Epicurean tendency.Footnote 40 Of course, given the extensive use of Epicurean citations in the first Epistulae Morales, Seneca too could be ironically defined as an Epicurean. However, there is no irony at all in Seneca's use of possessive adjectives or pronouns, let alone when it comes to discerning one philosophical tendency from another. On the contrary, a possessive adjective is what makes it always clear in the Epistulae Morales that Seneca is a Stoic. In fact, noster / nostri is exclusively used with reference to Stoic philosophers, with the exception of Virgil, whom every Roman could call noster, and Demetrius the Cynic, whom Seneca admired enough to consider him to be a real sage (sapiens).Footnote 41
Unfortunately, Lucilius’ poetical fragments are only three and are all to be found in Seneca's work, particularly in the Naturales Quaestiones and the Epistulae Morales. Footnote 42 However, one of these fragments may cast light on his philosophical attitude. In Ep. 24.21 Seneca, addressing Lucilius as usual, says:
haec cum descripsisses quo soles ore, semper quidem magnus, numquam tamen acrior quam ubi ueritati commodas uerba, dixisti, mors non una uenit, sed quae rapit ultima mors est.
Mazzoli compared this verse to Horace's mors ultima linea rerum est (Epist. 1.16.79), but this example does not fit in this context, because in the case of Lucilius ultima refers to mors, while in Horace ultima refers to linea. Footnote 43 Nevertheless, he was right in considering the expression ultima mors crucial. In Sat. 1.7.11–13 Horace writes: inter | Hectora Priamiden, animosum atque inter Achillem | ira fuit capitalis, ut ultima diuideret mors. Granted, it would be incautious to claim that ultima mors sounds typically Epicurean, but it is undeniable that this expression only met with Epicurean sympathizers’ approval, since it is found exclusively in Horace, who even called himself Epicuri de grege porcum. And if we do not restrict our research to ultima, the same concept is expressed by suprema mors, again in Horace, and extrema mors, used by another poet who in antiquity was usually regarded as an Epicurean sympathizer, Virgil.Footnote 44
These Lucilian verses quoted by Seneca are located in the first section of the Epistulae Morales, letters characterized by many citations taken from Epicurus. Wildberger has recently shown that in his earlier letters Seneca misrepresents and reinterprets some Epicurean ideas. In her view, this would prove that what she calls the ‘Letter Writer’ is not Seneca himself, because this sort of manipulation requires the kind of knowledge displayed by the ‘Letter Writer’ only in later letters.Footnote 45 However, another explanation seems by now to be possible: Seneca would have manipulated Epicurean quotations to convert Lucilius to Stoicism and would also have used Lucilius’ own verses to show him that (and how) they could go with Stoic doctrines.Footnote 46 This interpretation is more similar to Schottlaender's, who had already alluded to a sort of manipulation of Epicurean tenets made by Seneca, but he had also claimed that ‘Seneca will ihn [that is, Lucilius] zu dem besten Kern der von ihm selber anerkannten Lehre [that is, epicureischen Lehre] […] zurückführen, um ihn als hierdurch williger gewordenen Adepten in die umfassendere Wahrheit der stoischen Philosophie einzuweihen’.Footnote 47 After all, in the light of what was said above on the tight relationship between QNat. 4a praef. and the Epistulae Morales, Wildberger's theory of the Epistulae Morales as an epistolary Bildungsroman would seem difficult to accept, because it would somehow imply that the first chapter of this novel, that is to say, QNat. 4a praef., should be located in another work. On the contrary, if Lucilius was the real and first addressee of the letters, he could have received and read both the future QNat. 4a praef. and the other future Epistulae Morales.
V. CHRONOLOGY
In QNat. 6.1.1 we read:
Pompeios, celebrem Campaniae urbem, in quam ab altera parte Surrentinum Stabianumque litus, ab altera Herculanense conueniunt et mare ex aperto reductum amoeno sinu cingunt, consedisse terrae motu, uexatis quaecumque adiacebant regionibus, Lucili uirorum optime, audiuimus, eqs.
This very objective description, which precisely explains the geographical location of the city of Pompeii, is perfect for a general audience, which does not necessarily know where this city is, but it would be completely superfluous for Lucilius. In fact, as emerges from the Epistulae Morales, he knows Pompeii perfectly well, for it is probably his hometown: ecce Campania et maxime Neapolis ac Pompeiorum tuorum conspectus incredibile est quam recens desiderium tui fecerint: totus mihi in oculis es (Ep. 49.1) and post longum interuallum Pompeios tuos uidi (Ep. 70.1).Footnote 48 The preface to QNat. 4a and the very intimate relationship between Seneca and Lucilius, which emerges there, stresses even more the difference between what was originally thought to be read by Lucilius (the Epistulae Morales, including QNat. 4a praef.) and what was directly intended for a wider audience (QNat. 6).
Most of all, the comparison between the beginning of QNat. 6 and Epp. 49.1 and 70.1 is important for the chronology of the Epistulae Morales and the Naturales Quaestiones; therefore, before addressing the well-known issue concerning the dating of the Pompeian earthquake of QNat. 6, I should like to speculate further about it.
The different attitude toward the addressee in this book of the Naturales Quaestiones as opposed to the addressee of the Epistulae Morales is shown not only by the objectivity of the description of Pompeii but also by Seneca's dispassion in speaking about an earthquake which has destroyed his friend's city. Bearing in mind the tragic destiny of Pompeii, is it plausible that the earthquake had already taken place when Seneca wrote to Lucilius in both Letter 49 and Letter 70 that the view of this Campanian city reminded him of the happy moments spent together by the two friends? I believe that the absence of even the slightest hint of this catastrophe in these letters proves that they had been written before the Pompeian earthquake and, consequently, before QNat. 6.Footnote 49 This would also mean, since in QNat. 6.1.2 we read that Nonis Februariis hic fuit motus Regulo et Verginio consulibus, that they were written before 5 February a.d. 63.Footnote 50 Unfortunately, this explicit date—the only one in the Naturales Quaestiones—has raised several doubts for modern scholars, although—I agree with Wallace-Hadrill—this issue ‘scarcely merits the length of its bibliography’.Footnote 51 This uexatissima quaestio is due to a comparison with a passage of Tacitus (Ann. 15.22) in which the earthquake that devastated Pompeii and the Campanian region dates to a.d. 62. Without recalling the different opinions of the nineteenth- and twentieth-century scholarship with regard to it, I should like to focus mainly on a textual aspect.Footnote 52 Those who are inclined to think that Regulo et Verginio consulibus is a gloss run up against a serious methodological problem: a possible textual error, in order to be proved that it actually is an error, should show the reason of its existence.Footnote 53 In this case, what could justify the presence of this gloss? We would be forced to postulate the existence of a scribe who simultaneously was brilliant enough to know that he could find the consular date of this earthquake in Tacitus’ Annales and so careless that he mixed up the consuls and the years (or could he resort to another source?).Footnote 54 Granted, supporters of the gloss-theory may invoke the different position of the phrase Regulo et Verginio consulibus in the two branches of the textual tradition of the Naturales Quaestiones as well as the addition of the cognomen Rufo in Z, which alone represents one of the two branches.Footnote 55 Yet, Hine himself admits that this change in position can also be explained in other ways, for example as a case of reinsertion in different places of original Senecan words which had been omitted by parablepsy.Footnote 56 But it is also the case that names of consuls and consular dates are easily subjected to interventions and corruptions, without this making glosses of them. In trying to counter the hypothesis that we face a case of parablepsy (which he himself puts forward), Hine involuntarily gives another very reasonable explanation for the word order in Z. He writes: ‘the word order given by Z is more natural, since it puts the consular date adjacent to the calendar date.’Footnote 57 This is true, but any scribe who was a little versed in Latin, having Hine's same feeling, could have decided to restore the more natural order. In other words, the word order of Z can easily be explained as a case of hypercorrection, that is, as a voluntary intervention of the scribe. As for the addition Rufo, compare, for example, Sall. Iug. 27: consules declarati P. Scipio Nasica, L. Bestia Calpurnius; Calpurnio Numidia, Scipioni Italia obuenit. Reynolds's OCT apparatus criticus immediately shows how praenomina, nomina and cognomina can equally be present or absent in manuscripts: L. bestia calpurnius C2HF : L. bestia C. B : L. bestia calpurnius L. bestiae A1C1 : L. bestia calpurnius L. bestia C. A2 : L. calpurnius bestia ND2 : L. bestia PD1. In the light of this, the standard criteria of textual criticism alone do not give enough evidence to invoke the presence of a gloss, and, were it not for Tacitus’ testimony, no one would question Seneca's reliability. The only possibility left is therefore to decide who merits more credit: Tacitus or Seneca? Personally, I would find absurd to ascribe such a confusion to a person who is talking about a contemporary event.
If there was a confusion or imprecision on the part of Seneca, it concerns the expression anno priore that we read in QNat. 6.1.13 with regard to the Achaean and Macedonian earthquake and its relationship with the comet of a.d. 60.Footnote 58 If this earthquake took place one year before the Campanian earthquake and immediately after the comet of a.d. 60, it is much more convenient to date the destruction of Pompeii to early a.d. 62. Despite the objections raised by Hine, if we did not approve of Wallace-Hadrill's reasoning (anno priore can also refer to the beginning of a.d. 62) or we did not think of Seneca's vagueness in making calculations, we would be compelled to more drastic interventions in the chronology of both the Naturales Quaestiones and the Epistulae Morales. Footnote 59 As an alternative, we should think that the letters, as we read them, are not in chronological order, but no one until now has called this fact into question thanks to the (albeit sporadic) chronological references that we find among them and the development of the figures of Lucilius and Seneca that we can perceive throughout the course of the correspondence.Footnote 60
On the contrary, if we accept for the books of the Naturales Quaestiones the order which is nowadays considered to be the most probable, if we consider genuine and correct the ablative absolute Regulo et Verginio consulibus of the manuscripts, and if we combine this clue with the comparisons between Ep. 34.2 and QNat. 4a praef. 20, and between Ep. 49.1–70.1 and QNat. 6.1.1–2, and with the only absolute date of the Epistulae Morales, namely the date of the destruction of Lugdunum, which plays a central role in Ep. 91 and dates to late summer or early autumn of a.d. 64, then we will obtain this cross-chronology:Footnote 61
QNat. 4a before Ep. 34, or, more probably, before the first 34 letters
Ep. 18 December
Ep. 23 spring
Ep. 49 before 5 February 63
Ep. 67 late spring
Ep. 70 before 5 February 63
QNat. 6 after 5 February 63
Ep. 86 late June
Ep. 91 late summer / early autumn 64
Ep. 122 autumn
According to these data, we cannot but infringe a sort of taboo, the terminus post quem for the Epistulae Morales represented by the spring of a.d. 62, when, according to Tacitus (Ann. 14.52–6), Seneca, so to speak, retreated from political life. Nevertheless, as Hine puts it:
we should not be too fixated on Tacitus’ account of the interview between Seneca and Nero in a.d. 62 as a turning point, for the change in Seneca's influence and standing in the court, and in the balance he struck between court duties and philosophy, may have been more gradual.Footnote 62
After all, even in a passage usually considered decisive for dating the Epistulae Morales to this time, we do not read a clear hint of political life but rather of private business: secessi non tantum ab hominibus sed a rebus, et in primis a meis rebus: posterorum negotium ago (Ep. 8.2).
Based on these assumptions, we may date QNat. 4a to an undetermined period of a.d. 61 (in any case before December), Ep. 18 to December a.d. 61, Epp. 23–67 to the spring of a.d. 62, Epp. 68–70 to a period previous to 5 February a.d. 63 and QNat. 6—as already said—to a period subsequent to 5 February a.d. 63.Footnote 63 Assuming that Ep. 86 dates to the same summer of Ep. 91 (that is to say, the summer of a.d. 64), at most fifteen of the letters we have were written between 5 February a.d. 63 and the summer of a.d. 64.Footnote 64 If the dating of the earlier letters to some time of a.d. 61 even crosses the boundaries of the so-called long chronology (a.d. 62–4), to date Epp. 23 and 67 to the same spring is rather typical of the supporters of the short chronology (a.d. 63–4). Yet, the established opposition between long and short chronology, as well as resting on tenuous arguments, either takes for granted or ignores too many variables.Footnote 65 Some clarifications are in order. First, what I claim here is that the Epistulae ad Lucilium that we read are true letters which Seneca wrote to his friend between a.d. 61 and 64: nothing more and nothing less. Second, as my previous discussion of Ep. 121.18 should show, presumably Seneca did not include in the collection he decided to publish all the letters he wrote to Lucilius, and even taken alone this fact could give reason for the apparent unevenness in the rate of writing.Footnote 66 Third, even admitting that there are no missing letters within Books 1–20, we cannot know whether Seneca actually sent all the letters, whether he always waited for Lucilius’ reply before writing a new letter, whether the two met in person when there is no epistolary correspondence, and so on. Regardless of these speculations, the dating I propose—I hope—only rests on what we can read in the Epistulae Morales and in the Naturales Quaestiones.
