Social Media, Historical Memory, Political Change and Oysters

The Walrus and the Carpenter
http://i.imgur.com/eEzb9uO.jpg
A few weeks ago, I was eating oysters (that was a first for me), trying to explain to my interlocutor what it is that I do. Figuring that a detailed exposé of diocesan administration in Late Antiquity would…well, be boring, I chose to focus on a different topic, historical memory. As an example, I asked why, out of the millions of micro-events that happen to “you” on a daily basis, do “you” choose to construct your personal narratives along certain nodal points. For instance, my father came to every soccer game of mine until college, why do I remember the one he missed? That game did not matter at all. 


Moving on, today I got a notification from Facebook: on this day this happened to you in the past (well since 2006). A flurry of inconsequential events: I wrote a review of the Second Law by Muse (I forgot I did that, I love that album), I had a message from a dear friend about her life in Paris (she lives in Qatar now) and how well that was going, and I apparently felt the need to share that I came back from visiting an ex-girlfriend in Rochester with a cold… and so on. Nothing that will fundamentally alter my life, or my personal narrative, and yet.

Facebook, with its “today in your life” feature, can probably remind us of some important aspects of our individual lives. A friend, for instance, reposted a picture of a goat cheese from 2005. I have no idea what that means, but it obviously struck a chord. I will not suggest that Facebook has the power to drastically alter our own personal narrative, but it might create nodes around which memory can coalesce. Perhaps that goat cheese was so good that he eventually became the cheese aficionado I know he is today: a memory of cheese-loving life coalesces around that picture. He may not have remembered this until today. Or it’s just something ridiculous

This is all good for people, but what about societies and nations? Nations are constructed around historical narratives. This is not new. We used to say, “history is written by winners.” Now in historical lingo, we speak of historical memory, which is essentially the same, except that crafting history occurs at the social level. To say, “history is written by winners,” is to occlude the myriads of regional, local and familial histories that exist and are an integral part of History. The record books of Aurelius Isidorus (I know right?) are now an important source for the historical narrative of late-antique Egypt. Consider the trove of documents found in the Cairo Geniza that shed light on medieval Jewish life (including a poet whose existence had been posited but not proven until the
Solomon Schechter Studying the Fragments of the Cairo Geniza
http://blog.longreads.com/2015/02/25/the-holy-junk-heap/
1970s). In other words, the narratives of the fall of Rome, the Middle Ages, etc… are not only written by the state apparatus, but also by some Roman city official in the south-east corner of the Empire (Ok, that’s not fair, Egypt was tremendously important, but still). So winners write the history of nations, but there is a multitude of microhistories that provide a fundamentally different history: different focus, different scope, different sources, different time-frame (not to mention different reckoning of time).

Perhaps it is time for a bit of definition. I am not interested in memory in the psychological sense. Rather, I would like to focus on social memory—its parallels with psychological memory are perhaps obvious, but this is not the focus on this post. Pierre Nora speaks of lieux de mémoire (sites of memory) as the places “where memory crystallizes and secretes itself.” Nora sees these sites of memory as an inherently modern problem; a set of artificial loci meant to deliberately preserve what history seeks to destroy. These loci are, for instance, archives, commemorations, celebrations etc… (and trust me historians do attack these lieux de mémoire). These loci are static and derive their significance from systematic repetition of specific acts through generations. Les lieux de mémoires, therefore, stand in sharp distinction from the processes by which social memory is sometimes, but mostly often, created in “so-called archaic or primitive societies.” Let us not criticize Nora’s adherence to the “myth of the good savage,” since he is mostly correct despite the problematic verbiage.

The fireworks to commemorate Bastille Day or Independence Day are part of a unitary remembrance that crosses many social and ethnic boundaries. Both days mark an arbitrary starting point for the nation, and both days are equally artificial. France underwent numerous constitutional changes between 1789 and 1804, not to mention between 1789 and 1958. July 4, 1776 makes some more sense, although the state envisioned in the Articles of Confederation is vastly different from the one we have now. Remembrance has become institutionalized at the level of the nation.

So why Facebook, and what role does social media play in the shaping of historical memory. To answer this is moot presently. I have literally no idea how much of an influence Facebook will have on the perception of the turn of the millennium by future generations. It will take many more years before we can begin to have an idea. But what role COULD social media have?
Do I Really Need to Caption This?
http://growingsocialmedia.com/wp-content/uploads/2014/11/download.jpg

Let’s take my Muse review as an example. I could (admittedly with great difficulty) deny that I ever loved Muse. Facebook could provide a counter-example. OR, I could argue that I was always a Muse fan, and we can have an example. At the level of the individual, we can use Facebook to confirm or deny personal narratives, by bringing up obscure moments in time. What can we do at the level of collective memories?

Facebook is a network, a series of mini-interacting social groups. In my case, my grad student “society” which spans over many states, and many generations (some were grad students), and merges with family, friends of various eras of life etc… It is a place where the memories of one social group are shared with another, while the other groups can only glimpse at the meaning ascribed by the memory. When we repost a memory, we partake in the process of memory making for a specific group. The memory more historical, more static and more permanent than the one we remember at the kitchen table through speech. And we share it with all these other networks: the group, therefore, loses the ownership of the memory.

In the context of esoteric memories—that is memories, the meanings of which are available only to the group—the weight of Facebook can be minimal. But social memories, or rather, traumas covered in the press, can provide a different story. The posting and reposting of national or global events reaches new audiences. The destruction of Palmyra, the Syrian refugee crisis, election problems and especially the mass shootings have been posted and reposted to the point that the issue of gun control was at the forefront of the democratic debate on October 13, 2015. Anderson Cooper stated that gun control had been one of the most trending topics on social media. Could these become new events become lieux de mémoire?

I will not speculate as to what Facebook can do. But if Facebook can become the repository of the sites of memory of simple groups like college alumni, it’d be fun to imagine around what sort of events, as a society, we could choose to build our identity. What if next year, on October 1, 2015, we all reposted a memory about Roseburg?


I discussed here the problems of building memory, and that memory becomes less dynamic. The issue of Facebook, and more broadly Big Data for historians and the historical method will be discussed later.

Looting and Destruction in Syria and Iraq (and ASOR)

On September 29, Trevor Noah had a segment on the Daily Show about the theft and resale of important cultural artifacts stolen in Syria and Iraq. The sale of these artifacts brings in roughly $100M/yr to ISIL to run its operations. This corroborates a figure given by Michael D. Danti in a talk at PennSt on September 16, 2015.

The cultural destruction of Syria and Iraq is not limited to the pre-Islamic past, although that is all CNN et al. are willing to report. Professor Danti mentioned that the destruction of pre-Islamic buildings or statues is strategic: it is a message addressed to the west. This destruction represents only a small portion of the actual destruction inflicted by ISIL on world heritage sites. Mosques or any Islamic site too closely associated with forms of Islam deemed sacrilegious are systematically leveled. For instance, on August 10, ISIL reported the destruction of Sufi shrines and graves in Fallujah.

Two points.
1) The destruction of sites in Iraq and Syria is not limited to western heritage sites. In fact it does not represent much in comparison to other sites.
2) The sale of antiquities on the Black Market is a very real source of income for this terror group.

The Fall of Rome

-->

from nytimes.com
Rome’s fall was a cataclysm. How great? Well, it is still used in modern political discourse to justify political positions. Most recently, by Ben Carson attributed the fall of Rome to matters like homosexuality, sports and political correctness. Dr. Carson (the other kind of doctor) is using Rome to make points about his political stance and gain votes. To demonstrate how wrong he is would be … well… obvious and pointless. But it shows the enduring power of Rome as a world empire. So let’s talk about what happened.

People didn’t wake up one day and Rome was gone. That is not to say that individuals did not understand that their way of life was crumbling. In 382, the emperor Gratian removed the altar of victory from the senate house. This event prompted the senate, in 384, to send one of its most prominent member Q. Aurelius Symmachus to the court at Milan to plead with the emperor to restore the altar. In his plea, Symmachus conjures up the spirit of Rome, the goddess Roma, to request the return of the old order. Roma wishes to “use the ancestral ceremonies,” to “live after [her] own fashion,” because “this worship subdued the world to my laws.” While speaking of the sack of Rome by Alaric, Augustine spoke of “this universal catastrophe” (City of God I.9). And later in the fifth century, Sidonius Apollinaris, the erstwhile Urban Prefect of Rome, saw, as Bishop of Clermont-Ferrand, the Visigoths besiege his city.

Roman Dacia

So what happened and why? First, a bit of chronology. The political structures of imperial Rome did not disappear all at once, at the same time, or for the same reasons. The trans-Danubian province of Dacia disappeared between 270 and 275. Britannia was abandoned in 407. There is no administrator for the diocese of Spain (the vicarius) after 401, and, for the diocese of Africa, after 413. Northern Gaul perhaps saw the disappearance of its civil adminitration after Constantius II defeated Magnentius. Certain areas of Gaul developed some form of “self-rule” (the Bagaudae) in the wake of imperial absence, especially in the Loire and certain areas of Brittany. Asterix, it seems, was back by the middle of the fourth century. In the eastern empire, the state of affair endured unimpeded until the reforms of Justinian in the sixth century.

If we start the premise that the fall of Rome was a rather checkered process, it becomes increasingly difficult to find a single cause for its decline. I mean surely sports were prevalent in the east and in the west, so why did the east endure another century or two of imperial rule?

There is no simple answer to this question. Historians have agreed and disagreed. The examples given above are epiphenomena: A.H.M Jones, in his magisterial study The Later Roman Empire, does not mention that Gratian removed the altar of victory. Recently, advances in paleoclimates have shown periods of flooding in certain parts of the western empire in the fourth century. Papyri also indicate that the production of Egyptian grain decreased in the later third century. The correlation is obvious, but the causation less so. Rome had an extensive system of supply of food for its armies and functionaries. The failure would have had to be systemic, and of this, we have no evidence. Barbarians and Christians? Gibbons’ thesis is attractive but has been widely disproved (see here for a survey of the evidence and two books that are worth reading). Any serious study must include a variety of factors.

The fall of Rome was not a linear process of decline either. It was dotted with rebirth and periods of prosperity. Ammianus Marcellinus saw the reign of Julian as ushering in a new era of prosperity, as did the rhetor Libanius. At a more local level, the monopoly over the gold currency enjoyed by the imperial administration meant that a new class of landowners acquired estates in Egypt. During the fourth century, Africa did enjoy a period of prosperity.

In other words, what historians saw and what contemporaries describe is rarely the same thing. It can be difficult, as Picketty describes in Capital, to distinguish between short-term growth and lasting prosperity. The same is true of political and cultural events. Julian was emperor between 360 and 363, and his passing led to a resurgence of Christianizing efforts by the imperial court, not a rebirth of traditional cults. New wealth accumulated was not necessarily distributed. A few extremely wealthy families in Rome controlled the land in Africa. Care for the poor was more than just pastoral rhetoric.

Which brings us back to the US of A. It is difficult not to see some parallels. Both are world empires. The moral rhetoric prevalent in today’s politics, whether to implement “new” policies of social welfare or to “return” to a more traditional age—which does not exist, but that’d be a topic for another time—echoes strangely the debate between Symmachus and the bishop Ambrose. Prosperity is being consolidated into the hands of a few, and individuals are in increasingly precarious positions (student debt for instance). Barbarians in California are revolutionizing social interactions (Facebook anyone?). At the same time, I am not entirely sure anyone can objectively speak of decline.
http://www.worldcrunch.com/culture-society/can-startups-change-the-world-a-french-alternative-to-silicon-valley/barbarians-tech-startups-hackers-entrepreneur-archipel/c3s18598/
This means that the Roman Empire, that collapsed some 1500 years ago, needs to be studied and taught. It is a powerful rhetorical example, one that is easily recognizable. A yet, the sort of abuse exemplified by Ben Carson’s article means that it is also easily distorted to pursue nefarious social goals. Empires do not fail because of morality: that was the lesson of Sodom and Gomorrah. Rome’s fall has undoubtedly yielded some important conclusions, for instance, about the behavior of individuals in times of crisis, or about the mechanisms of recovery. And Rome’s fall will undoubtedly unveil more historical and social processes as new research in that field continues to advance.

Interesting Perspectives

Find below is the link to a very good article by Philip Rousseau. Late Antiquity has existed in various forms (spätantike, le Bas-Empire, the Later Empire), but only since Peter Brown's The World of Late Antiquity, published in 1971, has Late Antiquity been an actual historical period.  Is it time for scholars to redefine our analytical lens?

At stakes, however, is the wider issue of periodization. Do periods still have epistemological value?

Palmyra and ISIS

Thanks to Tim Whitmarsh who wrote this beautiful article

http://www.theguardian.com/commentisfree/2015/aug/25/palmyra-tolerant-multicultural-isis-ancient-city-migrants-savagery

Loss of life should not be overshadowed by loss of monuments. There is, however, great sadness in the destruction of beauty.

The monuments are glorious: the great colonnade, the triumphal arches, the temple of Bel and the numerous tombs erected for the glory of the families. 
Sunset over Palmyra- From wikimedia.


But it is the culture that was developed in Palmyra that deserves attention. Palmyra was a merchant city, with warehouses situated along the Euphrates. It facilitated trade between the far-east and the Roman world. In many ways, it was the gateway to the west, and the gateway to the east.

Palmyra welcomed merchants from the Persian world, where they mingled with merchants from the Roman world. It was in this cosmopolitan environment, filled with Greek and Roman architecture that the family of Odaenathus rose to prominence. The destruction of the trade lines by Shapur (destruction of the warehouse at Charax and Doura-Europos) put Odaenathus firmly in the Roman camp. With the Palmyrene archers mounted on camels (it is not entirely true, but the ala camelorum is well attested), he besieged Ctesiphon, the Persian capital.

His wife Zenobia, after his death, would build an Empire in the Near-East. For a few years between 267 and 272, she controlled the entire fertile crescent from Armenia to Egypt (Egypt was conquered in 270). This is an impressive feat the Persians were never able to achieve. It took the legions of Aurelian to destroy the Palmyrenische Sonderreich.

As a young graduate student, I was absorbed in this world: its merchants, its structures, its leaders. The deeds of Odaenathus and Zenobia are recorded on the columns of the great Colonnade, placed aside the many caravans who posted messages of thanks to the caravan-leaders for carrying them safely across the desert. I imagined in glorious Palmyra, walking along alleys full of palm trees in a bustling city where spices and fine silks were traded. It was my imaginary orient.

Palmyra provided for me so many things. I imagined the spaces but I discovered the world through an academic lens. My research was fueled by my fascination for this desert city so full of people. It is through Palmyra that my professional life began.

I pray that this is not an obituary, that Palmyra will continue to overtake professional and amateurs alike. Because Palmyra can do that.

The Fall of Palmyra- Herbert Schmalz
Arabia's fierce and desolating horde
Rome's conquering eagle, Babylonia's sword
All we behold, but chief one form appears,
Rising radiant from the gulf of years:
Proud is her step, her dark eye varying oft,
Now flashing fire-now languishingly soft;
The jeweled crown well suits that brow serene
'Tis great Zenobia, Tadmor's glorious Queen.

I regret now that I discovered her through books.

Irrational Fears Taken from a Constructed Past: Rome and its Barbarians

-->
I was made aware of this article “Dequoi meurent les civilisations,” by Jean-Paul Brighelli, le Point 08/08/2015. For the sake of argument let’s translate a summary.

“While the theme of immigration is increasingly being required, Brighelli (the author) has read ‘The Last Days [of the Roman Empire],’ which discusses the fall of the Roman Empire in the West.”

I am not quite sure as to whether Brighelli’s review of Les Derniers Jours- La Fin de l’Empire romain d’Occident (Michel de Jaeghere, Belles Lettres, 26.90 euros) indicates Mr. de Jaeghere’s point or selectively choses to focus on the issue of the barbarians. Having not read Les Derniers Jours- but being relatively well-informed on the issue of the Fall of Rome- I will address Brighelli’s article, not de Jaeghere’s book.

The argument Brighelli puts forth is this: Caracalla’s edict gave roman citizenship to all inhabitants, therefore recruitment in the army was decreased, therefore barbarians, who, while Romanized “to the extreme” would nevertheless cause the frontier to crack. As Brighelli discusses, Romans stopped having children, unlike the barbarians; the wealthy retreated in their latifundias, leaving towns deserted and in need of foreign labor; schools were no longer open to everyone but the privilege of the wealthy. Let’s just end the argument here.

The Rhetor And Teacher Libanius
I cannot address ALL of the points. There is little to no evidence of the retreat of the elites in their latifundias in the fourth century. The elites were active culturally, economically and politically (Jones, The Later Roman Empire from 1954 provides a good overview. Recently, Peter Brown, Through the Eye of a Needle 2014 Alan Cameron, The Last Pagans of Rome 2013, in French, Carrié and Rousselle, L’Empire Romain en Mutations 1999). Schools were NEVER part of a program of the education of the masses. Literacy was low, yet it seems that there is evidence of a more widespread “functional literacy,” namely that individuals could decipher inscriptions without being able to read Homer (Harris, Ancient Literacy 1989; in French, Mireille Corbier, Donner à voir, donner à lire 2008). Hence, from the golden age of Rome to its fall, nothing really changed in terms of the inclusiveness of education (on late antique education, Edward Watts, City and School in Late Antique Athens and Alexandria 2006, see also Cribiore, The School of Libanius in Late Antique Antioch 2007).

What’s more interesting is the causal link between the edict of Caracalla and the collapse of Rome. According to Cassius Dio, “he made all the people in his empire Roman citizens; nominally he was honoring them, but his real purpose was to increase his revenues by this means” (Cassius Dio, History 78.9). According to Brighelli, the expansion of citizenship rights led to the barbarization of the army. The inhabitants of the empire, now citizens, decided to stop serving the state.

The process that began with the death of Marcus Aurelius, and outlined at length in modern scholarship, describes quite the opposite phenomenon. The local elites increasingly participated in government. These men were “equestrians,” or wealthy locals. Through a career in the army or in the bureaucracy, they could acquire a senatorial status through imperial favor. The Roman Empire became governed, not by the senators in Rome (and it really hadn’t since the end of the Civil Wars in B.C. 27), but by men from the provinces. Secondly, the expansion of the bureaucracy under Diocletian (284-303) increased the number of positions available for personal advancement. Imperial service, rather than local service, became the preferred choice of the local elites (if one is to trust the bitter rhetor and councilman of Antioch Libanius). That is to say, the history of the aftermath of the edict of Carcalla is not one of decay, but one of incorporation in all segments of society.

Trajan's Column:
A more important point, which thankfully did not escape Brighelli completely (but mostly), is that barbarian is an inherently perspectival term. The Roman Senate in the Republic was limited to Romans, and expanded slowly to include the provincials. When Caesar reformed senatorial membership in B.C. 46, “urban humor blossomed into scurrilous verses about Gauls newly emancipated from the national trouser”(Ronald Syme, Roman Revolution 1939). In other words, the Gauls were once barbarians. And Rome endured to have an emperor from Spain, another from Africa, one from Arabia and quite a few from the Balkans.

Which leaves us with a definitional problem: what is a barbarian?  Guy Halsall summarizes the problem quite well: “Much discussion of barbarian settlement is heavily technical, making considerable and precise use of Roman vocabulary and assigning constitutional significance to such terms. However, close inspection of the sources reveals that the situation was much less clearly defined.” Dediticii- barbarians who surrendered-, laeti- captured barbarians-, and foederati- barbarians who made a treaty for settlement- are various forms of barbarians. In many ways “the usurpers Magnentius (350-353) and Silvanus (355) were […] sons of barbarians. Had they not rebelled or found themselves on the wrong side of the imperial authorities- whereupon their barbarian antecedents were emphasized-, there would be no reason to see them as other than Roman” (Guy Halsall, Barbarian Migrations 2007). Thus a barbarian is a situational construction, which mostly involves a comedic aspect (the Roman emperor of Gaul Tetricus was made to wear the traditional Gallic pants when he was paraded in Rome as a defeated enemy by the emperor Aurelian).

And as a follow up question: how can we tell that an individual is a barbarian? In 1984, Yves-Albert Dauge demonstrated that barbarian is also a term for criticism used sometimes to  describe emperors (Yves-Albert Dauges, Le Barbare 1981). The barbarians, indeed, is the enemy of Rome, but that enemy can be anybody. Archaeologically, it is even harder to define what a barbarian is. Issues of language, religion, custom or law are difficult to unearth archaeologically, especially since, according to Brighelli, these barbarians are Romanized (thus spoke Latin, were Christians, and pretty-much behaved like Romans). Thus, the proposition that Roman population decreased while barbarian population increased is a completely untestable hypothesis.

What’s at stake is the problem that  “[de Jaeghere’s work] gives us a terrifying mirror.” What exactly is that mirror? That inclusion leads to ruin? That European culture, by opening its doors to immigrants, is going to die? What is, in fact, European culture? Who gets to define it? The danger in reducing the fall of Rome to a problem of immigration misleads the reader into making false assumptions about this society’s future (and about border control in the Roman world). Roman history does not indicate that incorporation was a problem, quite the opposite. If failure there is (and I don’t think there is) it was different. To ossify a system in such a way that prevents assimilation or denies integration can only be doomed. The increase of “knights” into the Roman state in the third century, the integration of local elites from all corners of the empire, allowed for greater participation in the Roman world of localities in the Roman World. In the fourth century, the Roman aristocrat(s) who wrote the Historia Augusta called the Syrian prince Septimius Odaenathus (who lived in the third century) restitutor orbis (the savior of the world) for his battles against Persia.

I am critical of Brighelli’s article, not just for the poor caricature he presents of the empire (which has nothing to do with his status as a journalist), but also for his lack of wherewithal regarding appurtenance to a “European culture.” In a Democracy, the relationship of one being to another being cannot be enshrined by the privilege of an individual or a body of individuals to decide appurtenance to a culture; and its logical afterthought, to deny opportunities and participation in a system on account of ever-changing definitions of identity that seek to exclude more than they seek to include.

To me, Brighelli demonstrated, once again, Professor Drake’s sentiment that “we always learn the wrong lessons from History.”

Foucault, Veyne and Graduate School

This is not so much an apology to the "métier d'historien," to borrow from Marc Bloch, or for that matter, a great insightful essay. Rather, it is a somewhat introspective realization from reading Foucault's Archaeology of Knowledge, and beginning a fun reading book Fooled by Randomness.

This particular point takes me back two years, a book by Elizabeth Clark (History, Theory and Text), and a rather nasty comment I made about the idea that historical facts don't matter. I was a young graduate student, in a quest for certitudes both professionally and personally, so the idea that historical facts a) don't exist, and b) even if they did don't matter was a rather disturbing experience. I could not "just leave it," despite my advisor's warnings (in French) "attention Laurent."

Two years later, a slightly different perspective emerged from my graduate work, and my duty as a historian. First, and I must thank a Professor a German History Professor at PennSt who chastised me me (as much as one can be chastised over a beer in a bar) for being far too destructive. He said, and I can only paraphrase, that we have come a long way since we assumed that we could look at texts without biases. Conclusion: stop being so critical. Methodological conclusion: each book has its value, if only (to be reductive of the books one truly hates) the presence of an argument built on a set of sources that is coherent and cogent.

Second, and this goes back to what I intended to write initially, historical facts do not matter, or rather, and this is Paul Veyne's caveat, they matter in a series. For instance, Louis XIV's death, while, as a student in the French high school system, an important date to be memorized (I can't remember the precise date), has no bearing on all aspects the life of Martin, paysan du Languedoc... that is, unless the question asked requires one to consider the death of Louis XIV.

So, my pursuit is to reorganize data sets to highlight different historical processes. Doing so, I cannot assume that what has been done (or is being done) is wrong, or even lacking. Simply their data set has its coherence, and it is different from my data set and its coherence.
