mayan collapse

Mayan society experienced a gradual decline over three centuries

 

Is the collapse of a civilisation necessarily calamitous? The failure of the Egyptian Old Kingdom towards the end of the 2nd millennium BCE was accompanied by riots, tomb-raids and even cannibalism. ‘The whole of Upper Egypt died of hunger and each individual had reached such a state of hunger that he ate his own children,’ runs an account from 2120 BCE about the life of Ankhtifi, a southern provincial governor of Ancient Egypt.

Many of us are familiar with this historical narrative of how cultures can rapidly – and violently – decline and fall. Recent history appears to bear it out, too. Post-invasion Iraq witnessed 100,000 deaths in the first year and a half, followed by the emergence of ISIS. And the overthrow of the Libyan government in 2011 produced a power vacuum, leading to the re-emergence of the slave trade.

However, there’s a more complicated reality behind this view of collapse. In fact, the end of civilisations rarely involved a sudden cataclysm or apocalypse. Often the process is protracted, mild, and leaves people and culture continuing for many years…

Civilisational demise can also provide space for renewal. The emergence of the nation-state in Europe wouldn’t have happened without the end of the Western Roman Empire many centuries before. This has led some scholars to speculate that collapse is part of the ‘adaptive cycle’ of growth and decline of systems. Like a forest fire, the creative destruction of collapse provides resources and space for evolution and reorganisation.

One reason we rarely appreciate these nuances is that archaeology mainly depicts what happened to the lives of the elites – a view of history through the eyes of the 1 per cent. Until the invention of the printing press in the 15th century, writing and other forms of documentation were largely the preserve of government bureaucrats and aristocrats. Meanwhile, the footprint of the masses – such as non-state hunter-gatherers, foragers and pastoralists – was biodegradable…

But none of this means that we should be complacent about the prospects for a future fall…

The four big reasons why the next civilizational collapse might be both faster and harsher than many in the past: “Civilisational collapse has a bright past – but a dark future.”

As we contemplate change, we might recall that it was on this date in 1908 that “SOS”– “. . . _ _ _ . . .”– became the global standard radio distress signal.  While it was officially replaced in 1999 by the Global Maritime Distress Safety System, SOS is still recognized as a visual distress signal.

SOS has traditionally be “translated” (expanded) to mean “save our ship,” “save our souls,” “send out succor,” or other such pleas.  But while these may be helpful mnemonics, SOS is not an abbreviation or acronym.  Rather, according to the Oxford English Dictionary, the letters were chosen simply because they are easily transmitted in Morse code.

“From the moment I picked up your book until I put it down, I was convulsed with laughter. Some day I intend reading it.”*…

Codex Sinaiticus (4th century, eastern Mediterranean)

 

“Codex” is just the Roman name for a book, made of pages, and usually bound on the left. Its predecessor was the scroll or book roll, which was unrolled as you read. The codex is manifestly superior: one can hold many volumes (from the Latin for book roll, volumen); codices have a built-in cover for protection; and pages that can be numbered for reference, from which arose a cornucopia of tables of contents and indices.

The codex didn’t catch on until surprisingly late in the ancient world. The early Christians, however, took to the codex with singular enthusiasm. Wider adoption of this form seems to have corresponded to Christianity’s spread. In the 4th century, no less a figure than St Augustine illustrates the difference between a codex and a roll – and the nagging ‘Christianity’ of the codex.

Not yet baptised, in his garden where he had been reading, Augustine tells us he heard a child’s voice chant: ‘Tolle Lege!’ (‘Take up and read’). So he grabbed his book and flipped to a random page. His eyes lit upon a passage in Paul’s ‘Letters to the Romans’. The words he found were the key to his conversion. The book couldn’t have been a roll: it was a codex of the Gospels. But many of his other, often non-Christian books, were rolls.

Virtually all ancient Christian texts were codices, and with each new scrap pulled from the Egyptian sands, this has been confirmed, rare exceptions ‘proving the rule’. Historians have concluded that, while Christians probably didn’t invent the codex, their scribes had gifted the general use of it to the Roman world and, in so doing, passed it, and much of what survives of Classical literature, on to us. But an inability to explain the exact origin and nature of this ‘Christian codex’ clouds every investigation, and for good reason: this conclusion is wrong. While nearly every early Christian text is a codex, not every early codex is Christian…

The fascinating story in full: “The birth of the book: on Christians, Romans and the codex.”

As we turn the page, we might send speedy birthday greetings to Samuel Finley Breese Morse; he was born on this date in 1791.  After establishing himself as a successful painter, Morse returned to a school-day obsession, electricity, and began to experiment with using it to communicate…  sufficiently successfully that he is now less well remembered for his (then celebrated) art work, than for his success as contributor to the development of the single wire telegraph– which revolutionized global communications— and as the co-developer of Morse Code.

“The worst wheel of the cart makes the most noise”*…

 

The Stray Shopping Carts of Eastern North America: A Guide to Field Identification turns ten in 2016. Created by artist Julian Montague [bio here], the book attempts to bring clarity to a world littered with shopping carts far away from their birth stores. Written in the voice of a character who takes the project as seriously as a birder would take a birding guide, the book is as complex as it is wry…

A winner of the 2006 award for Oddest Book Title of the Year [c.f. this earlier visit to that list], Montague’s guide received a decent amount of media attention when it came out. But, published in the rudimentary years of social media, it missed out on a chance for the level of virality it may have achieved today. So far, there are few, if any, efforts to add to Montague’s research. Perhaps it’s too good. Perhaps it’s too insane…

See for yourself at “A Look Back at the Greatest (and Only) Stray Shopping Cart Identification Guide Ever Made.”

As we return our baskets to the queue, we might recall that it was on this date in 1904 that “CQD” (Morse code  – · – ·    – – · –    – · ·) became the official distress signal to be used by Marconi wireless radio operators. A few years later, judging that “CQD” was too easily mistaken for the general call “CQ” in conditions of poor reception, the signal was changed to the now-ubiquitous “SOS” (· · · – – – · · · ).

In 1912, RMS Titanic radio operator Jack Phillips initially sent “CQD”, which was still commonly used by British ships.  Harold Bride, the junior radio operator, jokingly suggested using the new code, “SOS”.  Thinking it might be the only time he would get to use it, Phillips began to alternate between the two.

All Reith Now!…

Bertrand Russell delivering the first Reith Lecture

The Reith Lectures were inaugurated by the BBC in 1948 to honor the contributions of its first Director General, John Reith (more formally known by the end of his career as “John Charles Walsham Reith, 1st Baron Reith”).

Lord Reith had operated on the principle that broadcasting should be a public service that enriches the intellectual and cultural life of the nation. In that spirit the BBC invites a leading figure to deliver a series of radio lectures each year– the aim being “to advance public understanding and debate about significant issues of contemporary interest.”

And so, over the last 63 years, British listeners have been treated to Arnold Toynbee on “The World and the West,” Robert Oppenheimer on “Science and Common Understanding,” John Searle on “Minds, Brains, and Science,” John Keegan on “War in Our World,” Marina Warner on “Managing Monsters”… and dozens more extraordinary minds explaining and provoking.

As of a few weeks ago the BBC has made the entire audio library of Reith Lectures available online, from Bertrand Russell’s kick-off through 2010’s Martin Rees on “Scientific Horizons.”

Hallelujah!

So graphic!…

As we attempt to keep X and Y straight in our minds, we might shudder to recall that it was on this date in 1883 that the volcano at Krakatoa (Krakatau) erupted with full force.  The sound was heard over 2,000 miles away (that’s over 7.5% of the earth’s surface– the equivalent of an explosion in New York City being heard in San Francisco); tsunamis caused by the great blast killed 36,000 people in Java and Sumatra.

But there was another sense in which Krakatoa was importantly “the sound heard ’round the world”:  While news of Lincoln’s assassination (only 18 years earlier) had taken almost two weeks to reach London,  Europe and the U.S. knew of Krakatoa in about four hours.  In the years between 1865 and 1883, there had been three interrelated developments: the global spread of the telegraph, the invention of Morse Code, and the establishment of Reuter’s news agency… and the world had become much smaller.  (C.F., Tom Standage’s marvelous The Victorian Internet for the details– both remarkable and altogether resonant with today.)

(As big as the explosion was, it was not the biggest in history: experts suggest that Santorini’s eruption in 1628 BCE was three times as powerful.)
