The Early Iron Age Revival of the State, XXIX: Lazy Sunday Outline with Premonitions of Mortality
Two things, first, a very late change of schedule; second, a scary moment at the Silver Kettle Lodge as my 92-year-old father seemed to be failing after his vaccination. These mean that I do not have Sunday to work on my postblogging, although I am covering a mid-shift on time change day, and do have some extra writing time. And I am reminded that we do not live forever and I should get my intellectual life in order.
So here's a summary of work to date on Sacred Spring: The Early Iron Age Revival of the State and a brief outline.

The Iron Age Revival of the State, XXIV: Revelations of St. John of the Cross
My employer is serving fresh, hot turnover again, so if you tuned in this week to hear about the prehistory of the cubicle, I'm sorry. That would take too much organising time. Instead, we're going to go up on Mount Carmel and receive a revelation from St. John. Not the author of Revelations, notwithstanding my link, the other one. St/ John of the Cross, Theresa of Avila's disciple in the Camelites Without Hats movement. Okay, okay, "Discalced Carmelites," which turns out to be a reference to footwear, hence "barefoot at the head," for those into New Wave science fiction.
The story, as I have it, is that the Carmelites were one of a number of mendicant orders founded in obscurity in the 1100s, or, more likely, early 1200s. Claiming to be descended from eremitical monks living in isolation on Mount Carmel and preserving pre-Christian traditions going back to the Prophet Elijah, they plugged into a line of thinking in Christian natural philosophy that traced Plato back through the Seven Sages, some of whom studied in "the East," taken for these purposes to be Mount Carmel, and linking Greek philosophy -okay, okay, Neo-Platonism-- to the wisdom passed down from God to Adam and so on through the Hebrew tradition.
Hardly content within themselves as between raging debates over how much masochism to allow in the order, the Carmelites were thus possessed of one the weaker and more outrageous origin stories of a major Catholic institution in the age of intense controversy that followed on Luther. Cesare Baroni, one of the great names in ecclesiastical history, ruthlessly cut the cord, freeing Catholic apologists of the liability of defending the Carmelite account, at the expense of leaving the order without a history, and natural philosophy short one Christianity-friendly epistemology in the bargain. He also, unintentionally, engaged the ongoing dispute within the community. The upshot is that a Calched Carmelite named Paolo Foscarini took indirect aim at Baroni via his colleague, Roberto Bellarmino, in an arcane, ostensibly natural philosophical debate over the nature of the solar system, but, in fact, about possession of a Carmelite church in Rome, and a clause in the Tridentine reforms pertaining to the amount of plate a church was allowed to have. The dispute then drew in a Tuscan courtier, himself no stranger to artfully fanned pseudo-controversies bridging politics, Holy Writ, and natural philosophy, named Galileo Galilei, which is where yours truly, wearing his old historian of science, came on the scene, arriving via Biagioli's Galileo, Courtier, on the slopes of Mount Carmel, the 525m high, 39km-long, 7km wide "mountain range" along the north coast of Israel, cradling the city of Haifa and also the archaic site of Tel Dor.

A Technological Appendix to Postblogging Technology, July 1950: Achtung Panzerski!
The way in which mid-century land forces without air superiority consistently collapse for mysterious reasons of morale and leadership really is quite striking. But, of course, we're not here to hear about boring old Yak fighters and Ilyushin light bombers that only exist because mad air marshals want to strategically bomb nations into oblivion. (Not that that isn't a thing by Korea, but anyway.) We're here to hear about Panzer panic! American generals reduced to leading tank-hunting parties because their soft and undertrained troops have lost faith in their bazookas!
And, as the hitherto uncommented-upon marginal pictures suggest, the absolute wig-out conducted by the American armoured forces during the 1950s. I'm not going to delve too deeply into the industrial side of this story. The short design histories of the American tanks of the era discuss the manufacturers, factories, Congressional hearings and scandals that flowed from the tank panic. In instantiated terms, we have the M26 Pershing; the M41 Walker light tank; three tank designs named for General Patton, the M46, M47, M48 (Pattons); the M103 heavy tank, which never got named after anyone; and the T69, which seems to be the only one of three different T-series prototypes to get its picture in the news. That is a lot of new tank designs for a half-decade or so! From these we get a pretty clear view of what armoured forces designers considered important in the mid-Fifties, and alas for Overlord's blog, it is not unconventional armoured schemes.
And speaking of American narcissists, I guess Floating Tom Hutter really has taken his last dive. Now I should probably be realistic and go buy another copy of 2150AD.

Perhaps unlike them, Ibn Tumart climbed towards the wisdom of God, like a goat after an argan nut, travelling first to Cordoba in al-Andalus, and later to Baghdad, in search of Islamic learning. Which he found, it is said, at the feet of al-Ghazali. (The hagiographers really aren't that helpful.)
This map, which I scraped from an online thesis on colonial Morocco, does a good job of capturing the scale. |
Be that as it may, Ibn Tumart returned to the Maghreb by ship from Alexandria in 117/18. At Igiliz, at the end of Ramadan in 1121, he preached a fiery sermon in which he pursued weighty theological issues as well as the gravely immoral Almorad practice of veiling men and unveiling women, something with reverberations for our modern, masking times. Properly wound up, he proclaimed himself the right-guided one, the Mahdi, which implied levying revolt against the Almoravid regime. Promptly decamping to the high fortress of Timmel, in the midst of the Masmuda country. His cause united six nations of the Masmuda, closing the passes from Marrakesh into the Sous anticline.
At this time, Sijilmasa was the major northwestern terminus of the caravan trail from Ghana, and also a way station on the east-west route to southern Morocco from Tunis via Tlemcen. Although drawing itself apart from Almoravid power, it was a crucial waypoint on the trans-Saharan route to the Empire of Ghana and its gold, and the blockade was an existential threat to the Almoravids, although before the economic effects could be felt, ibn Tumart had led his tribesmen down to besiege Marrakesh and been ignominiously killed. It therefore fell to

Which is my point. The timing and context of the founding of Agadir, a Moroccan porty city that lies far to the south of anywhere I would had imagined.
If you were wondering. Well, that, and I had the Almohads confused with the Almoravids.

The Early Iron Age Revival of the State, 20: Green Mountain Boys

Given Libya's current difficulties, it isn't clear to me just how many tourists the tourist traps trap, but Shahat does have an international airport. Oil, wishful thinking, archaeotourists --I have no idea. Marsa Sousa is at the other end of what's probably a fairly spectacular road, given that it climbs from sea level to 300m in fifteen kilometers. For a modern traveller, the old town is nestled in the final switchback on the way to Shahat.
The fact that the back country road goes through Shahat rather than Cyrene makes me uncomfortable in calling old Cyrene a crossroads town, but it does seem to have been quite something. The area around the ancient ruins is graced by numerous sanctuaries and a necropolis of overwhelming scope (40,000 tombs before various modern depredations). The necropolis is a bit of a focus due to its victory over various feeble systematisation efforts of a series of archaeological investigators. There's a sense that we could learn a lot about it if we could just grapple with its sheer scale. All credit due to the sketch work of some of these guys, though! And to the modern Polish mission to Ptolemais, which has produced a major monograph summarising a century-and-a-half of half-ass efforts to cope with an overwhelming site, written by Monika Rekowska and translated by Anna Kijak. (There's a Libyan Studies?)

Modern Marj, and the old town that may or may not be Classical Barca. (By Smiley.toerist - Own work, CC BY-SA 3.0, https://commons.wikimedia.org/w/index.php?curid=27630656 |
Before I go to the cut, I'll note that in one sense, Cyrene is not unique. There's a very similar city, and it is in Cyrenaica, too. Barca and Ptolemaishave formed a similar pairing to Apollonia (Marsa Sousa) and Cyrene. One might be unique, but two is a pattern!

The Early Iron Age Revival of the State, VIII: Return of the Dead
That, of course, was a blatant attempt to work the 2008 crash into the conversation. Niall Sharples waits until the conclusion of his book to do it.
"It is a little easier to to explain how catastrophic the end of the Bronze Age was, given the collapse of the financial markets that devastated national economies in 2008. In the Bronze Age, bronze was as important as money is today; it connected people and created a system whereby other people relied on others to provided materials that were not locally available, animals when they were needed for consumption and sexual partners necessary for the continuity of human communities. In times of crisis, the credit built up through the long-term exchange of gifts would enable people to acquire the essentials to rebuild their lives. It also provided a way of classifying and contrasting people and communities by status and identity. The complex system of exchange relationships, and indebtedness, which had been operating for over 1,000 years, was completely undermined and abandoned at the end of the Bronze Age." (Sharples, 312--13.)

Olives are the definition of the Mediterranean diet. They also need to be cured in salt or lye. This isn't very relevant to this post, but it is your weekly reminder of the importance of the primordial chemical industry to subsistence agriculture during the EIA. |
Now, of course, I do not. On the bright side, my employer has conceded that it mishandled the process of reallocating employees from two stores that have been closed for renovations. I'm sure you don't want to hear the details, and I will draw a veil over the whole embarrassing exercise by pointing at one of our competitors --a major national corporation, which paid its CEO $8.5 million in 2015-- CEOs with buyouts of $15 million and $25 million paid in the millions-- defending itself on charges by blaming middle management, and fixing the price of bread for the last decade and more by offering everyone a free $25 gift card. It's not that I don't believe that middle management at Loblaws/Weston Bread didn't realise that price coordination is wrong. That seems par for the course in an industry that can take a week and a half to realise that no stores are ordering cranberries at Christmas because of a software issue, and not because it's a wacky thing that's happening for no reason at all that no-one can fix. It's that I no longer have five days off after New Years to write. And while the company now owes me three weeks off with pay, I have no idea when that's going to happen, or what that means for my writing "schedule."

Missing the Point: On The Economic Advantages of Eighteenth Century England
You will notice a "Blog Comment Follow-Up" tag this week.
And how! Anyway, this is Brad Delong quoting "the mysterious Pseudoerasmus" commenting on Robert Allen.
I love the work of Robert Allen... steel... the Soviet Union... English agriculture. And his little book on global economic history—is there a greater marvel of illuminating concision than that?... . . . Yet I always find myself in the peculiar position of loving his work like a fan-girl and disagreeing with so much of it. In particular, I’m sceptical of his theory of the Industrial Revolution.
Allen has been advocating... [that] England’s high wages relative to its cheap energy and low capital costs biased technical innovation in favour of labour-saving equipment, and that is why it was cost-effective to industrialise in England first, before the rest of Europe (let alone Asia).... Allen’s is not a monocausal theory... but his distinctive contribution is the high-wage economy.... The theory is appealing, in part, because the technological innovations of the early Industrial Revolution were not exactly rocket science (a phrase used by Allen himself), so one wonders why they weren’t invented earlier and elsewhere. (Mokyr paraphrasing Cardwell said something like nothing invented in the early IR period would have puzzled Archimedes.) But... as Mokyr has tirelessly argued, inventions were too widespread across British society to be a matter of just the right incentives and expanding markets—and this is a point now being massively amplified by Anton Howes....
