What's in a Medieval Arabic Grimoire
But YouTubers who talk about arcane religious topic love them, so I have lately been able to learn a great deal about them in a pleasant way. (I recommend Let's Talk Religion.) The most influential of the medieval Arabic grimoires was the Shams al Ma'arif, or Sun of Knowledge, supposedly written by the Sufi scholar Ahmad al Buni (died 1225). But it was not written by al Buni, any more than the equally famous Picatrix was written by Aristotle. The actual authors of these texts were not keen to draw attention to themselves.
The Shams al Ma'arif has long been considered a cursed book, dangerous to read or even to own. One of the YouTubers I listened to warned his readers when he was about to quote from it, so that any who feared the curse could skip that section. But I have no fear of weird old books, so let's dive in and see what this book, and other like it, actually say.
The first chapters describe how to construct magic squares, that is, squares of numbers that add up to the same sum in any direction. Really. As I have noted here before, this old trick of arithmetic has some kind of hold on the minds of many people.
Then we move onto astrology. This is the real meat of the work, and if you are not prepared for it you will likely be astonished at how much medieval magic is just about ways to leverage astrology. This focus is ancient; our oldest detailed spell books, in Babylonian, are equally focused on astrology. Astral magic is likely another of the Sumerians' legacies to the later western world.
If you ask, where does the power come from that magicians wield, the basic answer is, from the stars and especially the planets. (Actually it derives from the One, which the Muslims equated with God, from which it emanates through a bunch of levels and powers and thus into the mortal world, but in practice you get it from the heavens.)
You leverage this power through correspondences. That is, you find things that are mystically connected to the power you want to draw on, and construct a chain that binds that power into some object. Like this:To harness the power of Jupiter, which has a protective and fortunate quality, you construct a magic square. Take the letter associated with Jupiter, Dal, which has the numerical value of four. Make a four by four magic square. Then you write the letter itself, Dal, thirty-five times, which is the numerical value of the letter Dal written out as it is pronounced, Dal-Alif-Lam. You can also write various names of God that include that letter, such as al wadoud, “the Loving.” You then inscribe this talismanic symbol when the Moon is in a good and fortunate mansion in the sky, on a parchment or any other object that you can carry with you or hang over your door. You can also write it out with ink, then dissolve the ink in water and drink it. Thus one has harnessed the power Jupiter by using the infinite thread of correspondences, from the sphere of Jupiter to the letter associated with that sphere to the numerical value of that letter to the names of God that include that letter and so on.
Each of the planets is also associated with a metal (Jupiter is tin), so you could add another correspondence by making your object out of that metal.
Notice the emphasis on the names of God, of course an important theme in Islam. The reason al Buni had this magical text foisted on him is likely that he did write a Sufi text about meditation on the names of God, and this text ascribes semi-magical effects to the names and the letters that make them up. This aspect of relatively orthodox Islam was coopted into the ancient system of astral magic as another sort of correspondence.
If you want to do harmful magic, you can, for example use all these correspondences to bind the power of Mars or Saturn (in an unfavorable aspect) to a doll, which you then torture or maim and bury it near the victim's house, or in a place he will surely walk over.
If you want a woman to love you, you draw on the power of Venus (in a favorable aspect) and somehow channel that power either into an amulet that you wear, or something that you introduce to the victim, e.g., by burying it where she will walk.
The point is to draw on astral power through correspondences and find some way to direct that power toward the desired beneficiary or victim.
Oh my sagely readers, now that you have entered into the house of those that know, go forth and do magic to make the world better.

Lourenço da Silva de Mendouça
Lourenço da Silva de Mendouça was born around 1650 in the Kingdom of Ndongo in what is now Angola. Lourenço was the grandson of the King of Pongo, known in our sources as either King Hari or Philipe I. Hari/Philipe ruled from 1626 to 1664 over a breakway state that maintained its independence from Ndongo by allying with the Portuguese. As Portuguese allies, the royal family all of course converted to Catholicism. When Philipe I died, he was succeeded by one of his son, Dom João. According to wikipedia,
Dom João refused the annual tax of 100 slaves demanded by the colonisers, known as baculamento, and declared war against the Portuguese.
The Portuguese won the war and decided to send the rebel's family into exile in Brazil. They were not enslaved but lived in rather comfortable circumstances; Mendonça studied in a Catholic seminary. But the Brazilian authorities got suspicious of these African nobles, fearing in particular that they might ally with a free nation of maroons known as the Quilombo dos Palmares. (Maroons who disappeared into the jungle were a major feature of colonial Brazil, and some of their communities endured long enough to have their rights to their land recognized by a left-wing government in the 1990s.) So they split up the family, sending Lourenço and some others to Portugal.
Wikipedia again:
Mendonça was sent to the Convent of Vilar de Frades, in Braga, where he studied for three or four years, before moving to Lisbon.
Notice the importance of noble blood in this world. Mendonça may have been an African, but he was a prince (and a Catholic), so nobody expected him to work for a living.
Lisbon at that time had a significant black population, estimated at 5 to 10 percent, so the Pumbo royals were hardly alone in their situation. Many of Portugal's Africans joined confraternities, lay Catholic organizations officially devoted to chartity but also functioning as social clubs. In about 1681 Mendonça became the procurator general of the Confraternity of Our Lady, Star of the Negroes, a trans-Atlantic group that also existed in Brazil.
During all of these travels, Mendonça seems to have been working on a legal brief accusing Portugal and Spain of a great crime, the Atlantic slave trade. In 1684 he was able to travel to Rome and present his brief to the papal curia. Mendonça's brief was particularly strong on the gruesome tortures the Portuguese regularly inflicted on rebellious slaves. Mendonça's brief helped to convince Pope Innocent XI to issue a letter reiterating previous Papal condemnations against enslaving Christians and cruelty to slaves. He did not, however, condemn slavery itself.
Mendonça died in Rome in 1698.

Trump Is a Global ‘Wrecking Ball,’ European Security Experts Say
I know Trump supporters who would say, YES!!! The global order is a grotesque disaster and we elected Trmp to wreck it.
Support for Trump is driven precisely by the belief that things are terrible. Calling him a "wrecking ball" only encourages him and his fans.
What is needed is to somehow convince people that things are not bad and don't need wrecking. Assuming that is true does not help.

Government Measures Influence the Timing of Births More than the Total Number
This seems to be happening in Hungary now. The government's birth subsidies did encourage women to have babies, but now fertility is falling again and it seems those were just babies women were planning to have at some point down the road.

Lugdunum: Roman Lyons
Lugdunum, modern Lyon, France, was in Roman times the greatest city of northwestern Europe, with a population of about 70,000. It was founded in about 43 BC as a settlement of veterans from Caesar's wars. The spot is such a great one – at the confluence of two significant rivers, perfectly positioned to control overland trade from the Mediterrean to Gaul and Britain – that it ought to have beeen settled a long time before that. Archaeologists, alas, have had a hard time documenting this. There seems to have been a small settlement on a nearby hill, but when people dig in the rest of the Roman city all they find is Roman stuff. Numerous stray artifacts from the Iron Age have turned up, but no little evidence of buildings. One interesting thing that has been found is pits full of animal bones, such as might be left from a great feast. So the reigning theory is that in the Iron Age most of the site was a sort of fair ground where people from north and south met to trade and feast, kept neutral by not allowing anyone to build there.
Roman Lugdunum grew rapidly. It got a big boost from Augustus' campaign to conquer Germania, which began in 20 BC. Lugdunum became a major supply hub, and a network of roads was built or improved radiating out from the city in all directions. By 10 BC the city had a major aqueduct and a theater that seated 4,500.Emperor Claudius – above, on a coin minted in Lugdunum – had a great bridge built across the river, which required sinking the pylons deep through the swampy ground.One of the most famous objects in the Lugdunum Musée et Théâtres Romains is the Sarcophagus with the Triumph of Bacchus, carved around 200 AD and found in 1845.Bronze statue of Neptune known as the Neptune of Lyon.
The "swastika mosaic," excavated in 1911 from a grand villa within the city.

The Supercritical Carbon Dioxide Generator
But that doesn't make it the best technology for converting heat into electricity.
This brings us to the a new(ish) technology that may turn out to be much more efficient: the supercritical CO2 generator. These are similar to steam turbines but instead of water they use supercritical CO2. "Supercritical" means that the carbon dioxide is heated and compressed (84C, 74 atmospheres) until it turns into a "supercritical" state, sort of a very dense gas that behaves like a liquid. This dense fluid can spin turine blades more efficiently than steam, and it does not lose energy to the phase transition (liquid to gas) that uses up a lot of energy in a steam engine. Because the CO2 is so much denser, these turbines can be much, much smaller than those using steam:
The 10 MW US$155-million Supercritical Transformational Electric Power (STEP) pilot plant was completed in 2023 in San Antonio. It is the size of a desk and can power around 10,000 homes. [top photo]
The US Department of Energy has been funding research in this area for decades. The biggest problem they found was that supercritical CO2 corrodes steel, so that however efficiently it generated power, the system could not be made reliable or stable. Then a decade or so ago Sandia National Laboratory discovered that certain kinds of nickel steel were not degraded by supercritical CO2, and this launched a worldwide spate of experiments and innovations. Recently commercial generators have gone online in both the US and China, with claims that they are up to 50 percent more efficient that steam turbines.
This is the Chinese entry, a recently announced 30 MW system in a steel plant, which is using waste heat to generate power for the grid.Saturday, February 7, 2026
The Emerald Tablet
The best thing about this text it is the story of its discovery, which was included in both of those key Arabic manuscripts. The text was supposed to come from an actual emerald tablet that was found in the hand of a corpse lying on the floor of a tomb, in front of a statue of Hermes Trismegistus. In one manuscript this was the tomb of Hermes himself.
Which is the most Dungeons & Dragons story I know from the whole medieval age.

There is a permanent shortage of excellent engineering talent. It is the fundamental limiting factor in Silicon Valley.
This was in response to a poster who asked, "Genuinely curious: Are there actual instances where qualified native born Americans couldn’t get jobs in tech because foreigners took all of them? I’d be surprised if it’s true because at any given point there are hundreds of thousands of unfilled jobs in tech."

Most Penicillin Allergies are Fake
Just learned about this 2020 paper at PubMed:
Many patients report allergies to penicillin, although in over 90% of these the label of penicillin allergy is shown to be incorrect following comprehensive testing. Inappropriate and inaccurate penicillin allergy labelling is a barrier to antimicrobial stewardship and can lead to patient harm. This review assesses an emergent evidence base and trend favouring delabelling using direct oral penicillin challenges following a stratified risk assessment of the likelihood and existence of true penicillin allergy, to identify and make recommendations for key components for implementation in standard practice.
My Presidential Platform
I can sum up my platform with one noble word from a past era of American politics: normalcy.
After the woke madness and then the MAGA Madness, after January 6 and the George Floyd riots and the ICE assault on America, I promise to get America back to normal. No more video of fighting in our streets. No judicial persecutions, no threats to our electoral system, no trying to get people fired for their views.
I will promote a legal regime with no special privileges for anyone. If being a regular old American isn't good enough for you, go somewhere else.
My goal will be that unless some foreign crisis pops up, my name will appear in headlines only once a year, for my state of the union address. In those addresses I propose to talk about things like how many miles of highway have been repaved, how many acres of solar arrays have been installed, how many houses have been built. Otherwise I will devote my time to things too boring for most people to notice, like NEPA reform, improving the power grid, fixing our naval shipbuilding mess, and reducing corruption in Medicare and Medicaid.
I promise to pass a budget every year, on time. I promise to get the budget deficit headed downward.
I promise to appoint judges devoted to defending the constitution.
I promise to stay off social media and instruct my administration to do likewise. We will post only to make Americans aware of important developments, like changes in Medicare rules.
I promise that every activist in the country, of whatever stripe, will complain that my administration is not doing enough.
Thank you for your attention.

Immigrants and the US Budget:
Study from the Cato Institute:
The government first began gathering detailed information on benefits use by citizenship status in 1994. The data show:These results, which do not account for any of immigration’s indirect, tax-revenue-boosting effects on economic growth, represent the lower bound of the positive fiscal effects. Even by this conservative analysis, immigrants may have already prevented a fiscal crisis.
- For each year from 1994 to 2023, the US immigrant population generated more in taxes than they received in benefits from all levels of government.
- Over that period, immigrants created a cumulative fiscal surplus of $14.5 trillion in real 2024 US dollars, including $3.9 trillion in savings on interest on the debt.
- Without immigrants, US government public debt at all levels would be at least 205 percent of gross domestic product (GDP)—nearly twice its 2023 level.
Epstein and the Blood Libel
Matthew Schmitz at First Things:
The Epstein myth updates these lies for the age of Jewish statehood. It presents Epstein as blackmailing American leaders—not on behalf of a shadowy world Jewry, but on behalf of the Jewish state. And it recasts Jewish ritual sacrifice in terms of child sexual abuse. The anti-Semitic implications of the Epstein myth may not be widely acknowledged, but they are understood by many of the myth’s most important promoters.
Take Maria Farmer, an Epstein accuser who has been interviewed by MSNBC and respectfully profiled by the New York Times. She remarked in a recent interview, “All the Jewish people I met just happen to be pedophiles who run the world economy.” She is an adherent of David Icke, the UFOlogist who has promoted the Protocols [of the Elders of Zion] and suggested that the world is controlled by shape-shifting alien “reptilians” that merely appear to be human, including the members of the Rothschild family.
Similar claims are made by another Epstein accuser, Juliette Bryant. Maurene Comey, the prosecutor of Ghislaine Maxwell, submitted a victim impact statement from Bryant at Maxwell’s sentencing hearing. Apparently, the government regards Bryant’s words on Epstein as credible. This is a remarkable judgment. Earlier this year, Bryant declared on social media that she had “witnessed Epstein turn into an alien reptilian creature.”
Certain facts about Epstein are well established and incontestable: He committed sexual crimes against minors. He deserved to be punished, and more severely than he was. What goes beyond the facts is the Epstein myth. This myth is a synthesis of conspiracy theories: satanic panic, blood libel, the Protocols, UFOs. It generally presents its assertions in a respectable guise, but as its most enthusiastic adherents reveal, it tends toward the demonization of Jews.
I would say that the constellation of accusations floating around Epstein island lends itself to the demonization of all sorts of things, which makes it irresistible to many malcontents. For example, various female reporters seem interested because the story demonizes male sexuality. Populists see the global elite partying together on a secret island, the perfect metaphor for their view of the political world. Anti-semites see secret Jewish influence. Socialists see billionaires flaunting their immunity from the law. Nervous Christians see Satanic power; nervous crazy people see reptilian aliens.
Epstein was a sleazeball, a convicted sex offender who got rich helping billionaires avoid taxes. As the list of visitors to his island shows, there are a lot of sleazy men in the world, including two American presidents and a British prince.
But it turns my stomach when media outlets that ought to know better print allegations from Epstein "survivors", even when these women have had to recant their charges under oath. These professional accusers, all of whom were adults when they went to the island, got paid to party with rich men. Nobody forced them to sign up as island escorts. Now they play the victim for cash and attention. Maybe somebody was coerced into going to the island; maybe some of them were effectively raped once they got there. I have seen no evidence of this, but let's allow it is possible. The women in the news as accusers were not coerced and were not raped. They are just displaying the same kind of unstable mania for attention they showed when they went to the island in the first place. Reporters who quote them are indulging in outrage for its own sake.
Given all the important things that are happening in the world, can we please talk about something else?

La Mothe de Pineuilh
In 975 AD, a French noble family began constructing a new home in the hills east of Bordeaux. They chose a site along a marshy tributary of the Monsabeau River. Digging a circular ditch about 30 meters (100 feet) across, they piled the mud on the interior to form a platform. There they lived for about 150 years. That a wealthy family chose to live on a little island in this marshy spot tells you all you need to know about the security situation at the time. This was close to the nadir of public order and government power in medieval France.
A charter of 1077 records that some land in this vicinity was donated to the Abbey of Conques by a man called Falco de Barta, which may give us the name of this family.
In 2002, the French government began building a new road through the valley. This road, as it happens, ran smack across the site, ultimately destroying the eastern third of the mound.
But before that happened, French archaeologists took a close look at this wonderful site. They discovered that around 1043 (these are all tree ring dates) the ditch was deepened and the height of the mound was greatly increased, forming a "motte" like those you may know from Norman England's motte and bailey castles. This had the effect of burying and thus preserving the earlier occupation of the site. A plan of the early phase is shown above. Notice the three bridges that cross the river to the mound, only one of which would have stood at any given time. The marshy ground around those bridges was full of artifacts, inlcuding objects of wood, horn, and leather preserved by the wet environment.Detail of the mound area. Notice that there were only two buildings in this section of the mound: an outbuilding at the end of the bridge, possibly a guardhouse or stable, and a large timber hall. This noble French family lived mostly in one great wooden hall like Vikings would have.Much less evidence survived of the later buildings, since they were built on top of the mound, which has eroded considerably since the site was abandoned. But the mound preserved the early period wonderfully, and the marshy ground preserved these wonderful artifacts.
One technical detail the archaeologists were able to work out was that the residents kept reusing wooden beams as they tore down some buildings and built new ones, so that any given structure of the later period might include beams from 975 was well as others that had been freshly cut.Makes me wish I could teach early medieval history again, so I could share this with my students.
