Charny and the Law of Arms
For Geoffroi de Charny, writing around 1350, there were three elements to the law of arms.
The first was custom: what did experienced men at arms think would be expected, absent an explicit offer or agreement otherwise?
The second was explicit agreements or promises: such as the mention of specific rules in the announcement of a particular joust. In the 14th century these left so much unsaid that Charny must have expected customary precedent to do most of the heavy lifting, and that an experienced jouster would have a mental template of more or less how a formally announced joust would be run.
But just like judges of Common Law today, Charny's judges would often encounter disputes where neither unwritten precedent nor written rules gave a clear answer, and they would be forced to decide by a combination of analogy and their own intuition of what was just. This would then become part of the body of precedent used by future judges.
Interestingly, the branch of modern law most like Charny's law of arms may well be the law of war, which is still strongly rooted in customary norms.

How Jousts Were Structured Ca. 1340
I was asked how jousts were structured around 1345. Since I'm answering, I'll share the answer.
It's understandable for a modern reader to think that the winner was chosen by something like the modern elimination tree or round robin tournament.
Understandable, but wrong.
Here's what we know. Although jousts were individual contests, the contestants were always divided into two sides, typically called dedans and dehors, literally within and without but perhaps best translated as the home team and visitors. 15th and 16th century English joust announcements would refer to challengers and comers.
The traditional division dated back to the time when jousts were preliminary events attached to mounted melee tournaments between two teams, and persisted when jousts became independent contests in their own right.
Once jousts became an independent event, the sizes of the two teams were often asymmetrical: the home team was often determined in advance, but the visitors were who turned up on the day of combat. Each visitor could run some number of courses, that is to say attack runs with the mounted lance, against a defender. At the end of the jousts, winners were chosen.
We have one set of rules for scoring a joust from Spain ca. 1330. Different regions almost certainly ran jousts somewhat differently. Geoffroi de Charny's Questions suggest that choosing a winner in a French joust was somewhat more subjective, although it probably followed a roughly similar ranking of achievements.
Charny's Questions, translated in Steven Muhlberger's Jousts and Tournaments, is a valuable but frustrating source on French jousts and tournaments around 1350: frustrating because Charny lists various debatable questions about the martial sports without providing answers.
Still, his questions make it clear that in some, but not all, French jousts a man who unhorsed an opponent would win his horse, and that there were jousts for knights and jousts for squires, and that they involved different equipment. It seems likely that as at the later Smithfield jousts of 1390, the knight's joust was run in full armor and the squire's joust used a saddle that protected the legs and made leg armor unnecessary. Flemish records from the 1340s list prizes given to the best knight and best squire on each team.
Interestingly, Charny examines the question of a squire entering a knight's tourney and vice versa. He regards this as somewhat irregular, but not so much so that the interloper would clearly forfeit his winnings. He might or might not: he thought the question worth debating
Often the home team would be dressed in matching livery.
Charny describes a very informal process for assigning opponents: the visitors would line up on one side of the field and as soon as one of the home team rode forward one of the visitors would charge him. Because of their limited visibility with helmets on, sometimes two visitors would unintentionally charge at once.
The biographer of the Castillian knight Pero NiƱo noted the same informality when he jousted in France around 1405, contrasting it with what was presumably Spanish custom. "There is neither one that holds the lists, nor joust of one man against another by champions assigned"
There seems to have been a general agreement that someone that killed or injured another's horse usually owed compensation. For Charny, the possible exceptions seem to have been insufficient promtness in presenting a claim, the injuring party possibly acting as an agent for another person, damage to a borrowed horse, and damage from a dropped lance the jouster no longer controlled.

A Compromise Is When Both Sides Give Up Something They Want
In contrast, the House Republicans are offering to give up something they say they don't want, shutting down the government and/or defaulting on our debt, in return for the House minority, the Senate majority and the White House giving up various things that they do want.
You keep using that word. I do not think it means what you think it means.

Changing Laws
Under the U.S. Constitution, there's a minimum requirement for passing a new law or changing an old one. You get a majority in both houses of the legislature, and consent of the President as executive. If the Senate thinks it's very important, you need a supermajority there (Currently, the Senate seems to think that very important=almost everything.) If the President objects, you need a 2/3 majority in both houses. Even so, a law that passes can later be declared unconstitutional by the judiciary.
At this time, the Republicans in the House of Representatives are proposing an exception to the above going forward: that as long as a party with a majority in only one house wants something badly, they can refuse to pay for any non-mandated spending, in hopes that everyone else will give them what they cannot get through the regular constitutional process.
Whatever you may think of our current Constitution, with its potential for gridlock and lack of clear accountability, the House Republican variation is much worse.

A Great Week in Space
Today, SpaceX successfully launched the first flight of the significantly more capable v1.1 version of its Falcon 9 launcher.
Also, Orbital's unmanned Cygnus spacecraft successfully berthed with the International Space Station, bring supplies, including chocolate. The United States now has two different privately designed and built spacecraft that can do this.
And earlier this weekflight engineer Karen Nyberg sewed a toy stuffed dinosaur out of cloth scraps for her three year old son and it is adorable. It was made from materials salvaged on board the ISS, and is believed to be the first stuffed animal made in space.
A more powerful launcher, new private supply spacecraft, chocolate, and a stuffed dinosaur. In spaaaaace! Yay us!

Hatmaking

Here is what I have learned about hatmaking so far.
1) Obtain or order at least one hat body. This is the unblocked, crudely shaped proto-hat.
Hat bodies come in two basic shapes. One is the hood, shown in the first picture above. It is roughly conical, and optimal for hats ranging from brimless to a moderate brim. The second is the capeline, which has already been shaped to include a broad, flat brim, and is the optimal starting point for a broad-brimmd hat. I've been able to make a broad-brimmed hat from a hood, but it's more work, and you can get a broader brim starting with a capeline.
You also have two basic choices for material, wool felt or fur felt, usually rabbit fur. The top photo shows a fur felt hood in the center flanked by two wool felt hoods. Fur felt is stiffer, crisper and less floppy, and costs at least twice as much as wool felt. In the 21st century, fur felt is the norm for a fedora of good quality. High quality medieval hats, like that of Chaucer's merchant, were made of beaver fur felt. The greater stiffness of fur felt is particularly desirable for broad brimmed hats.
You can also buy long hair fur felt bodies. The hair is visible and palpable on one side instead of being processed into a smooth surface. This can be a pleasant effect on the inside and upturned brim of a hat, although this kind of felt seems a bit less stiff than regular fur felt.
If you're going to the trouble of making or buying a hat block it seems sensible to order several hat bodies. Leko has a good assortment of bodies and other millinery supplies.
2) Make or obtain a hat block. Wood is traditional. I carve mine from Owens Corning pink polystyrene insulating foam with a bread knife and finish with a sander and a sanding block. I made my first block with expanding foam filling a masking tape skin. It's softer than the pink foam and doesn't sand as smoothly, and I no longer use that kind of foam for new blocks. Remember to clean your block after sanding before you block with it.
Hat Shapers sell inexpensive ABS plastic hat blocks. I don't know how well they work, and they don't have all the shapes you'd want for medieval hats, but some look applicable. If you try them, let me know how they work for you.
Having separate crown and brim block pieces increases your flexibility. I can also remove the top piece of my Robin Hood crown to make a flat-topped version.
3) With my current blocks, I finding wrapping the crown or, in the case of the Robin Hood hat, the entire block with cling wrap makes it easier to force the body over the block and remove it later.
You will want an elastic hairband big enough to pull over the circumference of the bottom of the crown. If you are making a hat with an upturned brim a salad spoon like the one shown in the second photo is useful for working between the crown and the brim: a long handled shoehorn will also serve.
With everything gathered, I fill my bathroom sink with the hottest water I can get from the tap, putting the body under the tap like a bucket. When the crown is full I tip it over and submerge it, weighing it down with a full water glass. I let the body soak for severable minutes until it is pliable and easily stretched.
Let me start with a Robin Hood hat.
I pull the body from the water, letting some of the water drain off. I make a first guess at turning the brim up and force the body over the block, pulling and pushing it downwards until it conforms to the block, and moving the turn of the brim upwards or down as needed. Use the salad spoon as needed to pull the crown downwards behind the brim. Slide the elastic hairband down to bottom of the crown.
Now grasp the front of the brim with one hand while you brace the heel of your other hand against the front of the crown just above the bill. Pull the brim forward and down until it conforms with the bill of the block.
At this point the upturned part of the brim may not be turned upwards as steeply as you want. You can pin the bottom of the brim against your work surface with the salad spoon while pulling the upper edge upwards, stretching the felt. Start at the center rear and work gradually to the front on both sides. This may create some puckering at the top edge of the brim: smooth that out.
Update: If the upturned brim needs additional shaping, I now find it easier to mold the brim over an extended brim block before turning it up, as shown in the last photo. You may want to compress the brim over the bottom of the block with another elastic hairband.
Try to work quickly: the body will soon become harder to work. You can re-soak the body if you need to do more blocking.
Let the hat dry before trimming away excess felt. I let the hat dry on the block until it can hold its shape and then stand it on a glass or round Tupperware container as a stand to complete drying.
The second photo shows the block for a Robin Hood hat and blocked hats before and after trimming away excess brim.
If you start with a capeline a broad brimmed hat should be simpler. Pull the body down over the crown and stretch the elastic hairband over the bottom of the crown. You may need to temporarily turn the brim up to get clearance to complete pulling the crown onto the block. Then pull and stretch the brim down onto the block brim. The third photo shows the block and the narrower brimmed hat produced from a hood body in the center, with a hat made from a capeline at far left.
The 4th photo shows three hats made from low crowned block without a brim block, and the block.
At far left the body was pulled onto the crown and the brim turned up, and an elastic hairband pushed down to the bottom of the crown. I placed a belt weight leather spacer between crown and brim at the top of where I expected to trim the brim, and an elastic hairband over crown, spacer and brim at that point. I tugged the brim upwards from above that point until I created a narrow vertical brim without puckers. The excess was then trimmed away. This simple cap was worn by peddlers, laborers, small tradesmen, cooks and bakers by day, and by gentry as a nightcap.
To its right is a simple brimless cap, often worn by clergy and scholars, and sometimes by other laymen.
The third used the low crown block without a separate brim block and a single layer of wool felt. In blocking, wet felt was pulled forward from the crown block to create a bill in front of the crown. I stretched an elastic hairband around the crown just above this bill to keep the hat body from being pulled away from the upper crown.
You can use two hat bodies in contrasting colors on the same block to recreate what is often seen in medieval art: a hat with a contrasting upturned brim or lining. Two cautions:
Not all commercial hat bodies are colorfast. If you want to make a hat using two layers in contrasting colors, it is well to know if either color will run in hot water.
Also, not all felts play well together. I recently tried to use a fur felt outer layer and a wool felt inner layer. They did not cooperate.
In contrast, two layers of wool felt were willing to become a single hat.
If the hat is too floppy stiffness can be added or restored with hat stiffener. One hatmaker warns that the felt should be absolutely dry before stiffener is applied, or white marks can appear on the surface. This agrees with my experience from before I read her advice.

More Felt Hats
The hat on the far left used a high crown block and a separate brim block, both hand carved from pink insulating foam. The body used is sold by Leko as a long hair fur felt hood. One side is smooth and long rabbit hair is visible on the other. I put the hair side inside and on the outside of the upturned brim.
The next used the same blocks, but without using the full height of the brim block in back, so the overall height is a bit lower. Two wool felt blanks in contrasting colors were used.
The third uses the blocks similarly with a single wool felt blank.
The last used a low crown block without a separate brim block and a single layer of wool felt. In blocking, wet felt was pulled forward from the crown block to create a brim in front of the crown.

Why Movies Set in the Past Are Rarely Entirely True to That Past
Even the best movies set in the Middle Ages don’t get the period entirely right. Sometimes the production designer doesn’t have the resources or expertise to do the costuming or other details properly, as in the low budget The Seventh Seal and The Navigator: A Medieval Odyssey. Sometimes the film is less about the period than something else. The Seventh Seal was set in the fourteenth century, but Bergman was primarily using the setting to show the sort of existential doubt and crisis of faith a Lutheran pastor’s son might feel in the second half of the twentieth century, with an allegorical personification of death substituting for unfilmable internal conflict. The 1964 Becket was mostly a way to talk about French collaboration during World War II without poking the recent wounds too directly.
Our sense of what is natural, stylish, or flattering is different from theirs, and this often shows up in the recreation of hairstyles and costume details, either unconsciously or because the production designer was afraid the audience wouldn’t accept or understand an accurate recreation. In an extreme case like A Knight’s Tale, the production designer deliberately modernizes the clothing and even soundtrack to make it more accessible to a modern audience even while retaining some properly medieval story elements. The movies can still be worth watching, but you need to be aware of their limitations as a recreation of the historical past.
And then, even if the director has been given an adequate budget, and isn't trying to use the Middle Ages as a way to talk about something else, and hasn't transposed elements of the past to make them more accessible to a modern audience, another challenge remains.
Movies are not made to lose money. Successful movies, like other drama, tell a narrative that makes sense to the audience, and create a plausible narrative arc that ends at the end of the movie with the audience feeling that they have achieved some sense of resolution or release.
Real history, on the other hand, is full of awkward digressions from a plausible narrative arc that ends at with the audience feeling that they have achieved some sense of resolution or release. A successful director will divert your attention from these, or omit them, or sweep them under the rug.
Shakespeare treated history the same way. If you had to choose between historical truth and effective drama, truth would lose.

Pay Grades in a Medieval Household 1390-93
When the earl of Derby went overseas in 1390-93 his accounts recognized the following pay grades for his following:
Knights. (militi) Important clerics like his chaplain and the archdeacon of Hereford who served as his treasurer for war were also paid at this rate.
Squires. (scutiferi) His two heralds, the master cook and the clerk of the kitchen were also paid at this rate.
Superior valets or yeomen. (valletti), Minstrels were also paid at this rate.
Other valets or yeomen.
Grooms (gromes)
Pages (pagetti) There were few of these.
There were three pay scales. The first, infra curiam, reflected the fact that the servant serving with the household enjoyed food, board and other perks in addition to cash wages. The second, extra curiam, recognized that a servant away from the household had additional expenses for food and lodging. The third, for men on active campaign, recognized the additional risk by paying the extra curiam wages for men serving with the household
The wages were, per day, infra/extra
Knights: 12 d./24 d.
Squires: 7 1/2 d.-6d/12 d.
Yeomen: 4-3 d./6 d.
Grooms 2 d./4 d.
Pages 1 1/2 d./2 d.
The earl of Derby was heir to a rich duchy. A lesser household would not have servants of knightly status, and typically paid servants of equivalent description less.
Kyngeston, Richard, and Lucy Toulmin Smith. 1894. Expeditions to Prussia and the Holy Land made by Henry earl of Derby (afterwards King Henry IV.) in the years 1390-1 and 1392-3. Being the accounts kept by his treasurer during two years. [Westminster]: Printed for the Camden society.
