24. I feel modern scholars discount the importance of the stars in ancient lives because we cannot see them through our own light pollution.

There was plenty of innovation in the Middle Ages, we just don’t notice many of it and a lot of it was societal and economic and not purely technological.

Were the Knights Templar responsible for the international growth of the Champagne Fairs? They seem to have been involved in Champagne and to have played some key roles before the fairs grew to intl importance and the Italians started coming in the late 12th c 👇

So the English stole a bunch of Irish land and gave it to English landowners. Plan was for them to recruit English tenants to farm. But the new owners realized they could charge much higher rents to the Irish who wanted to stay on their land than to new English recruits. King James was pissed.

For the #IdesofMarch, here's one of the most famous coins to ever be minted: the silver denarius of M. Junius Brutus commemorating the assassination of Julius Caesar. It depicts two daggers, a slave's cap of freedom (pileus), and the inscription EID MAR. 🏺 #ancientbluesky 43-42 CE. #MetMuseum 📸 me

The Ides of March denarius, issued by Marcus Junius Brutus, is one of the most famous and historic coins ever minted. It commemorates the assassination of Julius Caesar on March 15, 44 BCE, an event that later inspired many works of art, literature, opera, and film. Caesar had declared himself "perpetual dictator" at the beginning of that year, thereby directly prompting the assassination plot by Brutus and a group of other senators who feared for the survival of the Republic under his tyrannical rule. The reverse of the coin shown here not only bears the inscription naming the day of the murder but also depicts two daggers representing the weapons used to stab Caesar to death, as well as a cap usually worn by slaves who had earned their freedom, symbolizing here the liberation of Rome.

Inscription: BRVT IMP L PLAET CEST (Brutus, Imperator, Lucius Plaetorius Cestianus), head of Brutus, EID MAR (Ides of March), pilleus (felt cap), and two daggers.

Rome, 43-42 BCE.

Working on a theory that the origin of British capitalism simply boils down to the propensity for growing oats. > The Irish grew lots of oats > The British colonized the Irish > The oats fed the horses > The horses plowed the fields > Boom: Agricultural Capitalism

Just learned about the Bazacle Milling Company. First recorded European joint stock company, from 12th c. Shares traded freely. Lasted until it was nationalized in the 20th c! Water mills were very profitable and serious business in medieval times

Sometime back I made a (wildly incomplete) map of economists and their influence (green), mentorship (blue), and disputes (red). Focus is on the heterodox schools and the relations between them. Impact of the Austrian line is astounding.

I can't recommend Mimbres School enough to avoid this mentality. Come read some actual books! I'm teaching a course about animal domestication there next summer.

This little manuscript is a king’s order from the year 1272 to pay his court jester. King James I of Aragon paid around 100 pieces of silver to Martynus, labeled in the document as a “joculator”—literally, “a person who jokes.” The king’s royal seal is affixed to the back. #medievalsky

I've long believed that everyone on the TTC board (and preferably the entire Council) be required to take TTC from their home to City Hall once a month. The reality of transit commuting would hit home and service levels would increase. H/t @shawnmicallef.bsky.social
