I was just thinking about this piece again the other day, on the ways in which 13th-cent. monarchs treated pardons much like they treated their almsgiving, so that Hen. III could pardon a homicide "for the salvation of the soul of Louis, first-born son of the king of France." I enjoyed writing it

Sometimes working with manuscripts gets us really, really close to the people from the past allowing us to hear their voices. This is a story of a letter from a schoolgirl to her teacher, written probably sometime at the end of the 9th or the beginning of the 10th century. A thread 🧵 #medievalsky /1
A faint writing, the text is in Latin and it reads: Domina magistra felhin date mihi licenciam in hac nocte vigilare cum magistra adalu et ego vobis ambabus manibus confirmo atque iuro ut per totam noctem declinare volo aut legere aut pro seniore nostro cantare Valete et ut peto facite.

Murder at the Medieval Mill Medieval millers were not always well liked and it’s not uncommon to read in criminal court records that a miller had been killed. This person leaving a windmill sure looks like they regret doing something nefarious at the mill with the mallet they're holding. 🧵1/5
A person wearing a dark tunic is leaving a windmill, presumably at the end of a hard day's work. The person is carrying a mallet and has a look on their face like they've done something wrong. Maybe they've killed the miller?

Correcting errors in medieval records: You listed the wrong person as a killer in a court record. What do you do? Well, you could draw a line through the name, as the clerk did in this homicide case from 1255 when he accidentally listed Walter le Stock as the killer instead of Walter Stuttuk. 🧵1/4

Medieval villages were often tasked with transporting people to gaol. This could be dangerous and expensive business. Friends and family of criminals could try to free the person through violence or bribery. And if a captive escaped, then the village would collectively be fined £5–£8! 🧵1/5
A group of people are in a procession in the marginalia at the bottom of a manuscript. There are eight people in total. The person at the front is playing a fiddle, while the person at the back is banging a set of drums that is being carried by (what appears to be) a child. The other five people in the middle are holding hands.

Cover of the book 'Marginalized Religion and the Law in the Roman Empire', by K.P.S. Janssen. The background is an ochre yellow. The bottom left side of the cover is taken up by an ancient relief of Daniel in the lions' den, depicting a naked Daniel with his hands spread, standing up to his ankles in a pit with a lion on either side. Two figures in tunics or togas are standing behind him, with one of them carrying a basket.

It's 1200, and you're the Abbot of Ramsey (congrats!). At Lent your tenants come calling with their annual rents of preserved eels. - 60,000 from Welles - 4,000 from Chatteris - 125 from Little Bedford - 5260 from Wisbeck etc. So what do you do with all of these eels? 1/4 🧪🗃️
Meme. Medieval drawing of a monk, leaning on a staff and holding a book. He has a thin tonsure, and a thin face, and thin fingers. His is holding the book open with his left hand, but in a very awkward way by his side. His fingers looks splayed like a spider on ice skates, and he appears to be holding his place in the book with a kind of death grip. By contrast, the hand holding onto his staff looks relaxed; it curls easily around the wood, and the monk appears to be leaning into it a bit. Either his desperation hasn't traveled to his right hand yet, or his chill hasn't made it to his left.

His robe is a lovely salmon color, but he's not thinking about salmon right now. He looks concerned, as if he has suddenly been given quite a lot of eels. He's been looking in copy of The Rule (aka. "Big Ben's Guide to Monking Around") for answers, but the saint didn't write about eels. He just ate them.

One of my favourite medieval laws: Concerning vampires (strigis), which do not exist, no inquiry shall be made. (From the early 12th-century Laws of King Coloman of Hungary, c.57)
The image shows Christopher Lee as Dracula, with blood on his lips and a victim in his arms. In the image, Dracula looks very troubled, perhaps because he’s just been told that he doesn’t exist by someone reading medieval Hungarian laws.
