Somehow it's been almost TWO WEEKS since I've mentioned _An Exposition Upon The Sphere of the Cosmos_, my forthcoming translation of Cecco d'Ascoli's commentary on Sacrobosco's _De sphaera mundi_ 😲 Pre-orders for the hardcover (shipping mid-July; epub/paperback available late June) are open now!

Here’s a video from the same podcast as linked in my previous post where you can hear the audio too. I love this because it really lays bare how LLMs fool us - but really they’re just slotting words into linguistic patterns that we’re familiar with. Genres like a podcast or LinkedIn post.

This is why you need human beings to handle things like translation and, yes, even transcription, because AI will constantly just hallucinate the text that its teaching corpus tells it SHOULD be there.

In the interest of celebrating small accomplishments, I have to share this: So, I've casually noodled around on guitar for years, but always bounced hard off of music theory. 1/2

Hey, co-author Mat Hadfield and I are planning to record a podcast episode discussing our new book, _An Exposition Upon the Sphere of the Cosmos_, the first English translation of Cecco d'Ascoli's commentary on Sacrobosco's _De sphaera_, and we want your questions! What do you want to know about it?

I got curious so I checked our catalog for anything by Cecco d'Ascoli. We don't have anything by him in our manuscripts, however we have a biography in a ca. 1600 Italian manuscript! It's been digitized, if you want to take a look find.library.upenn.edu/catalog/9924...

And if you'd like to know about the slightly later reception history of Sacrobosco's work, there's no better (or at least, no more entertaining) place to start than Cecco d'Ascoli... hadean.press/products/an-...

Over the next week or so, we’ll be doing a #SIMSseries on this 13th century Italian copy of works on arithmetic and cosmology by Johannes de Sacro Bosco (UPenn LJS 26). The first view of LJS 26 is surprising! The binding is modern, but the manuscript definitely is not. 🔗: https://bit.ly/41EAKFa

Have you ever wondered what medieval people thought they knew about celestial mechanics? Or what kind of titles appeared in a natural philosopher's library in the 14th century? Or maybe under which astrological conjunction you're most likely to be assaulted by a succubus? Find out here!

French researcher cracks 4,000-year-old Elamite script from Iran

86? I'm sure we can do better than that. 101 better, even.

Love a cheeky Latin phrase, but this one, from the Scots poem Ratis Raving in CUL Kk.1.5, is a new one to me: qui culpat manum scriptoris lambiat anum I'll leave the translation to the reader, but M.R. James calls it "a very rude colophon"

243. Earth's atmosphere encompasses the Moon, and may be implicated in water formation at the lunar poles. Take that, people who think the Moon is dead. 🧪 #PlanetSci #TabClosed2026

It appears that another edition and translation of the Summa Sacre Magice is in the works, book one of which has just been released. The fact that it includes the transcribed Latin text as well as an English translation makes this an invaluable resource to anyone studying or working with the SSM.

Sociological factors in the acquisition of individual religious beliefs.

If you've seen Alphonse Mucha's work (you have), the continuity is obvious. The fact that Mucha largely produced advertising media is also no coincidence in this respect.

a. Editors are crucial to the publication process. With just one exception, every editor I've had has either improved my book or notably improved my book. 2. Any publisher using AIs for editorial is not actually editing their books. Δ. In my experience, AI editorial like Grammarly is often wrong.

OK everybody, buckle up, because I've got BIG NEWS. _An Exposition Upon The Sphere of the Cosmos: the Astrological Nigromancy of Cecco d'Ascoli_ is soon to be published by Hadean Press! 1/x #medievalsky

Searching for images to illustrate an upcoming Secret Project, I came across this amazing semi-allegorical depiction of the Earth from the late 15th century. I love how modern it seems — a globe floating in space, complete with 3D-rendered buildings. [from BNF, MS Fr. 134]

Also, endnotes force me to use two bookmarks when reading, and I fucking hate it.

A wonderful photo showing the difference between what a castle normally looks like and after it has been restored to its former medieval glory! From bare walls to bright, colourful, fun painted walls! Château de Salignac is doing it right! More here: www.facebook.com/reel/1910404...

Joke answer: "Check, ch-check, check, check, ch-check it out"

Non-joke answer: "Of course,"

Sounds like it could have been the crucifix ground beetle (or similar species in genus Panagaeus), which evidently once led Charles Darwin to take an ill-advised course of action while out bug collecting. en.wikipedia.org/wiki/Panagae...

Hey, remember the classic 1996 science-fiction action film _Independence Day_? Sure were a lot of great scenes in that film.

Yesterday I plugged my publishers, now here are some of my most recent books! _A Similitude of Nature_ is my edition and translation of material from the 15th-century Italian astrologer-physician Giorgio Anselmi’s _Divinum opus de magia disciplina_. revelore.press/product/simi... 1/x

I hadn't seen this before. This is pretty remarkable. Earth and Moon in one NASA photo. ht @astrokatie.com

I wanted to call out the specific red flag issue here. The review from user Andrew says, "[T]hey are quick to take your money but never respond" - A PUBLISHER DOES NOT TAKE YOUR MONEY. Money moves *exclusively* from publisher to author.

Also, in case it needs to be said: I do not use any form of AI in my work. Not in transcribing the two to six hundred-year old manuscripts, not in translating them, not in the background research, writing, or editing. I'm not perfect, but the fruits of my labor are my own.

Apropos of nothing, now seems like a great time to shout out the indie presses that publish my books. Hadean Press deal in folklore and the history of magical practices, and they punch way above their weight in terms of both intellectual substance and production values. hadean.press
