I’m getting very little traction and reach today… please help with that? 🙏 If you can do nothing else, please reblog. Weekends are very hard for MA. And it’s been dead today too. I won’t be safe outside.

New release, a collab with my friend Borehole. Taking in blackened dungeon synth, discordant doom, and celestial choirwork. Central track is a strange improvisation that might sound like Essoupi meets Coil... a few copies of the tape remain! blaggardrecords.bandcamp.com/album/dark-v...

I had the pleasure of joining host Alexander Eth on the Glitch Bottle podcast along with my co-author Mat Hadfield to talk about our new book, _An Exposition Upon the Sphere of the Cosmos: the Astrological Nigromancy of Cecco d'Ascoli_! Find it on YouTube, or wherever you get your podcasts.

The Javascript ninja is lurking just off screen, preparing to strike at the oppressive HTML daimyo.

My very specific pet peeve is multi-CD sets in jewel cases, because manufacturers are completely arbitrary in placing the internal hinge on either the left or the right, and I'm pretty sure I've broken every one I've ever tried to open.

Mat Hadfield and I recently sat down to conduct a post mortem of our new book, _An Exposition Upon the Sphere of the Cosmos: The Astrological Nigromancy of Cecco d'Ascoli_! Come for the demonological astronomy, stay to hear us take Cecco to task for his sloppy citation practices!

So where can I find the guitar players / gearheads on Bluesky? Is there a starter pack for that?

Was reminded today that exactly three years ago I was just beginning work on the translation of Giorgio Anselmi's astrological-magical writings which would become my book _A Similitude of Nature_: revelore.press/product/simi...

Y'know, as an archaeologist, I understand that it can leave frustrating gaps in the historical record, but I'm really starting to come around to damnatio memoriae.

Hugely sad. We've lost John Blanche. It's hard to know where to begin. He set fire to a generation's imagination, and those fires show no sign of stopping burning. His work very much illuminated the darkness.

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!
