Occult books digitized and put online by Amsterdam’s Ritman Library

A good place to start is Cornelis Agrippa’s “Three Books on Occult Philosophy.” Agrippa was a lawyer and esoteric feminist (eg, he wrote “on the nobility and preeminence of the female sex”) and defended women accused of witchcraft throughout Europe. His “three books” gave birth to the “occult” nomenclature.

Or my favorite, Marsilio Ficino. There is a statue to Ficino when you walk into the library. Ficino was hired by Cosimo Medici (the Florentine who invented banking and funded much of the Florentine renaissance) to translate Plato and other esoteric books coming from the fall of Constantinople. He published “De Mysteriis” in 1497, which paraphrases neoplatonic understanding of Gods, Demons, Heroes and Soul — arguing that gods and demons don’t feel — indeed, not even the soul (“the lowest of the divines”) has any part that feels.

(Aside: This idea was actually referenced in “K Pop Demon Hunters,” where they debate whether demons can feel — or are “all feelings”)

It is an old Pythagorean tradition that sensation or consciousness arises out of the interaction of the immaterial soul and the material body. That “three world” idea is echoed by Nobel Laureate Roger Penrose in his book “Road to Reality.” He talks about how the material world produces the world of consciousness which produces the world of ideas (including mathematics), which seems to produce the material world…

In any case, there are many old ideas and nuggets of wisdom that have yet to be mined and discovered— don’t think for a moment that scholars have read all these books! We might need AI for that…

This sounds like the premise for a fun sci-fi/horror move. Uh-oh; we accidentally trained GPT6 on the Necronomicon!

This is revolutionary. In my youth, I traveled through old libraries in Germany, collecting microfilm of Paracelsus’s works. Online availability could reshape the study of the early history of chemistry, metallurgy, and physics.

“Occult philosophy” is just the lens medieval societies used to make sense of the natural world.

The book club I do with my friends maintains a list of resources such as the one in the article. I would greatly appreciate it if anyone would take a look and suggest anything we should add.

Would this be reasonable material on which to fine tune the new Gemma 3 270M model?

I love the art aesthetic of occult texts, but browsing through all these books just to find any hidden gems or interesting artwork seems really tedious. At least browsing through the list with the title pages visible shows a few interesting designs. Can't really get much more out of this because most of the texts are unreadable to me. This might be a good use case for agentic AI, to browse through the books and highlight any artwork that's hidden beyond the first page.

For alchemy, I was recently learning about alchemical symbols and sigils, but quickly found out that pretty much all the interesting material from this era and category has been preserved, while all the ugly or uninteresting variants tend to get dropped. Unicode has a category for alchemical symbols and they just preserved what seems to be the best parts. Shout-out to U+1F756, the Alchemical Symbol for Horse Dung 🝖.

Whenever I visit a major news publication with dedicated artists handling the creation of hero images, I often end up taking a bit of time to contemplate each design decision and exploring any symbolic interpretation. The best publications have a way of perfectly communicating the underlying tone and message of an article just from the hero image. The Atlantic tends to have the most creative hero images, while The Economist has the most interesting cover designs. And yet, despite this expertise, I never see people remark on those little delights, which in a way makes it occult while hiding in plain sight. It feels a bit connected, seeing the artwork in the first page of these books; maybe an invitation with the whispers of the kind of message the authors wished to convey.

For those who don't know, this is the best digital library of Occult/Alchemical texts in existence.

Very cool, but I don't see a way to download. Currently have ChatGPT Agent Mode translating one from latin, but a tedious process.

Can anyone link a torrent? Would be nice to preserve this collection.

Looks like wonderful material to feed any AI crawler that accesses the forbidden part of my site.

Somewhat related, but I randomly got suggested this video on Youtube when it only had a couple hundred views. He's turned it into a series, and I have quite enjoyed it. Somehow bridges user interfaces and occult stuff haha

YOU can get lost in the metaphysical sauce and be left with an outdated, economically and socially irrelevant belief structure. Beware!

Does digitizing not summon demons like human reading can?

What if an LLM trained on that combines ancient spells with the name that must not be spoken?

At the bottom of the page:

> Note: An earlier version of this post appeared on our site in 2018.

Very confused by this. Seems like they uploaded the books in 2018? What changed between then and now?

Edit: The number of uploads was 1600 back in 2018 https://web.archive.org/web/20240615044608/https://www.openc...

Great now the LLMs are going to be able to cast spells on us, just what we needed.

This is super cool. There's also a popular YouTube channel called "ESOTERICA" in which an academic expert on the occult presents a lot of occult topics from a scholarly point of view (as opposed to the woo often associated with the topic).

Great, now we'll have AIs summoning eldritch entities before the decade is out.

Some people here are reacting like the occult is fake.

Magic is fake. It is an illusion and it is fun and games. And we have lots of stories about it, both fantasy and horror.

Occult is real. There is no such thing as white magic. There is only black magic. And such magic involves making trades with spirits and demons and establishing relationships with them. These demons do not have a code. They slowly guide you towards a state where you humiliate yourself and put yourself in a compromised state. Addicted. Disconnected. Repulsed.

Please be careful around these things. It’s fun until someone dies. As this professional witch will tell you. https://www.facebook.com/shadow.control.en/videos/zhanna-kus...
