The old web was extremely good at one specific kind of behavior: somebody becoming obsessed with a subject and publishing the entire rabbit hole as linked HTML.
John Opsopaus did that with Pythagorean theology.
Visit the Pythagorean Theology project
Opsopaus is a writer and longtime practitioner of modern Pagan and esoteric traditions who has also worked in computer science. His site combines those interests in a sprawling study of Pythagorean and later Platonic religious philosophy, symbolism, ritual, theology, and historical sources.
The project should not be mistaken for a neutral academic encyclopedia. It is explicitly interpretive and reconstructive, and some sections move from ancient textual evidence into modern spiritual practice and esoteric theory.
That is part of what makes the site historically interesting.
It shows the web being used not merely to summarize scholarship but to build a personal intellectual system in public.
Hypertext was made for this kind of thing
Dense religious and philosophical traditions are full of names, symbols, cross-references, quotations, competing interpretations, and concepts that make little sense in isolation.
A linked website handles that naturally.
Opsopaus’s project breaks the material into sections and lets readers move sideways through related ideas rather than forcing everything into a single linear essay. The result feels closer to a private research notebook made public than to a modern SEO article.
The site has also had a long afterlife through citation and discussion. Forum posts and later blogs still link directly into individual chapters. A 2024 podcast appearance by Opsopaus points listeners back to the same site and specifically to the first chapter of the theology project.
That is more than simple survival.
It means the old URL is still functioning as the author’s reference edition decades after the web around it changed.
There is another useful lesson here: preservation does not require agreement.
A researcher can treat the site’s historical claims critically while still valuing the artifact. The important thing is to preserve what the author actually argued, how the argument was organized, and which sources and interpretations were connected together.
CacheRat’s 1,967 Ancient Web Domains research list exists for pages like this because unusual intellectual projects are especially vulnerable to disappearing once the person maintaining them stops paying for hosting.
The modern web likes short answers.
Opsopaus built a labyrinth instead.
