Encyclopaedia Romana is what happens when a reference work refuses to stay in its lane.
James Grout first posted the site on April 17, 1997. Nearly three decades later, he is still revising it. The homepage carries a 1997–2026 copyright notice, and the project was updated again in 2026.
Calling it an encyclopedia is accurate, but it undersells the structure.
Grout describes the site as a collection of incidental essays on Roman history and culture. The important word is incidental.
A page about one subject leads into another, then another. Roman Britain wanders into the Norman period. Essays branch into Greek architecture, courtesans, paganism, the Viking Age and Byzantium. Grout’s own preface mentions Cleopatra’s pearls, red mullets, lead poisoning, tulip mania, Nero as the Antichrist, Caesar’s giraffe and conchylomania.
He also notes, with some pride, that there is basically nothing on Roman politics or economics.
Hyperlinks as a research method
The site works because the digressions are not treated as mistakes.
A modern content system would probably split every subject into a keyword-targeted article, add a recommendation widget, and attempt to predict the reader’s next click.
Encyclopaedia Romana just links the thought that naturally follows.
That makes browsing feel closer to following footnotes through a physical library. You may arrive looking for an aqueduct and leave knowing why Romans cared about purple dye, poisonous plants or an obscure statue type.
Even the interface has become part of the experience. Grout jokes that a frame-based design might have been more elegant, but scrolling through the essays has the pleasing anachronism of scrolling like the ancients.
That sentence could almost serve as a manifesto for the surviving personal web.
CacheRat’s broader 1,967 Ancient Web Domains research list contains many sites built around this same idea: a knowledgeable person follows a subject farther than a commercial publication would justify.
Encyclopaedia Romana has been doing that since 1997, and it is still being edited in 2026.
The remarkable part is not that the design survived.
The remarkable part is that the curiosity did.
