Ancient Web: Encyclopaedia Romana Has Been Wandering Through Rome Since 1997

Encyclopaedia Romana is what happens when a reference work refuses to stay in its lane.

Visit Encyclopaedia Romana

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.

Ancient Web: Roman Aqueducts Is a Private Engineering Library for 2,000-Year-Old Water Systems

Roman aqueducts are usually reduced to one photograph: a beautiful row of stone arches.

Visit Roman Aqueducts

RomanAqueducts.info is interested in everything that happened before and after the arches.

The private site was assembled by enthusiasts including Wilke D. Schram, Cees Passchier, and Driek van Opstal. It contains detailed information on more than 100 selected aqueducts and a literature index covering roughly 600 Roman and some Greek systems.

Then it keeps going.

The plumbing is the interesting part

There are historical and technical introductions, statistics, maps, photographs, bibliographies, aqueducts on Roman coins, distribution basins, siphons, control elements, qanats, gradients, channels, reservoirs, and individual system pages.

One entry for the Cologne aqueduct lists a route around 95 kilometers long, roughly 130 kilometers in total when branches are included, along with cross-section, estimated volume, gradient, and engineering features.

This is why the site works.

The Roman achievement was not “they built arches.” The achievement was surveying a route, finding a usable source, controlling slope, crossing valleys, tunneling through terrain, managing flow, handling maintenance, and delivering water where people needed it.

The authors are also refreshingly clear about uncertainty. The introduction notes that sources can contradict each other and invites corrections, especially where the team has not personally visited a site.

That is better historical practice than pretending the old literature magically agrees.

For webmasters and researchers, the site is another example of what happens when a narrow subject is allowed to become deep instead of broad. A general history site might give Roman aqueducts five paragraphs. This one gives them an ecosystem.

Roman Aqueducts was found through CacheRat’s larger Ancient Web research corpus.

The arches get the postcards. The engineering gets the website.
