When were family-tree diagrams invented? Mind's Eye discovers the progenitor of today's graphic timelines and trees in an ancient three-meter chart of history. Hidden in plain sight, this Roman masterpiece has never been honored at book length before. The Great Stemma was not only a vast visual abstraction of the march of time from Creation as far...
Article
This is the first of a series of articles which test the hypothesis that the Tabula Peutingeriana may have been created in Roman Africa, not in Rome. Although no more than 800 kilometers long, the coast from Numidia to the Tripolitanian border occupies nearly half the chart's width and is laid out in exacting detail. Its fortifications, the Limes,...

The Piggin Stemma is an SVG document that reconstructs the fifth-century Great Stemma, presenting it in a modern idiom as a digital document with regular typefaces, strict graphic alignments and twelve explanatory overlays. This is the most complete edition to date of this late antique diagrammatic chronicle of biblical history and genealogy, and t...
Book

A structured edition of the Liber Genealogus of 427 CE, a Latin Christian work. The layout shows both the lexical character of the work, with lemmata and definitions distinguished, and its chronographic character, dividing the text up into biblical episodes. The entries are linked to the matching pages of the St Gall manuscript (Cod. Sang. 133) whi...

Hermann Schadt's magisterial study, Die Darstellungen der Arbores Consanguinitatis und der Arbores Affinitatis, published in 1982, is the definitive guide to the arbor juris diagram from its beginnings in classical Rome up to the present. Unfortunately Schadt's guide to the types he distinguishes is itself complicated and difficult to use. This man...
Data
The Ripoll Bible at the Vatican contains a remarkable text-only abstract of a lost historical and genealogical diagram which had apparently been compiled hundreds of years before this bible was made in the 11th century. Published here for the first time, the Latin text enables us to reconstruct that lost chart of biblical history, understand its th...

Isidore of Seville wrote the book Quaestiones or Expositio in Vetus Testamentum in about 600 CE. Previously unnoticed by scholarship is an epitome of the book only one-twelfth as long, written in the interstices of a biblical-history diagram dating from about 175 years earlier. This anonymous text survives in prefatory matter to four medieval bible...

A previously unsuspected 4th- or 5th-century Latin work by an unknown patristic author emerges through re-examination of the so-called genealogical tables found in certain medieval Spanish bibles and Apocalypse commentaries. Analysis of its text and layout suggests that this diagram, which I name the Great Stemma, began as a unified chronological c...

Project
The Tabula Peutingeriana (Vienna, Nationalbibliothek, Codex Vindobonensis 324) is a visualization of pre-existing Latin itinerary data. The project aims to discover the techniques used by its designer in compiling the data and giving it graphic form. The findings may illuminate the diagrammatic turn in late antiquity which also created the Great Stemma and legal and philosophical diagrams.
