About

What this is

This site was inspired by our "Roman Personality" paper — a study in which we attempted to reconstruct a personality model from ancient Roman historical texts.

We used GPT-4o to code each incidence of person-description for whether or not the adjective in question was truly trait descriptive, and also for who that adjective pertained to. Then we used GPT-4.1 to disambiguate between these named individuals, merging those who were identical (e.g., "Julius Caesar" and "Caesar"), assign a birthplace to each person, and assign a religion to each person. Wikipedia was then scraped for the top image in relation to each person's name, and added that as their "portrait." This yielded some really cool, rich data, where for each individual we have a list of documents in which they appeared, and the adjectives used to describe them. I thought people might like to explore this data, so I built this website.

However, it's important to note that since the data processing was automated, there are occasional mistakes. People who are distinct sometimes get merged, people get the wrong birthplace assigned to them, some portraits are wrong (sometimes hilariously), and some adjectives aren't really used in the trait-descriptive sense (e.g., "Good Solonius" might get assigned "good" even though, in this case, it's just part of his name).

If you catch a mistake, please email me! If you like this work and want to see some of my other stuff, check out my website.

The corpus

The texts behind this site are English translations of ancient letters, biographies, histories, apologetics, hagiographies, and philosophical writings, spanning roughly 100 BCE to 800 CE. The core of the collection is the Roman Letters corpus compiled by Craig Vander Galien; to it we added further letters and a set of non-epistolary works, each drawn from the public digital editions listed below.

All 82 collections, grouped by provenance. Type: L = letter, B = biography, H = history, A = apologetic, G = hagiography, P = philosophy. Trad.: author's tradition (Pa = pagan, Ch = Christian). "Persons" = distinct people described in that collection.

† Jerome's 279 letters combine 148 documents from the Christian Classics Ethereal Library (CCEL) and 131 from the Roman Letters corpus. The "Persons" total counts each individual once across the whole corpus, so it is smaller than the column sum (many people appear in several collections).

A note on the texts

Everything here is an English translation, not the original Greek or Latin — so the adjectives reflect the translators' vocabularies as much as the ancient authors'. The pagan works are mostly 19th- and early-20th-century scholarly translations (the Loeb and Bohn Classical Libraries, Dryden's Plutarch, Shuckburgh's Cicero); the Christian works come predominantly from the Ante-Nicene Fathers (1885–1896) and Nicene and Post-Nicene Fathers (1886–1900) series. This shared Victorian prose register may soften, but should not erase, real differences in how pagan and Christian authors described character.
