Jerome

Ancient texts, opened to modern readers

Jerome is a tool for reading and studying ancient texts. It brings Greek and Latin works together with translations, citation-aware navigation, search, dictionaries, grammatical analysis, statistics, and intertextual connections.

Jerome is built for general readers who want to enter the classical and patristic worlds, as well as for students and scholars who need more powerful ways to investigate the texts.

Purpose

Why Jerome exists

Ancient texts are more accessible than ever, but they remain scattered across repositories, difficult to navigate, inconsistently catalogued, and often separated from the tools needed to understand them.

Jerome aims to bring those materials into one coherent reading environment. A reader should be able to open a work, compare the original with a translation, examine an unfamiliar word, search related passages, follow a quotation into another author, and return to the text without losing the thread of the reading.

The project takes inspiration from resources such as Perseus and the Thesaurus Linguae Graecae while asking what a multilingual ancient-text platform should look like if designed in the 2020s: accessible on modern devices, built around search and structured data, open to new languages, and useful beyond a narrow institutional audience.

Origins

The history of Jerome

The first idea for Jerome emerged during the COVID-19 pandemic in 2020: a multilingual platform that could bring ancient texts and their translations together.

Development began in late 2022. The first usable version was completed in January 2023, and the project has continued to expand since then in corpus size, reading tools, search capabilities, and scholarly functions.

Why the name “Jerome”?

The name evokes Saint Jerome, the translator of the Bible and one of the great mediators between languages and literary traditions.

Jerome is multilingual at its core. Its purpose is not merely to store ancient texts, but to help texts written in Greek and Latin reach readers who approach them through Spanish and, eventually, other modern languages.

In practice

What you can do in Jerome

Read original texts

Read classical, biblical, and patristic works in Greek and Latin with structured navigation based on their traditional citation systems.

Compare translations and versions

Where compatible versions are available, Jerome can display an original text beside a translation or another textual version.

Study individual words

Where linguistic data are available, select a word to see its lemma, grammatical analysis, and dictionary information.

Search the corpus

Search for words, exact forms, phrases, authors, works, and passages. Advanced tools support lemma, morphology, proximity, metadata, multilingual, and corpus-specific searches.

Advanced search across large Latin corpora is one of Jerome’s central areas of development.

Discover relationships between texts

Jerome presents quotations, references, verbal parallels, allusions, echoes, and other relationships among passages. Some come from source material or editorial research; others begin as computational suggestions and require further assessment.

Save personal research

Access

Free texts, paid computation

Jerome is committed to keeping the underlying ancient texts freely readable.

Subscriptions are charged for the computation and continuing infrastructure placed on top of those texts: larger search capacity, dictionaries, morphology, advanced analysis, statistics, intertexts, exports, and future research tools.

In other words, Jerome does not intend to place a tollbooth in front of Greek and Latin literature. Paid plans support the systems that make a large corpus easier to read, search, and study.

Jerome is deliberately priced with the circumstances of students—particularly Latin American students—in mind.

Provenance

Texts, sources, and translations

Jerome has used openly available source files from projects including Perseus and Corpus Corporum, together with other classical, biblical, and patristic collections.

The ancient works themselves belong to humanity’s common inheritance, but particular digital transcriptions, editions, translations, annotations, and metadata may have their own source and licensing conditions. Jerome seeks to preserve and display provenance wherever it is available.

Most Spanish translations currently found in Jerome were generated with Google Gemini and are prominently identified with version names such as Spanish-Gemini. They are intended to make difficult texts approachable, but they remain machine-generated translations and can contain errors.

Most biblical material currently uses a Reina-Valera translation. The specific version and source are identified in the Reader where available.

Corpus

How the corpus is processed

Texts arrive in many different formats and with inconsistent names, structures, spellings, and citation systems. Jerome processes them into a shared corpus structure while preserving their individual versions and provenance.

From this text layer, Jerome builds the derived systems used for:

  • structured reading and navigation;
  • original-and-translation alignment;
  • textual and lemma search;
  • morphological analysis;
  • dictionary connections;
  • statistics;
  • intertextual discovery;
  • citation and export tools.

These analytical layers are kept conceptually separate from the underlying text. A machine-generated lemma, alignment, or intertextual suggestion should not silently become part of the ancient work itself.

Caution

Editorial standards and limitations

Jerome is a research and reading aid, not a substitute for an appropriate critical edition.

Texts and metadata may contain transcription errors, OCR problems, imperfect segmentation, disputed attributions, or incomplete source information. Machine-generated translations, morphological analyses, alignments, statistics, and intertextual suggestions can also be wrong.

Users should verify important quotations and scholarly conclusions against the identified source or a suitable critical edition.

Jerome tries to distinguish among:

  • source text and derived analysis;
  • human editorial information and automated results;
  • explicit citations and probable parallels;
  • reviewed material and experimental suggestions;
  • human translations and machine-generated translations.

All current editorial work is carried out by the project’s founder and maintainer. Jerome is therefore necessarily incomplete, but corrections can be reviewed consistently rather than passing through an anonymous process.

Outlook

Independence and intellectual outlook

Jerome is an independent personal project based in Argentina. It has no formal affiliation with a university, church, publisher, or research institution.

Its founder is Catholic, and the project is informed by the conviction—shared by generations of monks, teachers, and scholars—that classical, biblical, and patristic texts remain valuable and can strengthen the intellectual and religious lives of their readers.

Jerome itself is not designed as a catechism or as a mechanism for imposing religious conclusions. Readers are given access to texts and tools with which to study them.

Who maintains Jerome?

Jerome is created and maintained by Andrés Baldrich, a PhD candidate in Patristic Studies at the Universidad Católica de Cuyo in San Juan, Argentina.

Jerome is currently a one-person project. Andrés is responsible for its development, corpus processing, editorial decisions, translations workflow, infrastructure, and user support.

Special thanks are due to Leonel Di Camillo for his support in product design and in helping Jerome reach its intended users.
