Commentarius.
Commentary Production Platform

From annotation
to edition.

Commentarius takes classical texts from raw notes to press-quality commentary — morphological analysis, vocabulary, grammatical notes, and apparatus, typeset for print, the web, and the classroom.

P. Vergili Maronis Aeneis · I commentary
1Arma virumque canō, Trōiae quī prīmus ab ōrīs
Ītaliam fātō profugus Lāvīniaque vēnit
lītora, multum ille et terrīs iactātus et altō
4vī superum, saevae memorem Iūnōnis ob īram;

1arma virumque — the poem’s two subjects, war and the man, in emphatic first position; canō answers the Homeric incipit. A&G §598f

2fātō — ablative of cause with profugus: exiled by fate, not by guilt. A&G §404

3lītora — accusative of place to which without preposition, a poetic construction. A&G §428g

The workflow

One pipeline, from source text to the shelf

Every stage of commentary production lives in one workspace — so nothing is retyped, reformatted, or lost between drafts.

I · Prepare

Assemble your sources

Bring in texts and existing scholarship, and shape raw material into clean working notes.

II · Analyze

Write with the engine

Word-by-word morphology, syntax, and grammar, with every claim linked to its Allen & Greenough section so you can check it yourself.

III · Publish

Typeset every format

The same commentary, delivered as a LaTeX book, a DCC-style web edition, or a classroom handout.

The toolkit

The tools scholars actually reach for

The most-used tools on Commentarius are the ones that do the tedious work: building vocabulary lists tuned to what students don’t already know, formatting raw notes into clean commentary, and merging generations of scholarship into one working document. And wherever the platform makes a grammatical claim, it attaches the Allen & Greenough section — so you check it against the grammar book, not against our word.
