Critical Editions: Leonine, Marietti, Decker & Corpus Thomisticum

Philological Provenance & Paragraph Synchronization in geometor-aquinas

To ensure complete philological reliability and 1-to-1 cross-referencing with twentieth-century Thomistic scholarship (especially Fr. Peter Hoenen, S.J.’s De Noetica Geometriae, 1954), geometor-aquinas preserves the exact diplomatic Latin text and canonical numbering of three landmark editorial traditions:

  1. The Leonine Edition (*Editio Leonina*, Rome, 1882–present) Commissioned by Pope Leo XIII in 1879, the Leonine Commission established the critical Latin text of the Posterior Analytics (Tom. I, 1882; Tom. I* 2, ed. R.-A. Gauthier, 1989), Physics (Tom. II, 1884), De Caelo (Tom. III, 1886), Summa Theologiae Prima Pars (Tom. IV–V, 1888–1889), De Veritate (Tom. XXII, 1970–1976), De Anima (Tom. XLV.1, 1984), and Super Boetium De Trinitate (Tom. L, 1992).

  2. The Marietti Taurini Manual Editions (Pirotta, Cathala–Spiazzi, Maggiòlo, Bazzi) Throughout the twentieth century, scholars citing Aquinas’s Aristotelian commentaries referenced the sequential paragraph numbers introduced by the Dominican editors of Casa Editrice Marietti (Turin): - Angelo Maria Pirotta, O.P. (In Aristotelis Librum De Anima Commentarium, 1925 / 1936): sequential paragraphs #1–#846 (e.g., Hoenen’s citations of Pirotta #170, #770–777, and #791 in Pars III). - Marie-Raymond Cathala, O.P. & Raimondo M. Spiazzi, O.P. (In duodecim libros Metaphysicorum Aristotelis expositio, 1915 / 1950): sequential paragraphs #1–#2663 (e.g., Hoenen’s citations of Cathala #890, #1496, #1805–1806, and #1894 in Pars V).

  3. Bruno Decker’s Edition of Vatican Autograph *Vat. lat. 9850* (1959) Because Aquinas’s personal autograph manuscript of Super Boetium De Trinitate survives in the Vatican Library (Codex Vaticanus Latinus 9850), Bruno Decker’s 1959 Leiden critical edition (together with the 1992 Leonine edition) restored Aquinas’s exact autograph wording in Question 5, Article 3—crucially distinguishing separatio from abstractio.

  4. Index Thomisticus & Corpus Thomisticum Initiated by Fr. Roberto Busa, S.J. in 1949 and curated online by Prof. Enrique Alarcón at the University of Navarra (Corpus Thomisticum), the public-domain diplomatic Latin corpus preserves the exact paragraph boundaries of the Leonine and Marietti editions. Every paragraph in resources/aquinas/sources/pars_1..5_latin.json records its ct_id, scholastic title, Marietti number (where applicable), and SHA-256 cryptographic digest in resources/aquinas/sources_manifest.json.
