## sources
### perseus digital library (16,004 pairs)
aligned passages from 168 works by 28 authors in the [perseus digital library](http://www.perseus.tufts.edu/), covering classical greek and latin literature.
authors include homer, thucydides, plutarch, cicero, livy, ovid, tacitus, aeschylus, pindar, hippocrates, lucian, julius caesar, pliny the elder, and others.
texts range from 5th century BCE (thucydides, aeschylus) through late antiquity (augustine, bede).
### bible (54,377 pairs)
verse-level alignments from:
- **greek**: SBLGNT (new testament) + swete's septuagint (old testament)
- **latin**: clementine vulgate
- **hebrew**: leningrad codex (old testament only, 14,712 verses)
- **english**: king james version
covers 39 books across old and new testaments. each verse produces separate greek-english, latin-english, and (where available) hebrew-english pairs.
## preprocessing
- pairs with either side under 20 characters were filtered (47 rows removed: roman numeral headings, single-word fragments)
- no deduplication applied (some bible verses appear in multiple books as cross-references)
- perseus texts preserve original polytonic greek diacriticals
- bible greek preserves editorial marks from SBLGNT
## intended use
- training and evaluating cross-lingual embedding models
- ancient language retrieval and search
- machine translation for classical languages
- cross-lingual alignment research
