These are the top texts in different languages I have gathered:
- Torah (Hebrew)
- Tao Te Ching (Chinese)
- Rig Veda (Sanskrit)
- Perfection of Wisdom (Tibetan)
- Quran (Arabic)
- New Testament (Greek)
- Tirukkural (Tamil)
- Metamorphoses? (Latin)
The Torah is probably the most important Hebrew book, the Quran for Arabic books, the Perfection of Wisdom is a very well known Tibetan one, the New Testament in Greek (though it also came shortly after in Latin, I am ignoring it for this question since it was already done in Greek).
Metamorphoses doesn't seem on par with these other texts. Is there anything in Latin on-par with these texts (that is also available online somewhere in text format)?
If you measure purely by most translated, the bible and tao te ching are at the top.
I would say Plotinus' Enneads but that is Greek lol.
Perhaps it is something in Christian Latin Literature. Or maybe Patrologia Latina, that looks way too big though compared to these books. Maybe Liturgical_books_of_the_Roman_Rite.
