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.
