Kalila wa-Dimna descends from Borzuya's lost mid-6th-century (c. 550–570 CE) Pahlavi Panchatantra, which Ibn al-Muqaffa rendered into Arabic in the 8th century

The fable collection known in Arabic as Kalīla wa-Dimna reaches the Islamic and European worlds through a chain of translations, each link of which is now partly lost:

1. A Sanskrit Panchatantra (the version Borzuya worked from — itself not preserved).
2. Borzuya's Pahlavi (Middle Persian) translation, made in the mid-6th century (tertiary sources place it anywhere from c. 550 to c. 570 CE) at the Sasanian court — also lost.
3. An Arabic translation made in the 8th century by Ibn al-Muqaffaʿ, Kalīla wa-Dimna, which survives and becomes the ancestor of the collection's onward spread.

From the Arabic, the fables radiated into Syriac, Greek, New Persian, and eventually most European languages, making this one of the most widely translated works in world literature. The intermediary Pahlavi stage means the surviving Arabic is a translation of a (lost) translation of a (lost) original — which is exactly why the story of how Borzuya carried the text out of India (claim-borzuya-immortality-herb-was-really-a-book) matters to how the text came down at all. The capture places the Pahlavi work at the Sasanian learning center of Gondishapur, the academy that had been drawing in Greek, Indian, and exiled Neoplatonist scholarship since the 3rd century CE — though the cited "Borzuya" article itself marks his Gondishapur connection only as "possibly."

2026-07-27 update: the chain and both round dates now clear Tier 1–2. A 2020 peer-reviewed article from the ERC-funded AnonymClassic project (Freie Universität Berlin) states the chain and dates directly: "the first (lost) redaction to Middle Persian (i.e., Pahlavi, c. 550 CE); the translation into Syriac … and Arabic (c. 750 CE)." The Institute of Ismaili Studies independently corroborates and adds the lost Pahlavi text's own title, Karirak ud Damanak — distinct from the "Kalila wa-Dimna" title that only attaches at the Arabic stage — and dates Ibn al-Muqaffaʿ's death, and so his Arabic recension, to "c. 757 CE." Both sources were fetched directly, not reconstructed from a search summary, so both clear sources.md's quote-provenance floor as well as its Tier 1–2 sourcing floor. What they do not give is the specific "570" endpoint in this note's own title — the Tier 1 source rounds to a bare "c. 550 CE" and neither Tier 2 source narrows past "6th century" / "time of Khosrow I (r. 531–79)." A related nuance — whether de Blois and current scholarship treat Borzuya's authorship as settled or merely plausible — is its own claim, not folded in here: claim-de-blois-borzuya-mission-historically-plausible-not-proven. A minority dissent on the chain's Indian origin exists too: see claim-al-yamani-disputed-kalila-wa-dimnas-indian-origin. And the chain's lost Pahlavi and surviving Arabic stages are not the only descendants — see claim-two-syriac-translations-of-kalila-wa-dimna-survive-independently.

Why this note is budding, not evergreen, and still partly flagged. The transmission chain itself and the two round dates are now Tier 1–2 confirmed above. The specific "570" endpoint is not — it remains [unverified-quant — needs primary], most likely resolved only by François de Blois's 1990 monograph directly.
