The Gāthās
Memorised for Two Millennia
- First attested
- 1323No manuscript containing the Gāthās survives from before the fourteenth century. The oldest are two Yasna manuscripts of 1323 — J2, now in the Bodleian, and K5, in Copenhagen — both copied by Mihrābān Kayhusraw, a priest of a Sīstān family working at Cambay in Gujarat at the invitation of the Parsi merchant Čāhil son of Sangan. Older Avestan manuscripts exist but do not carry the Gāthās: K7a, a Visperad, bears a date read as 1258 or 1288 and may itself be a later copy. The oldest physical witness to any Avestan text is earlier still and is likewise not a Gāthā — a single Aṣ̌əm Vohū prayer written in Sogdian script, from Dunhuang, dated about 800 CE (British Library Or. 8212/84). The Avestan alphabet is a Sasanian invention; before it the hymns were carried by memorised recitation, fixed word for word long before the redaction that finally wrote them down. The composition date of roughly 1700–1000 BCE is a linguistic argument, not a dated witness.
- Claimed
- the 580s BCEasserted by Zoroastrian chronology of the Sasanian period and after, preserved in the Middle Persian Bundahišn, which places Zarathustra 258 years before the death of Dārā son of Dārā — the end of the Achaemenid line under Alexander — and so about 588 BCE. Gherardo Gnoli argued the figure is historically sound; most Iranists reject it.
The claim runs about 1.9 thousand years ahead of the evidence.
The oldest surviving copies of the Gāthās are two Yasna manuscripts written in Gujarat in 1323 by the priest Mihrābān Kayhusraw — more than two millennia after the hymns were composed, and long after the Sasanian priests who rendered them into Pahlavi had, Humbach judged, ceased to understand Avestan properly.
The sacred hymns attributed to the prophet Zarathustra, forming the poetic foundation of Zoroastrian ethics and faith.
Seventeen hymns in Old Avestan, grouped by metre into five gāthās and set inside the Yasna liturgy at chapters 28–34, 43–51 and 53 — around the Yasna Haptaŋhāiti, which shares the archaic language but not the attribution to Zarathustra. Their date rests on that language alone, since the hymns name no datable king or place. Mary Boyce argued in 1975 for the second millennium BCE, her limits running from about 1700 to 1000; Prods Oktor Skjærvø and others place them about 1000. Zoroastrian tradition dated its prophet later — 258 years before Alexander, roughly 588 BCE, a reckoning the Bundahišn preserves. Priests still chant them in the daily Yasna. What English calls the Zend-Avesta is a misnomer: zand is the Pahlavi commentary, and the phrase came of misreading how Parsi priests labelled their manuscripts.
Light
Yasna 44 puts question after question straight to Ahura Mazdā — who fixed the path of sun and stars, who holds the earth below and the sky from falling. Yasna 30.2 tells each hearer to weigh the two choices himself, man by man.
Shadow
They are quarried for firsts — that Zarathustra invented monotheism, heaven and hell, the devil, the messiah. Skjærvø's 2011 translations show how much of that is later Sasanian systematisation. Whose words they are is itself disputed: Kellens reads ritual poetry, not autobiography.
