Gathas

The Gathas are seventeen hymns, some 240 verses in all, composed in the archaic Old Avestan dialect and traditionally attributed to Zoroaster himself, embedded centuries later inside the larger liturgical Yasna as its sacred core. Unlike most surrounding Avestan material, the Gathas speak in a distinct first-person voice, closer to personal testimony and argument than to formal hymnody, addressing Ahura Mazda directly, questioning him, and pressing him for judgment against enemies and false priests.

Their central claim is a stark ethical dualism. At the beginning of existence, two primal spirits chose between asha, truth or right order, and druj, falsehood or chaos, and every subsequent being, divine or human, must make the same choice. Ahura Mazda, the wise lord, stands as the god of truth and creator of the material and spiritual worlds, opposed not by a rival creator but by the spirit of the Lie and the daevas, gods of the older Iranian religion whom the Gathas recast as demons deserving no worship. Zoroaster presents himself as Ahura Mazda's chosen prophet and as a poet-priest under threat from rival cult leaders and a hostile political order, appealing to a patron, Vishtaspa, for protection.

The Gathas ground this cosmic struggle in ordinary conduct: the recurring formula of good thoughts, good words, and good deeds treats ethics as the domain where the cosmic battle is actually fought and won, not an afterthought to ritual. Cattle husbandry and pastoral order function as a recurring image for this rightly ordered life, reflecting the hymns' setting among Iranian pastoralist communities. A final judgment, in which souls cross a bridge to reward or punishment according to their choices, appears here in nascent form, a concept that would later shape Second Temple Judaism, Christianity, and Islam through channels historians still debate.

Scholarly dating remains unusually uncertain for a text of this importance. Linguistic comparison with the Rigveda's Vedic Sanskrit, a closely related Indo-Iranian language, places the Gathas' language as early as 1200 BC, while an older Zoroastrian and classical tradition associates Zoroaster with the 6th century BC, closer to the Achaemenid period. Most specialists now favor the earlier, linguistically grounded dating, treating the traditional late date as a much later, retrospective placement rather than historical memory, though the question is not fully settled.
