mural: The death of Gav-aēvō.dātā/Gawiewdad, the primordial bovine. In the
Bundahishn, a Zoroastrian account of creation finished in the 11th or 12th century CE,
Ohrmazd and
Ahriman already co-exist at the beginning of time, but Ahriman is not immediately aware of Ohrmazd. During the first 3000 years (the first cosmic age), Ahriman espied the light of Ormuzd but "seeing valor and supremacy superior to his own, he fled back to the darkness and fashioned many demons — a creation destructive and ready for battle". Ohrmazd, being omniscient, knows of the inevitability of the attack and creates fire (
Adur) "with his thought", with which the universe would subsequently be suffused with goodness (life). Upon being attacked, Ohrmazd recites the
Ahunawar invocation, thus revealing His ultimate victory to Ahriman, who then falls back confounded for another 3000 years. Towards the end of the second cosmic age (the second 3000 years), Ahriman, who until then has resisted the exhortations of his demons, is roused from his impotence by Jahi's beguiling devices, who promises to destroy the creatures of Ohrmazd. Incited, Ahriman defiles her with a kiss, and from this act Jahi is thenceforth afflicted with menstruation. Jahi is appointed by Ahriman for the defilement of females, and it is this defilement that causes women to have their
menses. Jahi's gaze is said to be powerful enough to kill. ==Notes==
