In Zoroastrian creation myth, what is the name of the primordial ox?

In Zoroastrian creation myth, the primordial ox is called Gavaevodata. The Avestan name is often translated as “sole-created” or “uniquely created bovine,” and English references commonly call the figure the primordial ox, primordial bull, or primordial bovine.

Gavaevodata is one of Ahura Mazda’s six primordial material creations and is described in later Zoroastrian tradition as the ancestor of beneficial animal life. The creation myth places the ox alongside Gayomard, the primordial human. Both are eventually killed through the destructive activity of Angra Mainyu and his forces, but their deaths become sources of renewed creation rather than simple endings.

According to later accounts, the ox’s body, marrow, organs, and seed help repopulate the world with animals. Its soul, known as Geush Urvan, becomes associated with the soul of cattle. This connection helps explain the special religious importance of cattle and the cow in Zoroastrian thought.

The surviving Avesta mentions Gavaevodata by name only rarely; much of the detailed creation story comes from later Middle Persian works such as the Bundahishn. Gayomard, one of the wrong options, is the primordial man—not the ox.
