The Behistun Inscription says that Paišiyâuvâdâ was the place where the Magian named Gaumâta raised a rebellion against the Achaemenid king Cambyses, who was in Egypt or Syria. This is remarkable, because other rebels mentioned in the inscription are never introduced with an indication of the place of their revolt.
A possible explanation is that in the Zoroastrian cosmology, the earth was created by Ahuramazda with a perfect, level surface; mountains were believed to be the result of the countercreation by the supreme god's opponent, Angra Mainyu ("the hostile spirit").note[Greater Bundahišn 6C1.] The fact that Gaumâta started his revolt on a mountain was, in this view, proof of his wickedness, and something worth recording.
