to convince the other nobles. To decide who would become the monarch, six of them decided on a test, with Otanes abstaining, as he had no interest in being king. They were to gather outside the palace, mounted on their horses at sunrise, and the man whose horse neighed first in recognition of the rising sun would become king. According to Herodotus, Darius had a slave, Oebares, who rubbed his hand over the genitals of a mare that Darius's horse favored. When the six gathered, Oebares placed his hands beside the nostrils of Darius' horse, who became excited at the scent and neighed. This was followed by lightning and thunder, leading the others to dismount and kneel before Darius in recognition of his apparent divine providence. In this account, Darius himself claimed that he achieved the throne not through fraud, but cunning, even erecting a statue of himself mounted on his neighing horse with the inscription: "Darius, son of Hystaspes, obtained the sovereignty of Persia by the sagacity of his horse and the ingenious contrivance of Oebares, his groom." According to the accounts of Greek historians, Cambyses II had left Patizeithes in charge of the kingdom when he headed for Egypt. He later sent Prexaspes to murder Bardiya. After the killing, Patizeithes put his brother Gaumata, a Magian who resembled Bardiya, on the throne and declared him the Great King. Otanes discovered that Gaumata was an impostor, and along with six other Iranian nobles including Darius, created a plan to oust the pseudo-Bardiya. After killing the impostor along with his brother Patizeithes and other Magians, Darius was crowned king the following morning. The details regarding Darius' rise to power is generally acknowledged as forgery and was in reality used as a concealment of his overthrow and murder of Cyrus' rightful successor, Bardiya. To legitimize his rule, Darius had a common origin fabricated between himself and Cyrus by designating Achaemenes as the eponymous founder of their dynasty. In reality, Darius was not from the same house as Cyrus and his forebears, the rulers of Anshan. Early reign Early revolts Following his coronation at Pasargadae, Darius moved to Ecbatana. He soon learned that support for Bardiya was strong, and revolts in Elam and Babylonia had broken out. Darius ended the Elamite revolt when the revolutionary leader Aschina was captured and executed in Susa. After three months the revolt in Babylonia had ended.
