Note A — Chapter III · The Visit to Media.
Reading edition
The uncle here referred to was Mandane's brother. His name was Oyaxares. He was at this time a royal prince, the heir apparent to the throne. He figures very conspicuously in the subsequent portions of Xenophon's history as Astyages's successor on the throne. Herodotus does not mention him at all, but makes Cyrus himself the direct successor of Astyages.
