to Cyrus's descent, education, and stay at the court of his maternal grandfather, the Median dynast Astyages. Scholars have noted that Xenophon's description of pre-imperial Persian education is unusual and appears to be based upon the traditions of Sparta: the subject of Xenophon's other work the Constitution of the Lacedaemonians. Books Two to Seven Books two to seven cover Cyrus's life as a Median vassal on his path to establishing the world's largest empire. In these books, Cyrus is upheld as an example of classical virtue, but also uses what are now known as Machiavellian tactics. He proves a faithful vassal to the Medes, initially acting as a general to defend them from the more powerful and assertive Babylonian empire. He does so by cultivating alliances with nations such as the Chaldeans, Hyrcanians, Cadusians, Saka, and Susians. The remaining allies of Babylon include many nations of Asia Minor, as well as a corps of Egyptian infantry. Croesus of Lydia acts as general in the two powers' final field battle. Cyrus then returns with an increasingly international army to conquer Babylon. He is able to avoid a long siege by deflecting the course of the river through it, then sending soldiers in over the dry bed during a festival night. The claim that Babylon was conquered on the night of a festival by diverting the Euphrates River from its channel is also made by Herodotus (1.191). Book Eight Book eight is a sketch of Cyrus' kingship and his views of monarchy. The last section of this book (8.8) also describes the rapid collapse of Cyrus's empire after he died. It has been speculated that this section was written by a later author. Alternatively, it may symbolize Xenophon's theoretical inconsistency concerning his conception of an ideal ruler, or show that Xenophon did not mean to describe an ideal ruler in any simple way. It may also intend to display, rather than undermine, Cyrus's strength as a leader. Related characters of questionable historical truth appear in the narrative as well. For example, the romance of Abradatas and Pantheia forms much of the narrative's latter half (v.1.3, vi.1.31ff, vi.4.2ff, vii.3.2ff). Reception In classical antiquity, the Cyropaedia was considered the masterpiece of a widely respected and studied author. Polybius, Cicero, Tacitus, Dionysius of Halicarnassus, Quintilian, Aulus Gellius and Longinus thought highly of Xenophon and his work. Classical authors believed that he composed the Cyropaedia in
