The first volume of The History by Herodotus sets out to preserve the memory of great human deeds and to examine the origins of the conflicts between the Hellenes and the barbarians. The narrative begins by recounting various accounts of early abductions of women, moving from Io and Europa to Medea and Helen, before shifting focus to the rise of Croesus, king of Lydia. Croesus subdues the Greek cities of Asia Minor and becomes renowned for his immense wealth, leading to a fateful encounter with the Athenian lawgiver Solon, who warns him that no living man may be called truly happy until he has reached a peaceful end. Following a devastating personal tragedy involving the death of his son Atys, Croesus seeks counsel from the Delphic Oracle regarding a war against the rising power of Persia.
Misinterpreting the ambiguous prophecy that he would destroy a great empire, Croesus marches across the Halys River into battle against Cyrus. After initial skirmishes, Cyrus successfully counterattacks and besieges Sardis, ultimately capturing Croesus and the city. While preparing to burn Croesus on a pyre, Cyrus listens as the captive king invokes Solon's name, which moves the Persian conqueror to extinguish the flames and spare his life.
Herodotus then traces the earlier history of the Median empire, detailing the rise of Deiokes, the subsequent invasions of the Scythians, and the eventual overthrow of Astyages by Cyrus, which establishes the supremacy of the Persians over Upper Asia. The narrative describes Persian customs, religious practices, and social structures before turning to the expansion of Cyrus's empire into Ionia and the subduction of the Ionian and Aiolian cities. Finally, the account follows Cyrus in his campaigns against the Assyrians, culminating in the ingenious capture of the great city of Babylon by diverting the waters of the Euphrates river, thus securing Persian hegemony across the region.
