The History of Herodotus - Book 4: Melpomene (Unabridged)

One of the masterpieces of classical literature, the "Histories" describes how a small and quarrelsome band of Greek city states united to repel the might of the Persian empire. But while this epic struggle forms the core of his work, Herodotus' natural curiosity frequently gives rise to colorful digressions - a description of the natural wonders of Egypt; an account of European lake-dwellers; and far-fetched accounts of dog-headed men and gold-digging ants. With its kaleidoscopic blend of fact and legend, the "Histories" offers a compelling Greek view of the world of the fifth century BC.
BOOK 4: MELPOMENE: After the taking of Babylon, an expedition was led by Darius into Scythia. Asia abounding in men, and vast sums flowing into the treasury, the desire seized him to exact vengeance from the Scyths, who had once in days gone by invaded Media, defeated those who met them in the field, and so begun the quarrel.
