The History of Herodotus - Book 9: Calliope (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 9: CALLIOPE: Mardonius, when Alexander upon his return made known to him the answer of the Athenians, forthwith broke up from Thessaly, and led his army with all speed against Athens; forcing the several nations through whose land he passed to furnish him with additional troops.
