How did the city-state of Athens defeat the invaders from Persia, the first world empire, on the plain of Marathon in 490 BCE? Scholars skeptical of our earliest surviving source, Herodotus, have produced one ingenious theory after another. In this stimulating new book, bound to provoke controversy, Peter Krentz argues that Herodotus was right after all. Beginning his analysis with the Athenians' first formal contact with the Persians in 507 BCE, Krentz weaves together ancient evidence with travellers' descriptions, archaeological discoveries, geological surveys, and the experiences of modern reenactors and soldiers to tell his story. Krentz argues that before Marathon the Athenian army fought in a much less organized way than the standard view of the hoplite phalanx suggests: as an irregularly armed mob rather than a disciplined formation of identically equipped infantry. At Marathon the Athenians equipped all their fighters, including archers and horsemen, as hoplites for the first time. Because their equipment weighed only half as much as is usually thought, the Athenians and their Plataean allies could charge almost a mile at a run, as Herodotus says they did. Krentz improves on Herodotus' account by showing why the Athenians wanted to do such a risky thing.

Peter Krentz is W.R. Grey Professor of Classics and History, Davidson College, where he has taught Greek and Roman history since 1979.

"It is hard to imagine that Krentz's account of the events on that sweltering day can be improved on: the maddeningly elusive topography of the Marathon plain, in particular, has never been better treated."--Peter Thonemann, "The Times Literary Supplement"--Peter Thonemann "The Times Literary Supplement "
