This book deals with war between about 750 bc and ad 650. It concentrates on the classical cultures of Greece and Rome, although some of their enemies, peoples such as the Persians, Carthaginians, Germans, Huns, Arabs, and so on, get a look in. There are reasons beyond the author’s academic specialization for this focus. War was at the core of the classical cultures. Although, contrary to popular ideas, they were not always at war, and when they were they did not always seek open battle. The Greeks and Romans for long periods of time were generally successful in war, and war was never far from their minds.
