Coins were the most deliberate of all symbols of public communal identities, yet the Roman historian will look in vain for any good introduction to, or systematic treatment of, the subject. Sixteen leading international scholars have sought to address this need by producing this authoritative collection of essays, which ranges over the whole Roman world from Britain to Egypt, from 200 BC to AD 300. The subject is approached through surveys of the broad geographical and chronological structure of the evidence, through chapters which focus on ways of expressing identity, and through regional studies which place the numismatic evidence in local context.
