An ancient plated copy of an excessively rare and desirable type. From a private European collection. According to Dio Cassius, following success in naval battles against Octavian, Sextus Pompey came to be known as 'Son of Neptune' as reflected in the obverse legend NEPTVNI and the trident symbol. The reverse legend names Quintus Nasidius, an admiral under Pompey Magnus and then Sextus. Realising the futility of the Pompeian cause, Nasidius eventually defected to the camp of Marc Antony, and fought under him at the Battle of Actium, after which point he disappears from the historical record.
