During this period, Quintus Curtius was known not as a historian but as a minter (triumvir monetalis) in the Roman Republic. The Curtia gens was an ancient Roman family, whose name is associated with the legend of the famous Roman horseman who threw himself into a chasm in the Forum for the sake of his country. Coinage: Quintus Curtius, together with Marcus Junius Silanus, minted silver denarius coins, which featured the following motifs: Obverse: Helmeted head of Roma facing right, behind him an "X" mark (value mark), next to it the inscription "Q•CVRT". Reverse: Jupiter galloping right in a quadriga, throwing thunderbolts and holding a scepter, above him a lituus (a curved priestly staff), below the inscriptions "M•SILA" and "ROMA". Origin: The Curtia gens was probably of plebeian origin and was associated with the Sabine ethnic group. The name comes from the Latin word "curtus", which means "truncated" or "incomplete". The motifs on the coins do not directly refer to the legendary self-sacrificing Roman horseman, but are nevertheless associated with him through the use of the name. These coins have survived to this day and have appeared at several auctions, and are sought after by collectors due to their rarity.
