This denarius of Decimus Junius Brutus Albinus shows on the obverse Mars, the god of war, a traditional Roman coin design. On the reverse are two shields and two Celtic trumpets between the inscription ALBIN. BRVTI. F for the moneyer.
Decimus Brutus was a loyal supporter of Gaius Julius Caesar. He had served in Caesar's army in the Gallic wars (58-50 BC), and during the subsequent Civil War (49-45 BC) continued to fight at his commander's side.
In the year 44 BC, however, Brutus reversed his opinion, joined the conspiracy against Caesar and became one of his assassins. The reason was Brutus' categorical belief in the values of the Republic. He suspected Caesar of planing to become sole ruler of Rome, an abhorrent vision for every republican Roman.
