NEPTunus. -- This inscription accompanies the type of a temple of four columns, on a vary rare gold coin of the Roman Republic, struck by Cn. Domitius Ahenobarbus, son of L. Domitius, who in dared to resist Julius Caesar's passage of the Rubicon, but afterwards became reconciled to Antony and Octavian's party. The temple of Neptune indicated by the abbreviated word NEPT., shows maritime power, which Domitius retained under the Triumvirate, as commander of a fleet of Triremes, on the Italian coasts.
