Description:This coin was minted in Rome by moneyer L. Lucretius Trio in 74 BC. The obverse side features the infant Genius riding a dolphin. In ancient Roman religion, the Genius was the individual instance of a general divine nature that is present in every person, place, or thing. The rational powers and abilities of each and every human being were attributed to his soul, which was a genius. The Romans believed that the pleasantness of a place, the strength of an oath, an ability of a person was intrinsic to each yet were all attributable to genius. Lucretius may have chosen the Dolphin as a reference to his ancestor C. Lucretius Gallus who commanded the Roman fleet against Perseus of Macedon in 170 BC.
Neptune (shown on the reverse) with his trident, was the god of water and the sea. To the Greeks he was known as Poseidon. Neptune was the brother of Jupiter and Pluto, each of them presiding over one of the three realms of the universe, Heaven, Earth and the Underworld. Neptune's main temple in Rome was the Basilica Neptuni on the Campus Martius. It was dedicated by Agrippa in honour of his naval victory of Actium against the forces of Mark Antony and Cleopatra VII of Egypt in 31 BC.
