Hippocampus (mythology) Poseidon (or Roman Neptune) often drives a sea-chariot drawn by hippocampi. Thus hippocampi sport with this god in both ancient depictions and much more modern ones, such as in the waters of the 18th-century Trevi Fountain in Rome surveyed by Neptune from his niche above. The appearance of hippocampi in both freshwater and saltwater is counter-intuitive to a modern audience, though not to an ancient one. The Greek picture of the natural hydrological cycle did not take into account the condensation of atmospheric water as rain to replenish the water table, but imagined the waters of the sea oozing back
Roman mythology counterparts. Rome's early myths and legends also have a dynamic relationship with Etruscan religion, less documented than that of the Greeks. While Roman mythology may lack a body of divine narratives as extensive as that found in Greek literature, Romulus and Remus suckling the she-wolf is as famous as any image from Greek mythology except for the Trojan Horse. Because Latin literature was more widely known in Europe throughout the Middle Ages and into the Renaissance, the interpretations of Greek myths by the Romans often had a greater influence on narrative and pictorial representations of "classical mythology" than Greek sources.
