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.
