Greek vs. Roman Gods – What are the Differences?

The Greek and Roman mythologies were among the most influential of ancient times. The Roman mythology borrowed most of Greek mythology wholesale, which is why there’s a Roman counterpart for almost every Greek deity or hero. However, the Roman deities had their own identities and were distinctly Roman.

Apart from their names, there were some differences in the roles of the Roman counterparts of the Greek gods. Here are some of the most well-known:

Roman Name: Apollo

Similarities: Apollo did not have a direct Roman equivalent, so the Greek god sufficed for both mythologies with the same traits. He is one of the few deities that didn’t have a name change.

Differences: Since Roman mythology mainly derived from the Greeks, this god had no changes during Romanization. They were the same deity.

Artemis – Diana

Roman Name: Diana

Role: These female deities were the goddesses of hunting and the wild.

Similarities: Artemis and Diana were virgin goddesses who favored the company of animals and forest creatures over the company of men. They lived in the woods, followed by deer and dogs. Most of their depictions show them in the same manner, and they share most of their myths.

Differences: The origin of Diana might not totally derive from Artemis since there was a deity of the forest known by the same name before the Roman civilization.

Similarities: Both gods share most of their myths and had several associations with war conflicts. Ares and Mars were sons of Zeus/Jupiter and Hera/Juno respectively. People worshipped them for their favor in military activities.

Roman Name: Mercury

Role: Hermes and Mercury were the heralds and messengers of the gods of their cultures.

Persephone – Proserpine

Greek Name: Persephone

Roman Name: Proserpine

Role: Persephone and Proserpine are goddesses of the underworld in Greek and Roman mythologies.

Differences: There is little to no difference between these two goddesses. However, Proserpine is seen as being more responsible for the four seasons of the year alongside her mother, Ceres, in Roman mythology. Proserpine was also the goddess of springtime. 

Differences Between Greek and Roman Gods and Goddesses

Apart from the individual differences of the Greek and Roman deities, there are some important distinctions that separate these two similar mythologies. These include:

  1. Age – Greek mythology is older than Roman mythology, predating it by at least 1000  years. By the time the Roman civilization came into existence, Homer’s Iliad and Odyssey was seven centuries old. As a result, Greek mythology, beliefs and values were already firmly established and developed. The fledging Roman civilization was able to borrow much of Greek mythology and then added a truly Roman flavor to create distinct characters that represented the values, beliefs and ideals of the Romans.
  2. Physical Appearance – There’s also notable physical differences between the deities and heroes of the two mythologies. For the Greeks, the appearance and traits of their gods and goddesses was of paramount importance and this would be included in the descriptions in the myths. This isn’t the case with Roman gods, whose appearance and characteristics aren’t emphasized in the myths.
  3. Names – This is an obvious difference. The Roman gods all took on different names to their Greek counterparts.
  4. Written Records – Much of the depictions of Greek mythology comes from Homer’s two epic works – The Iliad and The Odyssey. These two works detail the Trojan War, and many of the famous related myths. For Romans, one of the defining works is Virgil’s Aeneid, which details how Aeneus of Troy traveled to Italy, became the ancestor of the Romans and established there. The Roman gods and goddesses are described throughout in this work.

In Brief

Roman and Greek mythology had many things in common, but these ancient civilizations managed to stand out on their own. Many aspects of modern Western culture have been influenced by these gods and goddesses. Thousands of years later, they are still significant in our world.
