The mythologies of Greece and Rome are often confused. Blogger Roman compares the two, diving into the differences in the names of Roman and Greek gods and goddesses as well as what they represent.
Names and Appearance
The largest difference between Roman and Greek mythology lies in the gods. Greek gods and goddesses are named after people and are assigned genders; whereas in Roman mythology gods and goddesses were named after objects and characteristics and do not technically possess a gender (theoi.com). For example, Zeus, Hera, Athena, and Hermes all are common names in ancient Greek culture. Since Greek mythology predates Roman, the Romans borrowed liberally from the Greek gods. The gods of the Greeks and the Romans are presented and drawn differently. Greek gods were portrayed with heavy emphasis placed on their physical traits and attributes. Meanwhile Roman gods had a strong emphasis on characteristics such as morals and villainy and were not so clearly portrayed physically.
Worship and Beliefs
Another way that Greek and Roman gods differ lies in who they chose to worship. The Roman gods chose to hail Jupiter meanwhile the Greek gods chose to hail Zeus. In Greek mythology, morals played a vital and important role in the lives of the Greek gods. Greek mythology emphasizes the importance of good deeds and morals and learning important lessons through living life. The gods also teach mortals the lessons that they have learned. Every Greek myth included a teaching. Roman mythology was not so instructive. The Romans did not place as much stock in mythological teaching because of their strong belief in an afterlife. They believed they had time for redemption.
While researching this topic, I was astonished to read just how different the two mythological structures are, from how their respective gods look to how they are revered.
