The Romans were renowned for adopting other idea from other cultures. Foreign kingdoms had influenced the Roman way of thinking, particularly the Etruscan and Greek cultures. The Romans had adopted the Greek philosophy, art and literature.
Myths were no exception. The Roman had modelled their gods from the Greeks.
The following lists were made as quick reference for those who wished to compare the Roman and Greek names of gods and goddesses.
This is by no mean a very exhaustive list of Roman deities and their Greek equivalents. Some deities, like Apollo was a completely Greek import. There was no Roman equivalent of Apollo, but the Roman writers had adopted Apollo as their very own. Most of the Titans had no Roman names, with the exception of Cronus and Rhea. Where there were no Roman names for the gods, the Greek names had been used and left unchanged.
Notice that I have links on some of Greek deities listed below. If the information and myths were the same in both Greek and Roman deities then it would be best to search for the article in Greek gods.
