What did Greek and Roman goddesses do?
The Greek and Roman gods and goddesses represented many things. They were figureheads that were worshiped to bring peace, justice, hope, food and etc.
The 'Roman Names' were worshiped and known to the Romans before the Greek; when the Greek people were conquered, their gods and goddesses were incorporated into the Roman gods and goddesses; so it is that it is near impossible to now tell the difference between the two. That, by the way, was a common practice of the Romans, adopting the gods and goddesses of the people they conquered/ruled.
Greek gods were kinder, and less about war. Roman gods were about honor, strength and discipline. Also, the Greek gods were the original ones. Later, the Romans came and borrowed the Greek gods(cultural borrowing) but put different names. For example: Hera (Greek)is Juno(Roman), Zeus is Jupiter, Hades is Pluto, etc. ZL
Most of the Roman and Greek Gods and Goddesses share enough attributes to be considered roughly the same, but with a different name - Latin for the Roman, Greek for the Greek. Some of the Roman and Greek gods and goddesses for example, Apollo, have only the one name for both the Romans and the Greeks Example- Zeus> Jupiter Poseidon>Neptune Hera> Juno Aphrodite>Venus
