In many ways Rome and Greece's religions were alike, but they were still different. Like the Greeks, Romans believed in multiple gods, and that all the gods controlled different parts of the world: the ocean, storms, blacksmith, marriage, and so forth.
Jupiter/Zeus
The chief of the gods was Jupiter, for the Romans. Jupiter's name is related to the name of the Greek god Zeus, and Jupiter is similar to Zeus in many ways. They are both sky gods who throw lightning bolts when they are angry.
Juno/Hera
Juno, in Roman religion, chief goddess and female counterpart of Jupiter, closely resembling the Greek Hera, with whom she was identified. With Jupiter and Minerva, she was a member of the Capitoline triad of deities traditionally introduced by the Etruscan kings.
Minerva/Athena
Minerva, in Roman religion, the goddess of handicrafts, the professions, the arts, and later, war; she was commonly identified with the Greek Athena. Some scholars believe that her cult was that of Athena introduced at Rome from Etruria. This reinforced by the fact that she was one of the Capitoline triad in association with Jupiter and Juno.
