The ancient Romans were highly ecumenical, eagerly assimilating deities and mythology from surrounding Indo-European cultures into their own pantheon and mythology. Listed below are important Roman deity names gathered from Latin, Italian, and Greek sources.
Below is the English spelling of the Interpretazione roma. These are what is called Dodecatheon Olympionicae Deorum Graecorum (twelve Greek Olympian deieties) who were absorbed and adopted into the religious mileu of the Roman pantheon.
This list of Roman and Italian deities includes old Roman Goddesses/Gods as well as the Roman and Italian deities.
The Roman and Italian deities--the Dii Consentes below are the Roman equivalent of the Greek Olympian deities. The Romans frequently venerated the deities belonging to other groups of people around them. (See Bellona)
The Romans borrowed quite a lot of cultural and religious ideas from the Greeks. There is no single defining canonical list from the Greeks of the twelve original Olympian Gods. Likewise, thirteen or fourteen Greek Goddesses and Gods had Roman counterparts.
The term interpretatio romana derives from Tacitus' Germania, ch. 43, and literally means "according to the Roman interpretation."
The practice of interpretatio romana is especially well known through Caesar's De Bello Gallica, where he describes the Gods of the Gauls in terms of their similarity to the Roman pantheon. Caesar wrote about the Celtic Gauls:
"Among the gods, they most worship Mercury. There are numerous images of him; they declare him the inventor of all arts, the guide for every road and journey, and they deem him to have the greatest influence for all money-making and traffic. After him they set Apollo, Mars, Jupiter, and Minerva. Of all these deities they have almost the same idea as all other nations: Apollo drives away diseases, Minerva supplies the first principles of arts and crafts, Jupiter holds the empire of heaven, Mars controls wars. ...The Gauls affirm that they are all descended form a common father, Dis, and say that this is the tradition of the Druids"This practice was not unique to the Romans. Many history teachers have similarly compared and contrasted the mythologies of sundry groups of peoples.
