She is also identified as his sister, and daughter of Zeus and Hera, in a role closely resembling that of Eris; with Homer (in particular) representing the two as the same goddess.
In earlier times she was called Duellona, the name being derived from a more ancient word for "war".
She is believed to be one of the numinous gods of the Romans (without a particular mythology and possibly of Etruscan origin), and is supposed by many to have been the Romans' original war deity, predating the identification of Mars with Ares.
Bellona is the Roman Goddess of War, closely associated with Mars, the Roman War-God.
Ma, or Ma-Bellona is a Goddess of Cappadocian origin (a region in Anatolia, modern Turkey) who was identified with the Italian Bellona, and for whom a seperate temple was built in Rome.
She is described as "dark Bellona, with bloody hand", by Publius Statius (court poet to the Emperor Diocletian).
