Bellona was an ancient Roman goddess of war. Her main attribute is the military helmet worn on her head; she often holds a sword, spear, or shield, and brandishes a torch or whip as she rides into battle in a four-horse chariot. She had many temples throughout the Roman Empire. She is known for her temple outside of Rome being the official decision making centre in regards to war and for her bloodlust and madness in battle. Her iconography was extended by painters and sculptors following the Renaissance.

Eris is the Greek goddess of strife and discord. Her Roman equivalent is Discordia, which means the same. Eris's Greek opposite is Harmonia, whose Roman counterpart is Concordia, though she is also described as opposing Nike, counterpart of the Roman Victoria. Homer equated her with the war-goddess Enyo, whose Roman counterpart is Bellona. The dwarf planet Eris is named after the goddess.
