Quirinus said to be the same as Romulus
Brelich's argument for split deification
Historian Angelo Brelich argued that Quirinus and Romulus were originally the same divine entity which was split into a founder hero and a god when Roman religion became demythicised. To support this, he points to the association of both Romulus and Quirinus with the grain spelt, through the Fornacalia or Stultorum Feriae, according to Ovid's Fasti.The last day of the festival is called the Quirinalia and corresponds with the traditional day of Romulus' death. On that day, the Romans would toast spelt as an offering to the goddess Fornax. In one version of the legend of Romulus' death cited by Plutarch, he was killed and cut into pieces by the nobles and each of them took a part of his body home and buried it on their land.Brelich claimed this pattern – a festival involving a staple crop, a god, and a tale of a slain founding hero whose body parts are buried in the soil – is a recognized mytheme that arises when such a split takes place in a culture's mythology (see Dema deity archetype). The possible presence of the Flamen Quirinalis at the festival of Acca Larentia would corroborate this thesis, given the fact that Romulus is a stepson of hers, and one of the original twelve arval brethren (Fratres Arvales).
