One theory of this tradition concerns the emergence of two mythical figures from a single, earlier legend. Romulus is a founding hero, Quirinus may have been a god of the harvest, and the Fornacalia was a festival celebrating a staple crop (spelt). Through the traditional dates from the tales and the festivals, they are each associated with one another. A legend of the murder of such a founding hero, the burying of the hero's body in the fields (found in some accounts), and a festival associated with that hero, a god of the harvest, and a food staple is a pattern recognized by anthropologists. Called a ""dema" archetype", this pattern suggests that in a prior tradition, the god and the hero were in fact the same figure and later evolved into two.
