Bonus Eventus ("Good Outcome") was a divine personification in ancient Roman religion. The Late Republican scholar Varro lists him as one of the twelve deities who presided over agriculture,[1] paired with Lympha, the goddess who influenced the water supply. The original function of Bonus Eventus may have been agricultural,[2] but during the Imperial era, he represents a more general concept of success and was among the numerous abstractions who appeared as icons on Roman coins.
