The Ambarvalia was a ritual to purify the fields of evil influences. It was a movable feast, but May 29 possibly became regarded as a customary date. A suovetaurilia, a procession of a pig, sheep, and ox, was led around the area involved three times and then sacrificed to the appropriate deities, possibly Ceres, Mars, and Bacchus.


One day in May was to
Lustrate the farmlands with
Victims in tow;
Farmers and families
Circled the boundaries three
Times in a row.
