Wheat’s origins are unknown but is the basis of basic food and a staple in many cultures. Because of wheat’s exalted position as a mainstay foodstuff, it is viewed as a gift from Heaven.
Wheat symbolizes immortality and resurrection. But, like many symbols found on gravestones, they can have more than one meaning. For instance, because wheat is the main ingredient of bread, the sheaf of wheat can represent the Body of Christ. Wheat can also represent a long life, usually more than three score and ten, or seventy years.
Coupled with the epitaph, “Gathered Home,” the wheat, in this case, suggests that the sheafs of wheat are gathered together like Christian souls on their way to Heaven.
