The three wooden poles that support the tree of Patience and aid Piers Plowman in attacking evil forces who try to steal the tree’s fruits symbolize the Trinity. Will notices that the three poles are each fashioned out of wood from the same tree—underscoring the idea that God is both three and one—that is, God the Father, God the Son (Jesus), and the Holy Ghost. By relying on the three wooden poles—the Trinity—Piers Plowman is able to keep the tree of Patience (the Christian community) supported and safe.
