Joseph kneels outside the temple, among, according to the text, a group of unmarried men. The artist has depicted them dressed like contemporary Portuguese merchants wearing button-down belted shirts. The men had been ordered by God to bring their staffs to the temple; the one whose staff blossoms would become the husband of Mary. Joseph quivers with astonishment as his staff blooms; his hat falls to the ground as though it suddenly came off his head in surprise. Father Jerome’s source for this episode was the apocryphal Gospel of Pseudo-Matthew.
