St. Mary Magdalene holding a jar of ointment and a palm, with two angels

St. Mary Magdalene is often depicted in Christian art holding a jar of ointment, which is meant to symbolize the ointment she used to anoint the feet of Jesus during the Last Supper, as described in the New Testament. This act of devotion is seen as a powerful expression of Mary Magdalene's love and devotion to Jesus, she pours the ointment from the jar onto Jesus' feet.
