How did Saint Joanna die?

Joanna was the wife of Chuza, Herod's steward: "Joanna the wife of Chuza, Herod's steward" (St. Luke 8:3). When Herod beheaded John the Baptist he disposed of his head in an unclean place. Joanna removed the head of the Baptist and buried it honorably on the Mount of Olives on Herod's estate. Later, during the reign of Constantine the Great, the head of John the Baptist was discovered. St. Joanna is also remembered as being present both at the suffering and at the resurrection of the Lord. She died peacefully.
