The Mary Shrine Windows
The windows in these three panels represent Mary the Mother of Jesus, Mary under her title of the Immaculate Conception and Mary as Queen of Heaven.
In the left panel the Chi-Rho stemming from a lily indicates that Christ was born of the Virgin Mary; the two over-lapping fish represent the two natures of Christ (human and divine) hypostatically united within the womb of the Virgin Mary.
The large lily filling the center panel proclaims the purity of Mary conceived immaculate in the womb of her mother, Anne.
The right panel, which contains three lilies surmounted by crowns, pays homage to the Queenship of Mary.
