Or, "how literature teaches us beautiful things."
Yesterday, I told Ramona, "We get to go to Mass, to celebrate Mary's Immaculate Conception!"
She replied, "Oh, yes! Mary -- the ship! The rose!"
And I realized that she was recalling the images of Mary from Barbara Helen Berger's lovely book, The Donkey's Dream, which introduces children to traditional imagery for the Blessed Virgin.
For more about the imagery (a city, a ship, a fountain, a rose, a lady full of heaven) in this exquisitely illustrated book, see this link at the author's website.
For more indepth information, see this excellent article from Ignatius Insight.
