Fr. Gabriel Roschini, one of the most eminent Mariologists of the twentieth century, was so impressed by The Poem that he wrote a work entitled The Virgin Mary in the Writings of Maria Valtorta. He had this to say on The Poem:
I must candidly admit that the Mariology found in Maria Valtorta’s writings, whether published or not, has been for me a real discovery. No other Marian writing, not even the sum total of all the writings I have read and studied were able to give me as clear, as lively, as complete, as luminous, or as fascinating an image, both simple and sublime, of Mary, God’s masterpiece.
