Many great works about the Blessed Virgin Mary exist in Latin, and one I recently discovered is by Denis the Carthusian. He lived in the 15th century, dedicated much of his life to prayer, study, and writing, and wrote a number of profound theological works.
One of his works on Our Lady is a treatise called De praeconio et dignitate Beatae Virginis Mariae. I think one could say “Of the proclamation and the dignity of the Blessed Virgin Mary.” It consists of 4 books, and they are contained in volume 35 of his Opera Omnia, which is, like many old books these days, available free online. The work begins on page 477.
A few headings: Of the enmity which has arisen between the Woman and the serpent.
What then is the enmity this Lady has toward the serpent?
That the same Son eternally begotten of the Father was born of Blessed Mary in time.
That the glory, dignity, and grace of Mary is indescribable, and in some sense infinite.
Of the incomparable fruitfulness of Mary
A comparison of the fecundity of the Holy Virgin to the fecundity of the Eternal Father…
Would that someone could translate these works….
