Now, since the beasts themselves were abused and possessed by the damned Spirits, as in the beginning the Paradise Serpent, and in the holy age the herd of swine, that with a loud noise was precipitated into the sea, and since, also, the constellations are pictured on the Heavens in the forms of animals, as hath been thought even by the Prophets, as the Pleiades, or Seven Stars, and Arcturus, Orion, and Lucifer; so may it please you to overlook the elaborateness and the didacticism of this drama, if the unfortunate Spirits upon our stage, by means of the same, help and defend themselves: for to the infernal monsters nothing is more natural than cunning traits and the abuse of all creatures and elements, to the prejudice of the name and honor of the Most High, so far as He shall this permit.
St. John, in his Revelation, typifies the heavenly mysteries and the war in Heaven by the Dragon, whose tail drew after him a third part of the stars, supposed by the theologians to refer to the fallen Angels; wherefore in Poetry the flowered manner of expression should not be examined too narrowly, nor regulated by the subtlety of the schools.
We should also make distinction between the two kinds of characters who contend on this stage; namely, the bad and the good Angels, each kind playing its own rôle, even as Cicero and our inborn sense of verisimilitude teach us to picture each character according to his rank and nature.
At the same time we by no means deny that holy subject matter restrains and binds the dramatist more closely than worldly histories or pagan fables, notwithstanding that ancient and famous motto of the poets, expressed by Horatius Flaccus in his "Art of Poetry" in these lines:
"The painter and the bard did both this power receive, To aid their art with all that they of use believe."
Though here it is especially noteworthy to state how we, in order to inflame the hate of the proud and envious Spirits the more strongly, did cause the mystery of the future incarnation of the Word to be partially revealed to the Angels by the Archangel Gabriel, Ambassador from God, and Herald of His Mysteries; herein to improve the matter, following not the opinion of the majority of the theologians, but only of a few, because this furnished our tragic picture richer material and more lustre. However, neither in this point nor in other circumstances of cause, time, place, and manner (which we employed to render this tragedy more powerful, more glorious, more natural, and more instructive) has it been our purpose to obscure the orthodox truth, or to establish anything after our own finding or notion.
