Marvel not, ye witty and eloquent readers, that I, thin of wit and void of cunning, have translated this book from Latin into our vulgar language, as a thing profitable to me, and peradventure to many other, which understand not Latin, nor have not the knowledge of the properties of things, which things be approved by the books of great and cunning clerks, and by the experience of most witty and noble Philosophers. All these properties of things be full necessary and of great value to them that will be desirous to understand the obscurities, or darkness of holy scriptures: which be given unto us under figures, under parables and semblance, or likelihoods of things natural and artificial. Saint Denys, that great Philosopher and solemn clerk, in his book named the heavenly hierarchies of angels, testifieth and witnesseth the same, saying in this manner:--What so ever any man will conject, feign, imagine, suppose, or say: it is a thing impossible that the light of the heavenly divine clearness, covered and closed in the deity, or in the godhead, should shine upon us, if it were not by the diversities of holy covertures. Also it is not possible, that our wit or intendment might ascend unto the contemplation of the heavenly hierarchies immaterial, if our wit be not led by some material thing, as a man is led by the hand: so by these forms visible, our wit may be led to the consideration of the greatness or magnitude of the most excellent beauteous clarity, divine and invisible. Reciteth this also the blessed apostle Paul in his epistles, saying that by these things visible, which be made and be visible, man may see and know by his inward sight intellectual, the divine celestial and godly things, which be invisible to this our natural sight. Devout doctors of Theology or divinity, for this consideration prudently and wisely read and use natural philosophy and moral, and poets in their fictions and feigned informations, unto this fine and end, so that by the likelihood or similitude of things visible our wit or our understanding spiritually, by clear and crafty utterance of words, may be so well ordered and uttered: that these things corporeal may be coupled with things spiritual, and that these things visible may be conjoined with things Invisible. Excited by these causes to the edifying of the people contained in our Christian faith of almighty Christ Jesus, whose majesty divine is incomprehensible: and of whom to speak it becometh no man, but with great excellent worship and honour, and with an inward dreadful fear. Loth to offend, I purpose to say somewhat under the correction of excellent learned doctors and wise men: what every creature reasonable ought to believe in this our blessed Christian faith.
