"These men that have foolishly alienated themselves from a good and kind master, to seek the service of so harsh and savage a lord, that are all agog for present joys and are glued thereto, that take never a thought for the future, that always grasp after bodily enjoyments, but suffer their souls to waste with hunger, and to be worn with myriad ills, these I consider to be like a man flying before the face of a rampant unicorn, who, unable to endure the sound of the beast's cry, and its terrible bellowing, to avoid being devoured, ran away at full speed. But while he ran hastily, he fell into a great pit; and as he fell, he stretched forth his hands, and laid hold on a tree, to which he held tightly. There he established some sort of foot-hold and thought himself from that moment in peace and safety. But he looked and descried two mice, the one white, the other black, that never ceased to gnaw the root of the tree whereon he hung, and were all but on the point of severing it. Then he looked down to the bottom of the pit and espied below a dragon, breathing fire, fearful for eye to see, exceeding fierce and grim, with terrible wide jaws, all agape to swallow him. Again looking closely at the ledge whereon his feet rested, he discerned four heads of asps projecting from the wall whereon he was perched. Then he lift up his eyes and saw that from the branches of the tree there dropped a little honey. And thereat he ceased to think of the troubles whereby he was surrounded; how, outside, the unicorn was madly raging to devour him: how, below, the fierce dragon was yawning to swallow him: how the tree, which he had clutched, was all but severed; and how his feet rested on slippery, treacherous ground. Yea, he forgat, without care, all those sights of awe and terror, and his whole mind hung on the sweetness of that tiny drop of honey. "This is the likeness of those who cleave to the deceitfulness of this present life,--the interpretation whereof I will declare to thee anon. The unicorn is the type of death, ever in eager pursuit to overtake the race of Adam. The pit is the world, full of all manner of ills and deadly snares. The tree, which was being continually fretted by the two mice, to which the man clung, is the course of every man's life, that spendeth and consuming itself hour by hour, day and night, and gradually draweth nigh its severance. The fourfold asps signify the structure of man's body upon four treacherous and unstable elements which, being disordered and disturbed, bring that body to destruction. Furthermore, the fiery cruel dragon betokeneth the maw of hell that is hungry to receive those who choose present pleasures rather than future blessings. The dropping of honey denoteth the sweetness of the delights of the world, whereby it deceiveth its own friends, nor suffereth them to take timely thought for their salvation." XIII.
