The Lion and the Unicorn. The lion, pretending that he was ill, came limping up to the unicorn, his chief adversary, and after greeting him, he said, "Whatever may have transpired between us so far, let that be now set aside, because I cannot manage to do you any further harm, as you can see, being worn out by old age and various illnesses. But I deeply desire to speak one last time with my wife, who is away in the desert, before my death, and I'm asking you to loan me your horn to use to as something to lean on while I travel because it is quite long and strong. I will give it back to you as soon as I reach my wife, I pledge you my word." The unicorn, trusting in the lion's words and feeling sympathy for his feigned sorrow, loaned the lion his horn and was thus left defenseless. The lion walked a little ways, and then he leaped on the unicorn and seriously wounded him with his own horn, thus defeating him.
