From this anti-chamber we passed on to one much larger, the roof of which was supported by large columns, and illuminated by many lustres. In the middle there was a cistern, and on each side we observed various sorts of provisions. We were much surprised at not seeing any one. Opposite to us, there was a raised sofa, to which they ascended by some steps, and beyond this there appeared a very large bed, the curtains of which were drawn. The king went up, and undrawing them, discovered the prince, his son, and the lady in bed together, but burnt and changed into a coal, as if they had been thrown on to an immense fire, and had been taken off before they were consumed. What surprised me even more than this sight itself was, that my uncle did not evince any sorrow or regret at seeing his son in this horrid state. He spit in his face, and said in an enraged manner, “See what is the punishment of this world, but that of the next will be eternal.” Not satisfied with saying this, he pulled off his slipper and gave his son a great blow on his cheek.

I cannot express the astonishment I felt at seeing the king, my uncle, treat his son in that manner after his death. “Sire,” said I to him, “however violent my grief may be at seeing so heart-rending an object, yet I cannot yield to it without first inquiring of your majesty, what crime the prince, my cousin, can have committed to deserve such treatment of his lifeless corpse.” The king thus replied: “Nephew, I must inform you that my son, unworthy such a title, loved his sister from his earliest years, and was equally beloved by her. I rather encouraged their rising friendship, because I did not foresee the danger that was to ensue. And who could have foreseen it? This affection increased with their years, and reached to such a pitch, that I dreaded the consequences. I applied the only remedy then in my power. I severely reprimanded my son for his conduct, and represented to him the horrors that would arise if he persisted in it; and the eternal shame that would tarnish our family, if he indulged himself in so criminal a passion.

“I talked to his sister in the same terms, and confined her, that she should have no further communication with her brother. But the unhappy girl had tasted of the poison, and all the obstacles that my prudence suggested, only irritated their passion.
