The physician Douban entered the hall and bowed low to the ground. The king, seeing him, called him, made him sit by his side, and showed him every mark of honour. That evening he gave him a long and rich robe of state, and presented him with two thousand sequins. The following day he continued to load him with favours.

Now the king had a grand-vizir who was avaricious, and envious, and a very bad man. He grew extremely jealous of the physician, and determined to bring about his ruin.
