The merchant returns bringing a young slave who is really the son of the princess of Rum, now married to the king, from a Tuti-nama (Tales of a Parrot): Fiftieth Night

The princess of Rum watches anxiously from an upper window as her son is introduced to the enthroned king. In order to hide his identity, she has told her husband that the young man has expert knowledge of precious gemstones. The king, impressed with the slave's skill, welcomes him into his court.
