man of learning and experience, sagacious and skilful in business, and said to him, 'I mean to go forth alone to-night and enquire into the matter of the lake and these fish: wherefore do thou sit down at the door of my pavilion and tell the amirs and viziers and chamberlains and officers and all who ask after me that the Sultan is ailing and hath ordered thee to admit no one, and do thou acquaint none with my purpose.' The Vizier dared not oppose his design; so the King disguised himself and girt on his sword and going forth privily, took a path that led over one of the hills and fared on all that night and the next day, till the heat overcame him and he paused to rest.

So he returned to the vestibule and sitting down between the doors, fell to musing upon what he had seen, when lo, he heard a moaning that came from a sorrowful heart, and a voice chanted the following verses:
