Seven wise mastersthe most common title given to a famous medieval collection of stories grouped round a central story of the birth, education, and trials of a young prince. Accused like Joseph, he is sentenced to death, but each one of the seven viziers gains a day, out of the fated seven during which the prince may not open his mouth, by two tales against women. At the end of the seventh day the prince is free to speak, and quickly clears his character
