The Mask reveals the reasons for progress and success through what its author narrated about thousands of great men, what they did until they achieved the highest level, and their suffering until they achieved glory. It was written by the English writer Samuel Samuels, and it was translated into most European languages, and its people accepted reading it, and its benefits became famous among them, to the point that their kings presented its author with precious gifts in recognition of his merit, and testified to him that he was the best book created to advance the status of their subjects.
