Well, inasmuch as Roostem was chief Vizier, and as such had the whole of the Turkish administration in his hands, he had no difficulty, seeing that he was the Sultan’s adviser in everything, in influencing his master’s mind. The Turks, accordingly, are convinced that it was by the calumnies of Roostem and the spells of Roxolana, who was in ill repute as a practiser of witchcraft, that the Sultan was so estranged from his son as to entertain the design of getting rid of him. A few believe that Mustapha, being aware of the plans of Roostem and the practices of his stepmother, determined to anticipate them, and thus engaged in designs against his father’s throne and person. The sons of Turkish Sultans are in the most wretched position in the world, for, as soon as one of them succeeds his father, the rest are doomed to certain death. The Turk can endure no rival to the throne, and, indeed, the conduct of the Janissaries renders it impossible for the new Sultan to spare his brothers; for if one of them survives, the Janissaries are for ever asking largesses. If these are refused, forthwith the cry is heard, ‘Long live the brother!’ ‘God preserve the brother!’—a tolerably broad hint that they intend to place him on the throne. So that the Turkish Sultans are compelled to celebrate their succession by imbruing their hands in the blood of their nearest relatives. Now whether the fault lay with Mustapha, who feared this fate for himself, or with Roxolana, who endeavoured to save her children at the expense of Mustapha, this much at any rate is certain—the suspicions of the Sultan were excited, and the fate of his son was sealed. Being at war with Shah Tahmasp, King of the Persians, he had sent Roostem against him as commander-in-chief of his armies. Just as he was about to enter the Persian territory, Roostem suddenly halted, and hurried off despatches to Solyman, informing him that affairs were in a very critical state; that treason was rife everywhere; that the soldiers had been tampered with, and cared for no one but Mustapha; that he (the Sultan) could control the soldiers, but that the evil was past his (Roostem’s) curing; that his presence and authority were wanted; and he must come at once, if he wished to preserve his throne. Solyman was seriously alarmed by these despatches. He immediately hurried to the army, and sent a letter to summon Mustapha to his presence, inviting him to clear himself of those crimes of which he was suspected, and indeed openly accused, at the same time assuring him that, if he proved innocent, no danger awaited him. Mustapha had now to make his choice. If he obeyed the summons of his angry and offended father, the risk was great; but if he excused himself from coming, it would be tantamount to an admission of treason. He determined to take the course which demanded most courage and involved most danger.
