At no period of his life did the emperor show that he possessed ability above the average. Neither he nor any of his ministers rose above mediocrity. He nevertheless recognised the danger to his empire from the advance of the Mahometans, the powerlessness of his own unaided subjects to resist that advance, and the expediency of obtaining help from the West. In dealing with some of the questions which disturbed his subjects he possessed a certain aloofness which made him examine them as a statesman. It is probably true, as Gibbon suggests,[79] that in his appeals to Rome he was greatly influenced by his mother, Anne of Savoy. She had been brought up as a member of the Latin Church and, though compelled on her marriage to change her name and her religion, she yet remained attached to the Church and country of her childhood. Her struggles during the minority of her son had not tended to make her look with favour on the Orthodox, and her influence upon her son’s mind was probably sufficient to make him regard with as much favour the Church to which his mother had belonged as that of which he was now the temporal head. He had come to regard the differences between the two Churches as matters rather for ecclesiastics than for statesmen. He personally was ready to accept the Union of the Churches and even papal supremacy in religious matters, provided that in return he could obtain aid from the West against the enemies of the empire. But, whatever were his own sentiments towards the Church of Rome, his conduct during the long period of thirty-five years showed that he felt the need of external aid if the empire were to be saved. His reign is one long series of efforts to obtain it. He was ready to humiliate himself, to use all his powers of persuasion for Union, provided that the pontiffs would induce Western rulers to fight the Turks.
