It is wonderful to see how well he knew how to secure the good-will of dignitaries, secular or ecclesiastical, by low flattery expressed in classic language. He exhibited very markedly certain qualities not infrequently observed in eminent Humanists, viz. want of character, fickleness in words and behaviour and extraordinary sensitiveness to criticism. His vanity was matched by the petty vindictiveness of the satires with which he lashes his opponents, and all who dared to disagree with him. Material assistance from the great ones of the earth was never lacking to him, the demi-god of the intellectual sphere; when declining an invitation to go to Germany he could say: “The Emperor implores me to come to Spain, King Ferdinand wants me at Vienna, Margaret in Brabant and Henry in England; Sigismund asks me to go to Poland and Francis to France, and all offer me rich emoluments.”[689] It is not surprising, that when Luther came forward many elements of his new teaching were at once welcomed with sympathy by Erasmus and his school. “It cannot be denied, that Luther commenced to play an excellent part and to vindicate the cause of Christ--which had been almost wiped off the face of the earth--amidst great and general applause.”[690] Thus wrote Erasmus to Duke George of Saxony as late as 1522. Many of Erasmus’s sayings in his books and confidential letters in favour of Luther’s reform were cherished as oracles. His testimonies in favour of Luther’s writings and his private life were spread far and wide, though he really knew little of Luther’s works (those written in German he could not even read), and owed all his information concerning his life to Humanist friends who were prejudiced in Luther’s favour. It was true that he was not personally acquainted with Luther, he wrote on April 14, 1519, from Antwerp to Frederick the Elector of Saxony, and, of his writings, he had, so far, read only certain extracts;[691] “but all who were conversant with his life approved of it, since he was above every suspicion of ambition. The purity of his character is such that he even wins over the heathen. No one has shown his error or refuted him, and yet they call him a heretic.” Hence he urges the Prince not to abandon an innocent man to malicious persons.[692] It was probably this letter which confirmed the Elector in his determination not to withdraw from Luther his protection. “Luther’s life is approved by everyone here,” Erasmus writes on April 22 of the same year from Louvain to Melanchthon; “opinions differ with regard to his learning.... Luther has rightly found fault with some things, would that he had done so with a success equal to his courage.”[693] His letters to England are in the same strain: “All are agreed in praise of this man’s life. It is in itself no small matter that his conduct is so blameless that even his enemies can find nothing with which to reproach him.”[694]
