It was determined at Frankfort that another assembly should be held in the course of the summer. Melanchthon, soon after his arrival in that town, had seen in a dream a large picture in which was represented the figure of Christ on the cross, and around him souls clothed in white. The electors of the empire, bearing the ensigns of their dignity, were approaching it in regular order. Next after them came an ass, covered with a linen cope and dragging after him with a rope the emperor and the pope, as if he were going to conduct them to that assembly of the blessed.[785] ‘I think,’ said Myconius, who was then at Frankfort, ‘that it is the Germanic ass which the emperor and the pope have hitherto ridden so hard and miserably treated.’ The good Melanchthon was very much taken up with the thought of leading to Christ all the German princes, and even the emperor and the pope; and it appears that in his great humility he had represented himself in his dream under the figure of an ass. Luther in his reply thinks decidedly that it was a two-footed ass.[786] Be that as it may, the assembly at Frankfort does not appear to have led anybody to the crucified, and especially neither pope nor emperor. It would have taken more than one rope to draw them thither. Calvin did not wait for the close of the colloquy to return to Strasburg. CHAPTER XVI. CALVIN’S RELATIONS WITH SADOLETO. (1539.)
