In due course the foundations were laid, and Josse supervised the building operations for something like sixteen years, and then things came to a standstill--a dispute, seemingly, with the dean and chapter, who refused to pay him his wages. He appealed to the city magistrates; and they, having vainly essayed to arrange matters, commissioned him to carve for them in stone an exact model of the projected building (August 1524), partly because they thought old Josse had been harshly treated and they knew he was poor, and partly because such a model would be useful to his successor, for he was now a very old man, and Death sat close to him. The issue proved how wise they were. He died shortly afterwards (May 1530), and his towers are unfinished still; but the master-mason who shall one day complete them will have no excuse if he fail to realise the old locksmith's glorious dream, for he lived long enough to make the model (1529), and along with his plans it is still preserved in the archive chamber of the Town Hall. In all probability, the greater part of it was not carved by Metsys himself, but the work was all done under his supervision; and the man who helped him, it will be interesting to note, was his son-in-law, Jan Beyaert. It was most likely about this time that Meester Jan set to work on his stalls, for we know that they were the gift of Abbot Peter Was, who ruled Saint Gertrude's from 1527 to 1546. An elaborate work of this kind must have taken a man like Beyaert many years to complete; he died in 1543, and for a considerable period before his death he had ceased to occupy himself with art. He had taken up theology instead, and that was his undoing. It happened thus: Calvinism was now making headway in all the towns of the Netherlands, Catherine embraced the new doctrine, she was a woman of will and of energy, and soon she became the leading spirit of the little band of Protestants at Louvain. Of course she had no difficulty in persuading her husband to join them, and soon the poor artist was converted into a hot Gospeller. Strange irony of fate that the man who had made graven images all his life should end his days an iconoclast. He did not turn his hand against his own work; perhaps he still, in spite of his wife, had a sneaking tenderness for sculpture, but his practice squared with his preaching in the matter of pictures, and one night, toward the close of the year 1542, or early in 1543, he broke into the Church of Saint Pierre, and then into the Church of Saint Jacques, in each of them wrecked several valuable paintings, and afterwards, with the fragments, made a bonfire in the Grand' Place. Presently he was arraigned for heresy and sacrilege, found guilty, and condemned to the stake. Hope, however, seems to have been held out to him that if he would give evidence against his accomplices the sentence would be reconsidered, and at last, under torture, he opened his mouth,
