The delay thus gained permitted a reference of the affair to the king. It is said that Guillaume du Bellay is entitled to the honor of having informed Francis of the oppression of his poor subjects of Provence, and invoked the royal interposition.[472] However this may be, it is certain that Francis instructed Du Bellay to set on foot a thorough investigation into the history and character of the inhabitants of Mérindol, and report the results to himself. The selection could not have been more felicitous. Du Bellay was Viceroy of Piedmont, a province thrown into the hands of Francis by the fortunes of war. A man of calm and impartial spirit, his liberal principles had been fostered by intimate association with the Protestants of Germany. Only a few months earlier, in 1539, he had, in his capacity of governor, made energetic remonstrances to the Constable de Montmorency touching the wrongs sustained by the Waldenses of the valleys of Piedmont at the hands of a Count de Montmian, the constable's kinsman. He had even resorted to threats, and declared "that it appeared to him wicked and villanous, if, as was reported, the count had invaded these valleys and plundered a peaceful and unoffending race of men." Montmian had retorted by accusing Du Bellay of falsehood, and maintaining that the Waldenses had suffered no more than they deserved, on account of their rebellion against God and the king. The unexpected death of Montmian prevented the two noblemen from meeting in single combat, but a bitter enmity between the constable and Du Bellay had been the result.[473] [Sidenote: Du Bellay's favorable report.]
