A Brief Notice of the Destruction of the Tyrants
With respect to the other princes, who made war against the churches of God, I have not thought it fit in the present work to give any account of their downfall, nor to stain the memory of the good by mentioning them in connection with those of an opposite character. The knowledge of the facts themselves will of itself suffice for the wholesome admonition of those who have witnessed or heard of the evils which severally befell them.
