[Sidenote: 1564.] Had he not died of the plague in prison he would probably have suffered the same fate as Servetus. [Sidenote: Complete theocracy, 1555] Strengthened by his victory over heresy, Calvin now had the chance to annihilate his opponents. On May 15, 1555, he accused a number of them of treason, and provided proof by ample use of the rack.
