Some four centuries ago, thousands of Christians died because they dared to refuse to join the state church in medieval Europe. Their reading of the Holy Bible and their consciences led them to believe that church membership should be a voluntary, adult decision. These believers died public, tortured deaths as martyrs. Many modern-day Christians claim these persons of courage as their spiritual ancestors. In the late 1600s, many of those scenes were etched on copper plates, some of which, still exist. Mirror of the Martyrs reproduces 30 of those etchings and tells the courageous stories of these people of faith.
