Intro

Luther's vivid, wild words – powered by new printing technology – set in motion a chain reaction that split the Catholic Church, powered the Reformation and changed the world forever. Naomi Alderman meets this determined thinker.

Famously, Luther walked up to a church in a backwater town and nailed his Ninety-five Theses to the door. The son of a metal smelter, he knew how rough and dangerous life could be; and he was prepared to question, argue and openly insult powerful authorities in defence of his explosive theology.
