Castellio, Basel and Tolerance

15 December 2022

As a centre of book printing, where Erasmus worked and through its role as a mediator in religious policy, Basel became a place of refuge for religious dissidents and representatives of the Reformation in the middle of the 16th century.

They engaged in a (multilingual) discussion among themselves and with Basel citizens. When the Spaniard Michael Servet (1511-1553) was burned for heresy in Calvin’s Geneva in 1553, Basel became the centre of the protests.

The Savoyard humanist Sebastian Castellio (1515-1563) raised his voice with his courageous writings, which combined mystical piety with Enlightenment argumentation. Throughout the following centuries, his voice was heard across Europe for religious freedom, human rights, and tolerance.

The exhibition (Laboratorien der Toleranz. Sebastian Castellio und sein Erbe) presents Castellio’s life and works based on documents in the University Library of Basel.It covers historical upheavals and conflicts, networks and media, discourse, and the world of thought, making his work a turning point in the history of European tolerance thinking.
