Abstract: The paper examines imprisonment narratives peculiar to the non-conformist culture of the seventeenth and eighteenth centuries. It studies the gap existing between, on the one hand, the seventeenth-century approach aimed at describing the prison framework, using modes proper to Baroque experimentation and a secular reversal of the evangelical Passio narrative, and, on the other hand, the distinct deployment of a chronotope of imprisonment-escape throughout the eighteenth century. This gap demonstrates changes in the status of libertine narratives.
