Need your help: Theologians who wrote from prison?

I am working on a writing project and I want your help trying to find theologians (including Biblical scholars) who wrote while they were in prison/jail. Obviously we have Bonhoeffer and I thought of Kasemann as well. Who else? Doesn’t need to be Germans! It could be anywhere, anytime, but if you can point me to both person and the text, that would help!

NB: I am already aware that Paul wrote from prison!
