What does Opus Sadicum mean?

Question

I found that Marquis de Sade is often referred as Opus Sadicum, what does that mean?

Answer 1

In later times, to avoid censorship, his works were given the generic title "Opus Sadicum" : 'Work/Book by/from (de) Sade'.

For example "Opus Sadicum : a philosophical romance." is the title of the first English translation of "Justine", printed in the Netherlands.
