Out of the ten books of "Controversiae", in which extracts from declamatory treatments of seventy-four judicial themes were presented, only books 1, 2, 7, 9, 10 survive more or less in their entirety, with the names of individual rhetoricians and Seneca's critical comments included. Such information as we have about the remaining books is supplied by an epitome made in the 4th or 5th century for school use, which was to leave its mark on later European literature by supplying some of the stories included in the anecdote-collection called "Gesta Romanorum"
