Is There a Roman Prisoner of War?

Cleopatra may have committed suicide to avoid becoming a roman prisoner of war. The romans were harsh on those high level prisoners who were taken to rome in chains, and then did normally, almost always, meet an infamous end. We still don't have a lot of evidence that there was any substantial monument of isis at tapesiris. If it's possible, tapezeris is s a candidate location. It also raises the possibility that the very body and the burial and the coffin and all the gravegoods could be discovered without us knowing.
