Fabula palliata
.
Fabula palliata is a genre of Roman drama that consists largely of Romanized versions of Greek plays. Palliata comes from pallium, the Latin word for a Greek-style cloak. It is possible that the term fabula palliata indicates that the actors who performed wore such cloaks. Another possibility is that the fabula itself is metaphorically "cloaked" in a Greek style. As in all Roman drama, the actors wore masks that easily identified which of the stock characters they represented.
