A type of Roman edifice that displayes a series of engaged columns all around the entire cella of a temple. In other words, this is the use of fake columns carved into walls on the inside of a Roman temple that serve no other use than to sit there and look neat. Romans did this to continue the the exterior motif that they always used. It was something of an unwritten building code to the Greeks that all structures should have either doric, ionic, or corenthian columns. So, the Romans, who assimilate many of the cultures they over thow, in many cases extended this idea to their own construction, although not for the same reasons. Instead of having mean or symbolism to the construction, they just looked nice.
