PSEUDO PERIPTERAL (Gr. evSils, false, round,. irrep6v, a wing), a term in architecture given to a temple in which the columns surrounding the naos have had walls built between them, so that they become engaged columns, as in the great temple at Agrigentum. In Roman temples, in order to increase the size of the cella, the columns on either side and at the rear became engaged columns, the portico only having isolated columns. (See TEMPLE.)
