The central columns were then tied to the perimeter walls by fragments of rectilinear entablature, which absorb the irregularities of the atrium plan: in this way he realised a sort of system of serliane, a stratagem conceptually similar to that of the Basilica Palladiana loggias. Palladio even adopted the unusual type of Ionic capital (derived from the Temple of Saturn in the Forum Romanum) because it permitted him to mask the slight but significant rotations necessary to align the columns and engaged columns.
