Tetrastyle, tet′ra-stīl, n. a temple or other building having four front columns in its portico: a group of four pillars.—adj. having four pillars.

The temple, which is entirely of Pentelic marble, is amphiprostyle tetrastyle, with fluted Ionic columns, on a stylobate of three steps; its length is 27 ft., its breadth 18� ft., and its total height, from the apex of the pediment to the bottom of the steps, 23 ft.

The main approach on the north side is through a tunnel, above which, on a projecting rock, stands the cemetery chapel, built in the form of a small Doric temple with tetrastyle porticos.

The Courts of Houses were of five sorts, four whereof were made with jettings out, or Pent-houses of four sorts. the Tuscan, 137. the Corinthian, the Tetrastyle, the Vaulted, 138. the fifth sort uncoverted, 138.

The third Sort was called Tetrastyle, because the Beams were supported with four Pillars which were in the place of the standing Beams that were made use of in the Tuscan Court.
