STYLE, in the sense of a column (from the Greek στύλος, a column), enters into a great number of useful compound terms referring to matters connected with columniation, and which may here be grouped together, so that any word ending in ‘style’ may be found here, though passed over in its alphabetical order. The number of columns in the front of a pedimented portico is briefly expressed at once by any of the following terms: Distyle in antis, two columns and two antæ. Tetrastyle ” four columns. Hexastyle ” six ” Octastyle ” eight ” Decastyle ” ten ” almost the greatest number that can be placed beneath a pediment. As regards Intercolumniation, we have—Pycnostyle—Eustyle—Aræostyle, 79. The terms descriptive of the plans and columniation of ancient temples are—Prostyle—Amphiprostyle—Peristyle, 69. Also, Monoprostyle, a prostyle with _one_ intercolumn on its flanks. Diprostyle ” ” _two_ ” ” Triprostyle ” ” _three_ ” ” To which may be added— Heterostyle, composed of different Orders, as where one Order is employed for the centre of a composition, and another for the wings. Macrostyle denotes a large Order, that is, one forming the height of the building. Microstyle, on the contrary, denotes a lesser Order, belonging only to some low division of the building, as for instance, a porch. Thus porticoes are _macrostylar_, porches _microstylar_. In Italian composition, microstylar doors and windows, _i. e._ doors and windows decorated with small columns, are of frequent occurrence. STYLOBATE.—That part of a structure on which an Order is raised, and on which the columns immediately stand. The term is, however, restricted to what partakes of the character of a pedestal, and not to a mere plinth or socle on the one hand, or to a lower fenestrated floor on the other. VOLUTE.—The characteristic ornaments and indicial marks of the Ionic capital formed by circumvolving spiral mouldings are termed volutes. The small circle in which the spiral or springs terminate is called the _eye_ of the volute. [Illustration] Printed by Hughes & Robinson, King’s Head Court, Gough Square.
