DIAST'YLOS (διάστυλος). Having the space of three diameters between column and column, which constitutes the widest intercolumnation capable of bearing an architrave of stone or marble; for the Tuscan style, which admitted four diameters, required its architrave to be of wood. (Vitruv. iii. 2.) The annexed diagram (Diastylos/1.1) shows the relative width of the five different kinds of intercolumniation in which the diastyle is the last but one.
