BAY

(More anciently Severy .) One whole compartment of a building. As the whole structure consists of a repetition of bays, the description of one bay comprises most of the terms used in architectural nomenclature. The accompanying block figures are purposely composed of discordant parts, to comprise the greater number of terms. IMG:2516882409276230900_i098.jpg: EXTERIOR. A. Aisle. I. Basement. II. Parapet. a.
