In modern day architectural terms, Frieze is often refered to as Fascia. A Fascia board is a wide, flat horizontal piece of timber, used to cap the end of rafters. Secured to the rafters at roof level, where they meet the edge of a building, it provides the rafters and roof cavity protection from the elements. Can also be used to hold a gutter for collecting rain water or as a relief for fretwork.
In classical architecture, the fascia is the plain, wide band across the bottom of the entablature, directly above the columns.
An entablature refers to the superstructure of mouldings and bands which lie horizontally above columns, resting on their capitals.
