An antefix (from Latin antefigere, to fasten before) is a vertical block which terminates the covering tiles of a tiled roof. In grand buildings the face of each stone ante-fix was richly carved, often with the anthemion ornament. In less grand buildings moulded ceramic ante-fixes, usually terracotta, might be decorated with figures or other ornament, especially in the Roman period. By this time they were found on many large buildings, including private houses.
From Latin antefixa, pl. of antefixum, something fastened in front, from antefixus, fastened in front: ante-, ante- and fixus, fastened, past participle of figere, to fasten.
