 The reliefs were used as friezes at the top of a wall below the roof, and in other exterior locations, such as ridge tiles and antefixes, but also as decoration of interiors, typically with a number of sections forming a horizontal frieze.They were produced in unknown quantities of copies from moulds and served as decoration for temples as well as public and private buildings, as cheaper imitations of carved stone friezes.They originated in the terracotta tiled roofs of the Etruscan temples.
