 On this rests the frieze, one of the major areas of sculptural decoration.The frieze is divided into "triglyphs" and "metopes", the triglyphs, as stated elsewhere in this article, are a reminder of the timber history of the architectural style.Each triglyph has three vertical grooves, similar to the columnar fluting, and below them, seemingly connected, are guttae, small strips that appear to connect the triglyphs to the architrave below.
