The architrave, frieze, and cornice are the three components of a Doric entablature. The architrave is made up of stone lintels that span the gap between the columns. The frieze, one of the major areas of sculptural decoration, sits atop this. The frieze is split into two sections: triglyps and metopes. Triglyps are three-inch (7.5 cm) blocks with a decorative sculpture on each side. Metopes are six-inch (15 cm) blocks with a decorative carving at the center. Doric order had no acanthus or other naturalistic plantings as adornments to its temples. Instead, the artist used geometry to create an effect of movement and vitality out of simple shapes. The frieze was divided into blocks with varying sizes and shapes of holes drilled through them. These holes were used for tying off the cords that held the roof tiles in place. The main purpose of the frieze was to display sculptures of animals, warriors, gods, and other themes relevant to Greek religion at the time. However, since the triglyps were available only after finishing the metope, many artists chose instead to work on these smaller pieces first. This allowed them to test out new ideas before committing to larger projects. Some artists even used the holes in the triglyphs to store pigments while they worked. Overall, the Doric temple style was used primarily for religious structures.
