Architrave in the context of "Entablature"

The Doric order is one of the three orders of ancient Greek and later Roman architecture; the other two canonical orders were the Ionic and the Corinthian. The Doric is most easily recognized by the simple circular capitals at the top of the columns. Originating in the western Doric region of Greece, it is the earliest and, in its essence, the simplest of the orders, though still with complex details in the entablature above.

The Greek Doric column was fluted, and had no base, dropping straight into the stylobate or platform on which the temple or other building stood. The capital was a simple circular form, with some mouldings, under a square cushion that is very wide in early versions, but later more restrained. Above a plain architrave, the complexity comes in the frieze, where the two features originally unique to the Doric, the triglyph and gutta, are skeuomorphic memories of the beams and retaining pegs of the wooden constructions that preceded stone Doric temples. In stone they are purely ornamental.

A metope (/ˈmɛtəpi/; Ancient Greek: μετόπη) is a rectangular architectural element of the Doric order, filling the space between triglyphs in a frieze, a decorative band above an architrave.In earlier wooden buildings the spaces between triglyphs were first open, and later the free spaces in between triglyphs were closed with metopes; however, metopes are not load-bearing part of a building.Earlier metopes are plain, but later metopes were painted or ornamented with reliefs. The painting on most metopes has been lost, but sufficient traces remain to allow a close idea of their original appearance.

In terms of structure, metopes were made out of clay or stone. A stone metope may be carved from a single block with a triglyph (or triglyphs), or they may be cut separately and slide into slots in the triglyph blocks as at the Temple of Aphaea. Sometimes the metopes and friezes were cut from different stone, so as to provide color contrast. Although they tend to be close to square in shape, some metopes are noticeably larger in height or in width. They may also vary in width within a single structure to allow for corner contraction, an adjustment of the column spacing and arrangement of the Doric frieze in a temple to make the design appear more harmonious.

In classical architecture, the frieze /friːz/ is the wide central section of an entablature and may be plain in the Ionic or Corinthian orders, or decorated with bas-reliefs. Paterae are also usually used to decorate friezes. Even when neither columns nor pilasters are expressed, on an astylar wall it lies upon the architrave ("main beam") and is capped by the moldings of the cornice. A frieze can be found on many Greek and Roman buildings, the Parthenon Frieze being the most famous, and perhaps the most elaborate.

In interiors, the frieze of a room is the section of wall above the picture rail and under the crown moldings or cornice. By extension, a frieze is a long stretch of painted, sculpted or even calligraphic decoration in such a position, normally above eye-level. Frieze decorations may depict scenes in a sequence of discrete panels. The material of which the frieze is made may be plasterwork, carved wood or other decorative medium.

A monolith is a geological feature consisting of a single massive stone or rock, such as some mountains. Erosion usually exposes the geological formations, which are often made of very hard and solid igneous or metamorphic rock. Some monoliths are volcanic plugs, solidified lava filling the vent of an extinct volcano.

In architecture, the term has considerable overlap with megalith, which is normally used for prehistory, and may be used in the contexts of rock-cut architecture that remains attached to solid rock, as in monolithic church, or for exceptionally large stones such as obelisks, statues, monolithic columns or large architraves, that may have been moved a considerable distance after quarrying. It may also be used of large glacial erratics moved by natural forces.

A gutta (Latin pl. guttae, "drops") is a small water-repelling, cone-shaped projection used near the top of the architrave of the Doric order in classical architecture. At the top of the architrave blocks, a row of six guttae below the narrow projection of the taenia (fillet) formed an element called a regula. A regula was aligned under each triglyph of the Doric frieze. In addition, the underside of the projecting geison above the frieze had rectangular protrusions termed mutules that each had three rows of six guttae. These mutules were aligned above each triglyph and each metope.

It is thought that the guttae were a skeuomorphic representation of the pegs used in the construction of the wooden structures that preceded the familiar Greek architecture in stone. However, they have some functionality, as water drips over the edges, away from the edge of the building.

In architecture, an abacus (from the Ancient Greek ἄβαξ (ábax), 'slab'; or French abaque, tailloir; pl.: abacuses or abaci) is a flat slab forming the uppermost member or division of the capital of a column, above the bell. Its chief function is to provide a large supporting surface, tending to be wider than the capital, as an abutment to receive the weight of the arch or the architrave above. The diminutive of abacus, abaculus, is used to describe small mosaic tiles, also called abaciscus or tessera, used to create ornamental floors with detailed patterns of chequers or squares in a tessellated pavement.
