A cavetto is a concave moulding with a regular curved profile that is part of a circle, widely used in architecture as well as furniture, picture frames, metalwork and other decorative arts. In describing vessels and similar shapes in pottery, metalwork and related fields, "cavetto" may be used of a variety of concave curves running round objects. The word comes from Italian, as a diminutive of cave, from the Latin for "hollow" (it is the same root as cave). [1] A vernacular alternative is "cove", most often used where interior walls curve at the top to make a transition to the roof, or for "upside down" cavettos at the bases of elements. [2]
The cavetto moulding is the opposite of the convex, bulging, ovolo, which is equally common in the tradition of Western classical architecture. Both bring the surface forward, and are often combined with other elements of moulding. Usually they include a curve through about a quarter-circle (90°). [3] A concave moulding of about a full semi-circle is known as a "scotia". [4]
Only a minor element of decoration in classical architecture, the prominent cavetto cornice is a common feature of the ancient architecture of Egypt and the Ancient Near East.
Ancient Egyptian architecture made special use of large cavetto mouldings as a cornice, with only a short fillet (plain vertical face) above, and a torus moulding (convex semi-circle) below. This cavetto cornice is sometimes also known as an "Egyptian cornice", "hollow and roll" or "gorge cornice", and has been suggested to be a reminiscence in stone architecture of the primitive use of bound bunches of reeds as supports for buildings, the weight of the roof bending their tops out. [5]
Many types of Egyptian capitals for columns are essentially cavettos running round the shaft, often with added decoration. These include the types known as "bell capitals" or "papyrus capitals". These features are often reproduced in Egyptian Revival architecture, as in the Egyptian Building (1845) in Richmond, Virginia. [6]
The cavetto cornice, often forming less than a quarter-circle, influenced Egypt's neighbours and as well as appearing in early Greek architecture, it is seen in Syria and ancient Iran, for example at the Tachara palace of Darius I at Persepolis, completed in 486 BC. Inspired by this precedent, it was then revived by Ardashir I (r. 224–41 AD), the founder of the Sasanian dynasty. [7]
The cavetto took the place of the Greek cymatium in many Etruscan temples, [8] often painted with vertical "tongue" patterns, and combined with the distinctive "Etruscan round moulding", often painted with scales. [9]
This emphasis on the cavetto was very different from its role in mature Ancient Greek architecture, where cavetto elements were relatively small and subordinated to essentially vertical elements, setting the style for the subsequent Western classical tradition. [10] Often an essentially cavetto section is heavily decorated, in Gothic architecture often smothering the shape beneath.
In general the Greeks made much more use of the cyma moulding, where a cavetto and ovolo were placed one above the other to produce a "S" shape; the cymatium using this was a standard part of the cornice in the classical Ionic order, and often used elsewhere. There are two forms, depending on which curve is uppermost: in the cyma recta the cavetto is on top, in the cyma reversa the ovolo. A cavetto alone was sometimes employed in the place of the cymatium of a cornice, as in the Doric order of the Theatre of Marcellus in Rome, [8] one of the standard models for revived classical architecture from the Renaissance onwards. [11] But small cavetto mouldings were normal at various places, including integrated ones, not distinguished as a distinct zone by lines or borders, at the bottom of the shaft of columns, beginning the transition to the wider base. These are called an apophyge, or "concave sweep". [12]
Claude Perrault, one of the architects of Louis XIV's rebuilding of the Louvre Palace, especially the Louvre Colonnade, explained in his architectural textbook Ordonnance for the five kinds of columns after the method of the Ancients (1683) why he had replaced a cavetto with a cyma in his illustration of the Doric capital: "a cavetto is not as strong and is more readily broken than the other molding". [13]
In plates and other flattish shapes, cavetto is used for the curving area linking the base and the rim. This is the case whether the rim is a broad flat surface (typical 20th-century Western plate), or merely the edge of the cavetto (typical modern cereal bowl). Normally the term refers to the top surface of the vessel; if the underside is meant (where the curve is now convex), that may be described as "under the cavetto", "under-cavetto" and so forth. [14]
The cavetto is very often left undecorated, but may have decoration of a different sort from the middle or a flat rim, and the term is typically used when it is necessary to describe this. In complicated pottery shapes, where the normal vocabulary of mouldings is appropriate, cavetto may be used in that sense for any concave curving section. [15]
In the terminology of archaeology, especially relating to pottery (and generally not used of pottery after antiquity, or outside archaeology), a cavetto zone or cavetto is a "sharp concavity encircling the body of a vessel", and also a "deep but narrow neck", both used in relation to mainly upright vessels for storing or cooking food. [16]
Ancient Greek architecture came from the Greek-speaking people whose culture flourished on the Greek mainland, the Peloponnese, the Aegean Islands, and in colonies in Anatolia and Italy for a period from about 900 BC until the 1st century AD, with the earliest remaining architectural works dating from around 600 BC.
The Doric order was 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 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 Ionic order is one of the three canonic orders of classical architecture, the other two being the Doric and the Corinthian. There are two lesser orders: the Tuscan, and the rich variant of Corinthian called the composite order. Of the three classical canonic orders, the Corinthian order has the narrowest columns, followed by the Ionic order, with the Doric order having the widest columns.
An ogee ( ) is the name given to objects, elements, and curves—often seen in architecture and building trades—that have been variously described as serpentine-, extended S-, or sigmoid-shaped. Ogees consist of a "double curve", the combination of two semicircular curves or arcs that, as a result of a point of inflection from concave to convex or vice versa, have ends of the overall curve that point in opposite directions.
In architecture the capital or chapiter forms the topmost member of a column. It mediates between the column and the load thrusting down upon it, broadening the area of the column's supporting surface. The capital, projecting on each side as it rises to support the abacus, joins the usually square abacus and the usually circular shaft of the column. The capital may be convex, as in the Doric order; concave, as in the inverted bell of the Corinthian order; or scrolling out, as in the Ionic order. These form the three principal types on which all capitals in the classical tradition are based. The Composite order established in the 16th century on a hint from the Arch of Titus, adds Ionic volutes to Corinthian acanthus leaves.
In architecture, an abacus 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.
In architecture, a cornice is generally any horizontal decorative moulding that crowns a building or furniture element—for example, the cornice over a door or window, around the top edge of a pedestal, or along the top of an interior wall. A simple cornice may be formed just with a crown, as in crown moulding atop an interior wall or above kitchen cabinets or a bookcase.
An entablature is the superstructure of moldings and bands which lies horizontally above columns, resting on their capitals. Entablatures are major elements of classical architecture, and are commonly divided into the architrave, the frieze, and the cornice. The Greek and Roman temples are believed to be based on wooden structures, the design transition from wooden to stone structures being called petrification.
Moulding, or molding, also coving, is a strip of material with various profiles used to cover transitions between surfaces or for decoration. It is traditionally made from solid milled wood or plaster, but may be of plastic or reformed wood. In classical architecture and sculpture, the moulding is often carved in marble or other stones. In historic architecture, and some expensive modern buildings, it may be formed in place with plaster.
The ovolo or echinus is a convex decorative molding profile used in architectural ornamentation. Its profile is a quarter to a half of a more or less flattened circle.

Situla, from the Latin word for bucket or pail, is the term in archaeology and art history for a variety of elaborate bucket-shaped vessels from the Iron Age to the Middle Ages, usually with a handle at the top. All types may be highly decorated, most characteristically with reliefs in bands or friezes running round the vessel.
Cymatium, the uppermost molding at the top of the cornice in the classical order, is made of the s-shaped cyma molding, combining a concave cavetto with a convex ovolo. It is characteristic of Ionic columns and can appear as part of the entablature, the epistyle or architrave, which is the lintel or beam that rests on the capitals of columns, and the capital itself. Often the cymatium is decorated with a palmette or egg-and-dart ornament on the surface of the molding.
The heights of the parts of the capital are to be so regulated that three of the nine parts and a half, into which it was divided, lie below the level of the astragal on the top of the shaft. The remaining parts are for the cymatium, abacus, and channel. The projection of the cymatium beyond the abacus is not to be greater than the size of the diameter of the eye [of the volute].
A fleuron is a flower-shaped ornament, and in architecture may have a number of meanings:
Pottery was produced in enormous quantities in ancient Rome, mostly for utilitarian purposes. It is found all over the former Roman Empire and beyond. Monte Testaccio is a huge waste mound in Rome made almost entirely of broken amphorae used for transporting and storing liquids and other products – in this case probably mostly Spanish olive oil, which was landed nearby, and was the main fuel for lighting, as well as its use in the kitchen and washing in the baths.
Ancient Greek art stands out among that of other ancient cultures for its development of naturalistic but idealized depictions of the human body, in which largely nude male figures were generally the focus of innovation. The rate of stylistic development between about 750 and 300 BC was remarkable by ancient standards, and in surviving works is best seen in sculpture. There were important innovations in painting, which have to be essentially reconstructed due to the lack of original survivals of quality, other than the distinct field of painted pottery.
Etruscan architecture was created between about 900 BC and 27 BC, when the expanding civilization of ancient Rome finally absorbed Etruscan civilization. The Etruscans were considerable builders in stone, wood and other materials of temples, houses, tombs and city walls, as well as bridges and roads. The only structures remaining in quantity in anything like their original condition are tombs and walls, but through archaeology and other sources we have a good deal of information on what once existed.
An anta capital is the crowning portion of an anta, the front edge of a supporting wall in Greek temple architecture. The anta is generally crowned by a stone block designed to spread the load from superstructure (entablature) it supports, called an "anta capital" when it is structural, or sometimes "pilaster capital" if it is only decorative as often during the Roman period.
