Columns in Roman architecture

The Corinthian order is the last developed of the three principal classical orders of ancient Greek and Roman architecture. The other two are the Doric order which was the earliest, followed by the Ionic order. When classical architecture was revived during the Renaissance, two more orders were added to the canon, the Tuscan order and the Composite order. The Corinthian, with its offshoot the Composite, is stated to be the most ornate of the orders, characterized by slender fluted columns and elaborate capitals decorated with acanthus leaves and scrolls. There are many variations.

The name "Corinthian" is derived from the ancient Greek city of Corinth, although the style had its own model in Roman practice, following precedents set by the Temple of Mars Ultor in the Forum of Augustus (c. 2 AD). It was employed in southern Gaul at the Maison Carrée, Nîmes (illustration, below) and at the comparable podium temple at Vienne. Other prime examples noted by Mark Wilson Jones are the lower order of the Basilica Ulpia and the arch at Ancona (both of the reign of Trajan, 98–117 AD) the "column of Phocas" (re-erected in Late Antiquity but 2nd century in origin), and the "Temple of Bacchus" at Baalbek (c. 150 AD).

Greek Corinthian order[edit]

The Corinthian order is named for the Greek city-state of Corinth, to which it was connected in the period. However, according to the architectural historian Vitruvius, the column was created by the sculptor Callimachus, probably an Athenian, who drew acanthus leaves growing around a votive basket. Its earliest use can be traced back to the Late Classical Period (430-323 BC). The earliest Corinthian capital was found in, dated at 427 BC.

Roman Corinthian order[edit]

Proportion is a defining characteristic of the Corinthian order: the "coherent integration of dimensions and ratios in accordance with the principles of " are noted by Mark Wilson Jones, who finds that the ratio of total column height to column-shaft height is in a 6:5 ratio, so that, secondarily, the full height of column with capital is often a multiple of 6 Roman feet while the column height itself is a multiple of 5. In its proportions, the Corinthian column is similar to the Ionic column, though it is more slender, and stands apart by its distinctive carved capital. The abacus upon the capital has concave sides to conform to the outscrolling corners of the capital, and it may have a rosette at the center of each side. Corinthian columns were erected on the top level of the Roman, holding up the least weight, and also having the slenderest ratio of thickness to height. Their height to width ratio is about 10:1.

One variant is the Tivoli Order, found at the Temple of Vesta, Tivoli. The Tivoli Order's Corintinan Capital has two rows of Acanthus (ornament) and its abacus is decorated with oversize fleuron (architectural) in the form of hibiscus flowers with pronounced spiral pistils. The column flutes have flat tops. The frieze exhibits fruit swag (motif) suspended between bucrania. Above each swag is a rosette (design). The cornice does not have modillions.

Gandharan capitals[edit]

Indo-Corinthian capitals are capitals crowning columns or pilasters, which can be found in the northwestern Indian subcontinent, and usually combine Hellenistic and Indian elements. These capitals are typically dated to the 1st centuries of our era, and constitute important elements of Greco-Buddhist art of Gandhara.

The classical design was often adapted, usually taking a more elongated form, and sometimes being combined with scrolls, generally within the context of Buddhist stupas and temples. Indo-Corinthian capitals also incorporated figures of the Buddha or Bodhisattvas, usually as central figures surrounded, and often in the shade, of the luxurious foliage of Corinthian designs.

Renaissance Corinthian order[edit]

During the first flush of the Italian Renaissance, the Florentine architectural theorist Francesco di Giorgio expressed the human analogies that writers who followed Vitruvius often associated with the human form, in squared drawings he made of the Corinthian capital overlaid with human heads, to show the proportions common to both.

The Corinthian architrave is divided in two or three sections, which may be equal, or they may bear interesting proportional relationships, one with another. Above the plain, unadorned architrave lies the frieze, which may be richly carved with a continuous design or left plain, as at the U.S. Capitol extension (illustration, left). At the Capitol the proportions of architrave to frieze are exactly 1:1. Above that, the profiles of the cornice moldings are like those of the Ionic order. If the cornice is very deep, it may be supported by brackets or modillions, which are ornamental brackets used in a series under a cornice.

The Corinthian column is almost always fluted. If it is not, it is often worth pausing to unravel the reason why (sometimes simply a tight budget). Even the flutes of a Corinthian column may be enriched. They may be filleted, with rods nestled within the hollow flutes, or stop-fluted, with the rods rising a third of the way, to where the entasis begins. The French like to call these chandelles and sometimes they end them literally with carved wisps of flame, or with bellflowers. Alternatively, beading or chains of husks may take the place of the fillets in the fluting, for Corinthian is the most playful and flexible of the orders. Its atmosphere is rich and festive, with more opportunities for variation than the other orders.

Elaborating upon an offhand remark when Vitruvius accounted for the origin of its acanthus capital, it became a commonplace to identify the Corinthian column with the slender figure of a young girl; in this mode the classicizing French painter Nicolas Poussin wrote to his friend Fréart de Chantelou in 1642

The beautiful girls whom you will have seen in Nîmes will not, I am sure, have delighted your spirit any less than the beautiful columns of Maison Carrée for the one is no more than an old copy of the other.

The proportions of the orders were by the ancients formed on those of the human body, and consequently, it could not be their intention to make a Corithian column, which, as Vitruvius observes, is to represent the delicacy of a young girl, as thick and much taller than a Doric one, which is designed to represent the bulk and vigour of a muscular full grown man.
