Title: Corinthian order
Content:  The Corinthian order (Greek Κορινθιακός ρυθμός, Latin Ordo Corinthius) is the last developed of the three principal classical orders of Ancient Greek architecture and Roman architecture. The other two are the Doric order which was the earliest, followed by the Ionic order. In Ancient Greek architecture, the Corinthian order follows the Ionic in almost all respects other than the capitals of the columns. 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 the most ornate of the orders. This architectural style is characterized by slender fluted columns and elaborate capitals decorated with acanthus leaves and scrolls.

There were two main classical orders of Greek architecture, the Doric and the Ionic, with the Corinthian order only appearing in the Classical period, and not becoming dominant until the Roman period. The most obvious features of the three orders are the capitals of the columns, but there are significant differences in other points of design and decoration between the orders. These names were used by the Greeks themselves, and reflected their belief that the styles descended from the Dorian and Ionian Greeks of the Dark Ages, but this is unlikely to be true. The Doric was the earliest, probably first appearing in 
Title: Doric order
Content:   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 Greek Doric column was fluted or smooth-surfaced, 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 
Title: Classical order
Content:  There are three distinct orders in Ancient Greek architecture: Doric, Ionic, and Corinthian. These three were adopted by the Romans, who modified their capitals. The Roman adoption of the Greek orders took place in the 1st century BC. The three ancient Greek orders have since been consistently used in European Neoclassical architecture. Sometimes the Doric order is considered the earliest order, but there is no evidence to support this. Rather, the Doric and Ionic orders seem to have appeared at around the same time, the Ionic in eastern Greece and the Doric in the west and mainland. Both the Doric and the 
Title: Ionic order
Content:   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 (a plainer Doric), and the rich variant of Corinthian called the composite order. Of the three classical canonic orders, the Ionic order has the narrowest columns. The Ionic capital is characterized by the use of volutes. The Ionic columns normally stand on a base which separates the shaft of the column from the stylobate or platform while the cap is usually enriched with egg-and-dart. The ancient architect and architectural historian Vitruvius associates the Ionic with feminine proportions (the Doric representing the masculine).

By the 4th century BC, Greek architects and stonemasons had developed a system of rules for all buildings known as the orders: the Doric, the Ionic, and the Corinthian. They are most easily recognised by their columns (especially by the capitals). The Doric column is stout and basic, the Ionic one is slimmer and has four scolls (called volutes) at the corners of the capital, and the Corinthian column is just like the Ionic one, but the capital is completely different, being decorated with acanthus leafs and four scrolls.

The Doric order was much used in Greek Revival architecture from the 18th century onwards; often earlier Greek versions were used, with wider columns and no bases to them. The ancient architect and architectural historian Vitruvius associates the Doric with masculine proportions (the Ionic representing the feminine). It is also normally the cheapest of the orders to use. When the three orders are superposed, it is usual for the Doric to be at the bottom, with the Ionic and then the Corinthian above, and the Doric, as "strongest", is often used on the ground floor below another order in the storey above.
Title: Ancient Greek architecture
Content:  Ancient Greek architecture of the most formal type, for temples and other public buildings, is divided stylistically into three Classical orders, first described by the Roman architectural writer Vitruvius. These are: the Doric order, the Ionic order, and the Corinthian order, the names reflecting their regional origins within the Greek world. While the three orders are most easily recognizable by their capitals, they also governed the form, proportions, details and relationships of the columns, entablature, pediment, and the stylobate. The different orders were applied to the whole range of buildings and monuments. The Doric order developed on mainland Greece and spread to Magna Graecia (Italy). It

Title: Classical order
Content:  The Ionic order came from eastern Greece, where its origins are entwined with the similar but little known Aeolic order. It is distinguished by slender, fluted pillars with a large base and two opposed volutes (also called "scrolls") in the echinus of the capital. The echinus itself is decorated with an egg-and-dart motif. The Ionic shaft comes with four more flutes than the Doric counterpart (totalling 24). The Ionic base has two convex moldings called tori, which are separated by a scotia. The Ionic order is also marked by an entasis, a curved tapering in the column shaft. A column of the Ionic order is nine times its lower diameter. The shaft itself is eight diameters high. The architrave of the entablature commonly consists of three stepped bands (fasciae). The frieze comes without the Doric triglyph and metope. The frieze sometimes comes with a continuous ornament such as carved figures instead.
