Anta (architecture)

The Athenian Treasury in Delphi with two antae framing a set of two columns.

An anta (pl. antæ) (Latin, possibly from ante, 'before' or 'in front of'), or sometimes parastade is an architectural term describing the posts or pillars on either side of a doorway or entrance of a Greek temple - the slightly projecting piers which terminate the walls of the naos.^[1] It differs from the pilaster, which is purely decorative, and does not have the structural support function of the anta.

Anta

An anta behind a row of columns at the Erectheion, a prostyle temple, Athens (built between 421 and 406 BCE). A decorative capital can be seen at the top.

In contrast to columns or pillars, antae are directly connected with the walls of a temple. They owe their origin to the vertical posts of timber employed in the early, more primitive palaces or temples of Greece, as at Tiryns and in the Temple of Hera at Olympia. They were used as load-bearing structures to carry the roof timbers, as no reliance could be placed on walls built with unburnt brick or in rubble masonry with clay mortar. Later, they became more decorative as the materials used for wall construction became sufficient to support the structure.^[2]

When there are columns between antae, as in a porch facade, rather than a solid wall, the columns are said to be in antis. (See temple.)^[2]

Anta capitals

The anta is generally crowned by a stone block designed to spread the load from superstructure (entablature) it supports, called an "anta capitals" when it is structural, or sometimes "pilaster capital" if it is only decorative as often during the Roman period. In order not to protude unduly from the wall, these anta capitals usually display a rather flat surface, so that the capital has more or less a brick-shaped structure overall. The anta capital can be more or less decorated depending on the artistic order it belongs to, with designs, at least in Greek architecture, often quite different from the design of the column capitals it stands next to. This difference disappeared with Roman times, when anta or pilaster capitals have design very similar to those of the column capitals.^[3][4]

Distyle in antis

Early Greek temples such as the 6th century Siphnian Treasury had antae on both side of the porch, framing a set of columns (a disposition named "distyle in antis", meaning "two columns in between antae"). This was an early type of temple construction (the "distyle temple") meant to reinforce weak wall construction by head posts, the antae. Sometimes, the walls were in brick, and thus needed this kind of reinforcement, as in the Heraeum of Olympia (c. 600 BCE).^[5]
