Triglyph

The triglyphs (also the triglyph, Greek τρίγλυφος Engl. "Three grooves / notches " ) is a plate on the frieze of the Doric order with two full and two half inner outer grooves ( without this Diglyphe also called ) between the metopes, with whom they form the triglyph.

Formerly generally thought, the triglyphs derive from a carved ornament or a special wooden connecting the transverse architraves, which span the columns, starting with the longitudinally running purlins of the roof structure in the original wooden beams Greek temple, it is now also the assumption expressed that the triglyph has a purely ornamental character and is not derived from the wooden structure of archaic temple. The fact that the constructive context already in the Late Hellenistic not assumed or understood, show examples of triglyphs, which were worked as vortretende reliefs with three feet, offering bowls or the like instead of the slots, such as on the little Propylaea at Eleusis or on a workpiece on Samos.

With the advent of stone temple architecture, there was a problem in the rules of proportion of the Doric order, the Doric corner conflict is called. The triglyph plays a crucial role. Since the uniform rhythm of the design elements demanded that a triglyph had to be mounted on the column axis of the corresponding column always resulted in the Ecktriglyphe a conflict. For the triglyphs of Steinbaues are much narrower than the architrave also centrally located above the column axis is deep. In order to ' flush ' complete with the Architravkante on the corner, the Trigylphe from the column axis to the corner of the building had to be postponed, what the uniform overall impression bothered. This conflict must have occurred late in the wooden buildings in the rest already, since it can also be detected in Olympia on Heraion. Its wooden pillars were only gradually replaced by stone columns, but his wooden beams had been on the corner conflict.

The triglyph can be found as an ornament in classicism and historicism.
