- An ornament in the frieze of the Doric order, repeated at
equal intervals. Each triglyph consists of a rectangular tablet,
slightly projecting, and divided nearly to the top by two parallel and
perpendicular gutters, or channels, called glyphs, into three parts, or
spaces, called femora. A half channel, or glyph, is also cut upon each
of the perpendicular edges of the tablet. See Illust. of Entablature.
