Triglyph is an architectural term for the vertically channeled tablets of the
Doric frieze, so called because of the angular channels in them, two perfect and one divided, the two
chamfered angles or hemiglyphs being reckoned as one. The rectangular recessed spaces between the tri
glyphs on a Doric frieze are called
metopes. The raised spaces between the channels themselves (within a triglyph) are called
femur in Latin or
meros in Greek.
