Glyconic ( Latin: glyconeus; from Glycon, a Greek lyric poet) is a form of meter in classical Greek and Latin poetry. The glyconic line is the most basic form of Aeolic verse, and it is often combined with others.
The basic shape (often abbreviated as gl) is as follows:
x x - u u - u -
Here "x" indicates an anceps, "-" a longum, and "u" a brevis. "x x" is known as the Aeolic base, which can be --, -u, or u-. "- u u -" is a choriambus. As in all classical verse forms, the phenomenon of brevis in longo is observed, so although the last syllable can actually be short or long, it always "counts" as long.
The acephalous ("headless") version (^gl), also known as the telesillean (Latin: telesilleus), is:
x - u u - u -
Runs of glyconic lines are often ended by a pherecratean (a glyconic without the last brevis: xx-uu--), as in the glyconic and pherecratean stanzas found in Anacreon and Catullus (i.e. Catullus 34 and 61). The combination of glyconic and pherecratean is given the name priapean (Latin: priapeus):
x x - u u - u - | x x - u u - -Usage examples of "glyconic".
Systems of Glyconics and Asclepiads are, if I mistake not, easily manageable, and are only thought foreign to the genius of our language because they have never been written on strict principles of art by a really great master.
In fact, it was fixed, Mr Thewless saw, upon some unseen goal or conception with quite as much concentration as any of those earlier pupils had ever brought to the ultimate mysteries of the Glyconic and Pherecratean metres .
