Dodecasyllable
Dodecasyllable verse is a line of verse with twelve syllables. 12 syllable lines are used in a variety of poetic traditions.
Jacob of Serugh, a Miaphysite Bishop of Batnan da-Srugh, also called 'Flute of the Spirit' who composed in the dodecasyllabic verse more than seven-hundred verse homilies, or mêmrê, of which only 225 have thus far been edited and published.
With the so-called "political verse" it is the main metre of Byzantine poetry. It is also used in Italian and French poetry, and in poetry of the Croats. In an Anglo-Saxon and French context, the dodecasyllable is generally called the "alexandrine", after the French equivalent.
