Pentina
The pentina is an accentual-syllabic poetic form, characterized by the use of five verses of five lines each, with a two-line envoi, for a total of 27 lines. It is similar to the French form, the sestina, which is characterized by six verses of six lines each, with a final 3-line envoi. Its creation in 1995 by American poet and songwriter Leigh Harrison was documented in an article, "The Joys of the Pentina" (Medicinal Purposes Literary Review, Vol. II, No. XII, published in 2005). The Pentina form is also described in Lewis Turco's "The Book of Forms / Odd and Invented Forms" which was published in 2011 in the U.S.
