A stanza with this number of lines in “chained rhyme” typically follows a stanza in “kissing rhyme.” A poetic form based on stanzas with this many lines uses the technique of “backward crossing” to rearrange this many words that end the lines of each (15[1])stanza. In English, this is the number of metrical feet in an (15[1]-5[4])alexandrine. A (15[1]-5[1])poetic form (15[2])consisting of this many stanzas of this many (-5[1])lines, followed by an (15[1])envoi, was (15[1])developed (15[1])by Arnaut Daniel and other (10[1])(*) troubadours. (-5[1])Petrarch’s (-5[1])epic poem Africa uses a metric scheme made of this many dactyls, which Homer used (10[1])for (10[2])the Iliad and the (10[1])Odyssey. (10[1])This many lines occur after a change of (10[1])tone known as the volta in Italian sonnets, which itself occurs after an octet. For 10 points, give this number of lines in two (10[1])tercets, or one (10[1])sestet. (10[7])■END■
