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 stanza. In English, this is the number of metrical feet in an alexandrine. A poetic form consisting of this many stanzas of this many lines, followed by an envoi, was developed (15[1])by Arnaut Daniel and other (*) troubadours. Petrarch’s (-5[1])epic poem Africa uses a metric scheme made of this many dactyls, which Homer used for (10[1])the Iliad and the Odyssey. This many lines occur after a change of tone known as the volta in Italian sonnets, which itself occurs after an octet. For 10 points, give this number of lines in two tercets, or one (10[1])sestet. ■END■
