double-rhyme verse. The Rubaï or quatrain is also a common form. It consists of four hemistichs rhyming with each other. The only other verse-form that occurs with any frequency is the Mukhemmes or Cinquain, a succession of stanzas, each formed of two beits and a hemistich, the five hemistichs of the first stanza having the same rhyme, whilst the first four of each succeeding stanza take a new rhyme and the fifth rhymes with the first stanza to the end of the poem. Another form of the Mukhemmes differs only from the first in that the last hemistichs of the stanzas rhyme with each other only, independently of the other hemistichs of the first stanza. The Murebbes or foursome song occurs once only in the Nights[1] and consists of a series of two-beit stanzas, the first three hemistichs of each of which rhyme with each other only, independently of the rest of the poem, and the fourth with that of every other stanza.
The Muweshshih or Ballad is another form which occurs once only in the Thousand and One Nights.[2] It is, perhaps, the most elaborate verse-form in the language and is said to have been invented by the Muslim poets of Spain, shortly after the Conquest, and to have been adopted from them by their brethren of Egypt and Syria. It consists of a succession of three-line stanzas, in the first of which all six hemistichs end with the same rhyme. In the second and succeeding stanzas, the first line and the first hemistich of the second line take a new rhyme; but the second hemistich of the second line resumes the rhyme of the first stanza and is followed by the third line
