The Irrational Sonnet -- An Oulipian form

An irrational sonnet has 14 lines, just as the traditional sonnet, but differs in its stanza-division and rhyme:  there are five stanzas--containing 3, 1, 4, 1 and 5 lines, respectively (these being the first five digits of the irrational number pi), and a rhyme scheme of   AAB  C  BAAB  C  CDCCD.  This form was devised by Oulipo member Jacques Bens (1931-2001) in 1963.   (Previous postings concerning the Oulipo occurred on March 25 and August 5.)
