 Sebastian Fabian Klonowic (known as Acernus) decided to employ the stanza in a longer epic poem.His "Flis, to Jest Spuszczanie Statków Wisłą i inszymi rzekami" ("The lightening or expediting barges on the Vistula river and other rivers") is because of its stanzaic form an exceptional work, perhaps not only in Polish literature.The whole poem is 471 stanzas long and probably no other work can be compared to it.
