High Quality Content by WIKIPEDIA articles! A fabliau (plural fabliaux) is a comic, often anonymous tale written by jongleurs in northeast France between ca. 1150 and 1400. They are generally characterized by an excessiveness of sexual and scatological obscenity. Several of them were reworked by Giovanni Boccaccio for the Decameron and by Geoffrey Chaucer for his Canterbury Tales. Some 150 French fabliaux are extant, the number depending on how narrowly fabliau is defined. According to R. Howard Bloch, fabliaux are the first expression of literary realism in Europe.
