"a long strip from his shirt-tail hanging down behind him"

   Those who interpret Don Quixote as containing a subversive, anti-religious undercurrent cite this as one of its most openly blasphemous passages - the deranged hidalgo, stripped  from the waist down and enacting his penance in the Sierra Morena, fashions a makeshift rosary from the material covering his naked behind.  From the second edition onwards Quixote substitutes galls from a nearby cork tree as a less provocative alternative, suggesting that Cervantes realised he was treading too close to a perilous line (See note to page 51).
