The White-Boys, or Whiteboys, (also called Levellers) were an eighteenth century Irish secret society that defended, with violence, Irish tenant farmers rights.
Elena Grainger in her biography of James Martin, Martin of Martin Place, describes this work as 'a story of a ride from Dublin to Cork demonstrating his lifelong aptitude for convincing descriptions of places he had never seen but had read about' (23). The story may have been retold to Martin by his mother or father who were from Cork, Ireland.
