Abraham Men.
This was the name bestowed upon a class of vagabonds who wandered over the country dressed in grotesque fashion, pretending to be mad and working upon the fears or the charity of people for alms. They were common in the time of Shakespeare, and were found even as late as the Restoration. The slang phrase "to sham Abraham," is a survival of the practice. There was a ward in Bethlehem (or Bedlam) Hospital, called the Abraham Ward, and hence probably arose the name of these beggars. Harmless lunatics who had been discharged were often to be seen roaming about the country and were allowed a great deal of licence in consequence of their weak-mindedness. Accordingly, the impostors above mentioned, who used generally to eke out the gifts of the charitable by stealing, when detected in their theft, would plead, as a rule, lunacy as an excuse of their crime.
