During some research I’ve come across a wonderful woodcut engraving of the pillory at Marlborough in an article on obsolete punishments by Llewellyn Jewitt in “The Reliquary” Quarterly Journal, January 1861.
The pillory was used for a range of moral and political crimes, most notably for dishonest trading - the modern equivalent of implementing trading standards. Its use dates back to Anglo-Saxon times where it was known as “Healsfang” or “catch-neck”. In France it was called the pillorie. It was well established as a use of punishment after the Conquest. It was considered to be a degrading punishment with offenders standing in the pillory for several hours to be abused by fellow citizens, sometimes being pelted with all manner of organic material such as rotten eggs, mud and filth. If that was not enough, sometimes the offender was drawn to the pillory on a hurdle, accompanied by minstrels and a paper sign hung around his or her head displaying the offence committed.
