Even today, children innocently chant this old nursery rhyme, bringing the old saying into reality, “Ignorance is Bliss”. It’s eerie, to think that this old rhyme in fact gives a perfect description of one of Europe’s worst nightmares, the Great Plague. Many people forget the horrors of the Plague, and when they do remember and think about it, Public heath is rarely a factor that plays a big part when people start to think things through.
