It isn't a theory it is a historical fact, children in Britatin in the past used to make up nursery rhymes to scare people, It is Ring of Roses, and the sneezing in the rhyme symbolises the ill people that fell to the plague, where as the end of the song "we all jump up with a 1,2,3" well says it all.
During Plague:
Ring a ring of roses (Flowers to Symbolise the fallen)
a pocket full of poses (The rashes on those suffering)
Atisho Atisho (Sneezies of those about to fall)
We all fall down (Death)
After Plague:
Fishes in the water (Life)
Swimming round and round (Life)
We all jump up with a 1,2,3. (Life)
The Plague was smallpox, which no suprises at the time was an epidemic, carried by black rats. "rattus rattus"
The great fire of London 1666 wiped out most of it, giving the medical profession time to develop an antidote.
Unfortunately some of us had to learn the meanings at school.
Fortunately my teachers were right and said one day I would need to know it.
There are many nursery rhymes you may never had heard of over here and they ALL symbolise something.
It's the way British history works, rhymes are easier to remember lessons and more frightening when used in the right moment.
I'm not even gonna get into "rock-a-bye baby"
