The words and lyrics of the nursery rhyme 'Robert Barnes, fellow fine' relate to a simple blacksmith - we cannot perceive any hidden message.
However it was interesting to investigate notable people in history who were named 'Robert Barnes'.
Research showed that a Prior and Master of the Augustinian community at Cambridge was called Robert Barnes(1495 - 1540).
Martin Luther was also of the Augustinian community and Robert Barnes adhered to Luther's teachings and he published these ideas in "Sentences", a collection of nineteen thesis defending the reformed Protestant faith.
He was sent to the Tower of London because of his beliefs and died the death of a martyr at Smithfield where he was burnt alive.
Luther prompted a new religion called Protestantism. The term 'Protestant' was adopted when followers of Martin Luther protested against efforts to limit the spread of Luther's new religious ideas
