Teaching not by rote but through play? That's credited to the 17th-century Czech pastor and thinker called Jan Amos Comenius. Splitting schoolchildren up into year groups? That's Comenius. Universal education for all, rich and poor? That's down to him too. Nearly four centuries ago, Comenius came up with principles of modern education but they were only implemented hundreds of years after his death. That these ideas are now so widely accepted obscures the fact that they were ground-breaking - indeed too radical - in his day. Comenius lived through turbulent times: the devastating Thirty Year served as the backdrop to much of his life. He was suffered personal tragedy during the bitter battles between Protestants and Catholics in Europe and spent most of his adult life in exile. Joining Rajan Datar to analyse the contribution to modern thinking made by Comenius in this, the 350th anniversary year of his death are Dr. Vladimir Urbanek, Head of the Department of Comenius' Studies and Early Modern Intellectual History at the Czech Academy of Sciences in Prague; Howard Hotson, Professor of Early Modern Intellectual History at Oxford University; and Dr. Yoanna Leek from the Faculty of Education Sciences at Lodz University in Poland.
