In this biography the author extends our understanding of the personality and work of the man he has characterized as essentially a reformer whose ideal was the pure church. Since 1915, the date of the last similar study of Hus, a great deal of new information has become available, especially in the Czech language. Professor Spinka has based his study on these new materials and on critical works about Hus. He has also abstracted Hus' writings, in Latin and in Czech, thereby clarifying what Hus taught.
