Pythagoras and the Delphic Mysteries by Edouard Schuré [1906]

This is a short biography of Pythagoras, written from a Theosophical, esoteric perspective. No actual texts of Pythagoras have survived: we only have second hand summaries and pastiches, such as the Golden Verses. However, his impact on successive thinkers has been enormous. This work serves as a short, readable introduction to the man, his thought and times, and the modern esoteric interpretation of his place in the history of ideas.
