The Kitab Sirr Al-Asrar, later entitled "Secretum Secretorum" and attributed (dubiously) to Aristotle, purports to be a manuscript delivered in the form of multiple messages from the same ancient philosopher to Alexander the Great. Advising him on medicine, philosophy, battle, governance, and spiritual piety, the text is a cross section of medieval social order and spiritual thinking. This edition has been rendered from archaic English into modern language.
