PREFACE

...pletion of this undertaking, each in his own language. We express here the gratitude we owe them for their precious cooperation.

We have but one goal: to open more widely the "archives" of Leonardo and thus offer definitive documents to criticism and to new studies. With all the writings of Leonardo da Vinci placed within the reach of scholars, each person will pause at the questions that concern them; and if the human spirit, through all social changes, does not remain indifferent to the great truths of art and pure science, the publication initiated with this volume will remain a living source of fruitful ideas and philosophical speculations.
