INTRODUCTION

Charles Ravaisson-Mollien; the Trivulzio Codex, by Luca Beltrami; the Codex on the Flight of Birds and Anatomy A, by Teodoro Sabachnikoff; and the great Codex Atlanticus is currently in press, of which approximately one thousand large folio pages and 920 heliotype plates—reproducing over 1200 originals—have already been released ⁽⁵⁾.

And there remain unpublished sheets scattered here and there, the continuation of the great collection of the Royal Library at Windsor, the volumes of the British Museum and the South Kensington Museum Now the Victoria and Albert Museum in London, a complex of over 1500 pages!

The publication of this scientific treasure was promised by Teodoro Sabachnikoff in his preface to the Codex on the Flight of Birds ⁽⁶⁾, and the promise will be kept. The other volumes of the Windsor manuscripts will follow the present one, and, simultaneously or after them, those of the British Museum and the South Kensington Museum.
