Leonardo da Vinci: Quaderni d’anatomia I-VI. Fogli della Royal Library di Windsor, pubblicati da Ove C.L. Vangensten, A. Fonahn, H. Hopstock. 6 vols.

Leonardo, “the greatest artist and scientist of the Italian Renaissance, was the founder of iconographic and physiologic anatomy” (Garrison). He made over 750 sketches of all the principal organs of the body, drawings which were adequately reproduced only in recent times. His notes accompanying the drawings are in mirror-writing. Text in Italian, English, and German.

For more about Leonardo's anatomical work see a short essay I wrote on HistoryofInformation.com at this link.
