Presents new evidence from the diary and correspondence of Ottilie von Goethe establishing that a letter in which she describes a drawing by Leonardo was written in the fall of 1857 to August Grahl, and that the drawing in question, then in Grahl's collection, could not be the "fugitive" sheet of anatomical drawings in the Schlossmuseum, Weimar, originally in the collection at Windsor Castle. [Appendix with transcriptions of the letter and the diary excerpt.]
