DVD video (lasting 9’ min 23’’) commissioned by the State Archives in Florence for the exhibition “Leonardo Da Vinci: the true image” in collaboration with Cristina Amione, and Nicolò Bruna in charge of the technical aspect of filming, directing and assembling.

The video describes the various “ductus” in Leonardo’s letters, i.e. the line sequence making up the individual letters. It illustrates that the da Vinci’s style of writing was the same as his contemporaries, but written backwards like a mirror image.
