I Prolegomena and General Introduction to the Book on Painting.

Clavis Silillorum.

1. In the few instances in which Leonardo has written from left to right in the ordinary way this is stated in a note. In all other cases the writing is backwards.

2. The numbers printed above the line in the revised text: ², ³, ⁴ &c. indicate the heads of the lines in the original MS. In many instances the breaking off of the lines in the original MS. accounts for peculiarities in the construction of Leonardo’s sentences. In the translation the numbers refer only to the footnotes and they have been introduced in such passages, which require an explanation. [note: the revised (Italian) text is int included in this online edition - Liam]

Taken from The Notebooks of Leonardo da Vinci edited by Jean Paul Richter, 1880.
