Vasari says, and rightly, in his Life of Leonardo, "that he laboured much more by his word than in fact or by deed," and the biographer evidently had in his mind the numerous works in Manuscript which have been preserved to this day.
Leonardo made use of an orthography peculiar to hi.
This obvious peculiarity in the writing is not, however, by any means the only obstacle in the way of mastering the text.
And as, after all, Leonardo\'s handwriting runs backwards just as all Oriental character runs backwards-that is to say from right to left-the difficulty of reading direct from the writing is not insuperable.
Speaking from my own experience, the persistent use of it is too fatiguing and inconvenient to be practically advisable, considering the enormous mass of Manuscripts to be deciphered.
Vasari observes with reference to Leonardos writing: "he wrote backwards, in rude characters, and with the left hand, so that any one who is not practised in reading them, cannot understand them." The aid of a mirror in reading reversed handwriting appears to me available only for a first experimental reading.
The handwriting is so peculiar that it requires considerable practice to read even a few detached phrases, much more to solve with any certainty the numerous difficulties of alternative readings, and to master the sense as a connected whole.
That, notwithstanding this eagerness to possess the Manuscripts, their contents remained a mystery, can only be accounted for by the many and great difficulties attending the task of deciphering them.
This is proved not merely by the prices which they commanded, but also by the exceptional interest which has been attached to the change of ownership of merely a few pages of Manuscript.
It is certain that during the XVIth and XVIIth centuries their exceptional value was highly appreciated.
To us, now, it seems almost inexplicable that these valuable and interesting original texts should have remained so long unpublished, and indeed forgotten.
