Leonardo Da Vinci, Artist, Thinker and Man of Science #261525

The great majority of his drawings have never been reproduced. No critic has even attempted to catalogue and classify these master pieces of taste and sentiment. It was to this part of my task that I first applied myself. And, among other results, I now offer the public the first descriptive and critical catalogue of the incomparable collection of drawings at Windsor Castle, belonging to her Majesty the Queen of England. Among the many previous volumes dedicated to Leonardo, students will seek in vain for details as to the genesis of his pictures, and the process through which each of them passed from primordial sketch to final touch. Leonardo, as is conclusively shown by my researches, achieved perfection only by dint of infinite labour. It was because the groundwork was laid with such minute care, with such a consuming desire for perfection, that the Virgin of Me Rocks, the Mona Lisa, and the 5. Anne are so full of life and eloquence.
