Leonardo's Notebooks
"Already in 1630, the Barnabite Antonio Mazenta speaks of the dispersal of the Leonardo manuscripts, and singles out Pompeo Leoni, a sculptor at the court of the King of Spain, as one of those chiefly responsible not only for losing part of the collection, but even worse, for rearranging the order of its contents. Indeed, in an effort to sort the artistic drawings from the technical ones, and to put together the scientific notes, he split up the original manuscripts, cut and pasted pages and created two separate collections."
That's really a shame.
