DaVinci's Notebook

Slashdot refers us to the British Library today.

They have published scans of Leonardo DaVinci's personal notebook, loaded with sketches, writings and quotes in his own handwriting. You can flip through the pages, and helpful pop-up text translates a few interesting bits, like these "Profetie" (or prophetic riddles) DaVinci collected:

Riddle: The dead will come from underground and by their fierce movements will send numberless human beings out of this world.
Answer: Iron, which comes from under the ground, is dead, but the weapons are made of it which kill so many men.

Riddle: There will be many which will increase their destruction
Answer: The ball of snow rolling over the snow

Sounds like a good secret society passphrase to me.
