Hidden figure in Leonardo da Vinci notebook revealed

Or more like an erased figure is "revealed"

Ewwww, this website... Interesting article but the title is quite misleading, it is erased, not hidden.

Don't get me wrong, Leonardo's work was very important, but I am okay with not knowing something he didn't believe was worth knowing.

Have you ever deleted something, and then wished you hadn't? I have drawn things on paper that I erased to try and make a new go at it, only to regret having erased it in the first place.

The recovery of an erased item in such an historical document is reason enough for me, and a great hack to be applied to other documents too.

Right, that's life, and I'm fine with that, but also fine with people wanting to know.

Any chance you're the same eggy from SE?

Hey, even Leonardo got stuck in meetings and felt the need to doodle around.
