The manuscript’s name has changed over centuries to reflect its high-profile owners:

: Unlike Leonardo's other notebooks, which cover broad subjects, this codex focuses heavily on hydrodynamics, exploring whirlpools, currents, waves, and hydraulic engineering.

: The 72-page manuscript was written in Italian using Leonardo's signature mirror-image script, which reads from right to left.

Let it not be shapeless noise, nor the bleating of a cursor without aim.

Fourth: . Sparingly, but exactly where the fit is loose. A claim without a hook is a wall without mortar.
