The Da Vinci Notebooks
This, when fighting with serpents eats the sow-thistle and is free.
This [bird] gives sight to its blind young ones, with the juice of the celandine.
This, when chasing rats first eats of rue.
This beast cures its sickness by eating of ivy.
This creature when it wants to renew itself casts its old skin, beginning with the head, and changing in one day and one night.
This beast after its bowels have fallen out will still fight with the dogs and hunters.
