The sun gives spirit and life to plants and the earth nourishes them with moisture. - Leonardo da Vinci

Verrà il tempo in cui l’uomo non dovrà più uccidere per mangiare, ed anche l’uccisione di un solo animale sarà considerato un grave delitto

He who thinks little, errs much.

First, of things relating to animals; secondly, of irrational creatures; thirdly of plants; fourthly, of ceremonies; fifthly, of manners; sixthly, of cases or edicts or quarrels; seventhly, of cases that are impossible in nature [paradoxes], as, for instance, of those things which, the more is taken from them, the more they grow. And reserve the great matters till the end, and the small matters give at the beginning.
